A Guide to OVPM

Introduction OpenView Performance Manager 5.0 (OVPM) generates graphical and tabular displays from a variety of OpenView data sources. OpenView Performance Manager version 3 and earlier, also known as PerfView provided a similar function for the OpenView Performance Agent (MeasureWare). This document should serve as a guide to assist a knowledgeable PerfView user in getting started using the OVPM 5 product. The document is organized into typical PerfView tasks.

Hint: PerfView and OVPM 5 perform similar functions. They exist in the same environments. The OVPM 5 product was not designed to be a perfectly compatible upgrade from PerfView but rather a re-engineering of the near real-time data viewing functionality adjusted to the new user paradigm of web interface.

This means that OVPM 5 will not necessarily do things exactly the same way that PerfView did. Some things will be better, some will be worse. To get the most out of this tool, you should plan on abandoning some of your current procedures, developed to work around the strengths and weaknesses of PerfView, and develop new procedures that work well with OVPM.

For more information on PerfView or OVPM, consult the documentation that came with that tool. If you are new to OVPM, then running a copy while you are reading this document may prove helpful. At some points in this document, you may see the command [Requires Java Graph]. This means that this feature is not available when you draw an HTML graph. You should draw a Java Graph instead.

High-Level Comparison

PerfView OVPM 5

PerfView displays data from:

OpenView Performance Agent (OVPA), also known as VP-PA and MeasureWare

VantagePoint 6.0 agent MDC.

OVPM displays data from:

OpenView Performance Agent (OVPA), also known as VP-PA and MeasureWare

OpenView Operations Agent - Embedded Performance Component

OpenView Reporter database

OpenView Internet Services

PerfView uses DCE and NCS datacomm. PerfView/NT may use UDP datacomm as well.

OVPM uses DCE, NCS, UDP datacomm, plus the firewall friendly BBC protocol, and database remote access protocols, depending on the data source capabilities.

PerfView/Unix displays data using Motif. This interface can be exported to another Unix system using X-Windows technology.

PerfView/NT displays data using Microsoft Windows. This interface cannot be easily exported to another system.

OVPM displays data using a web browser interface. This interface is easily exported to any platform (Unix, NT, Linux, etc.) that supports a web browser.

PerfView graphs and tables can be placed on a web page through batch scripts and data conversion programs.

OVPM graphs and tables are web objects and can be easily included in web pages.

PerfView Monitor can receive and display alarms from OVPA

Use OpenView Operations or an SNMP event console to display alarms.

PerfView Planner projects future values for a metric, based on trends in the past.

OVPM currently does not have this feature but it can display baselines of average past values for any metric.

7

Getting Started

To start PerfView, start a terminal window on the Unix system where PerfView is installed. Export the display back to your local system if needed. Run the program: /opt/perf/bin/pv

8

To start OVPM, start a web browser from your local system.

For OVPM for Windows Access the URL: http://server/HPOV_IOPS/OVPM.htm

For OVPM for HP-UX or for Solaris Access the URL: http://server:port/OVPM

You can immediately see a difference. OVPM offers you the choice of two different user interfaces. Since the functionality of both interfaces is similar, it does not really matter which one you choose. For PerfView users, the Java Interface will probably feel more familiar (although the Web Forms will load faster across a slow internet connection and does not require that your system have a Java Plug-In).

The Java Interface does require a Java Plug-In (version 1.3 or 1.4). If your local system is using the Microsoft Internet Explorer browser, then it will automatically check and if necessary download this plug-in for you. If you are using the Netscape browser, then you

9

may have to load the plug-in manually. This is a one-time operation and instructions are provided in the Getting Started link from this initial web page.

The rest of this document will use the Java Interface for its examples, but you can also perform most of the same functions using the Web Forms. The sequence of operations may be slightly different, so feel free to choose the interface you prefer. The interactive graph features require Java Graphs, but these can be drawn from either interface.

The OVPM Java Interface

10

Connecting to a System

On PerfView, you next select Data Sources / Manage to bring up the system selection dialog. Select a System Group to display a list of systems, and then select one or more systems. Press Connect Systems to connect to all selected systems.

11

On OVPM, expand the System Group in the tree control on the left, and then click on the systems to select them. (No need to connect at this time; the connections are made as graphs are drawn.)

Note that as systems are selected or unselected, the list of Graphs in the right panel is adjusted to match the data sources on the systems selected.

12

Drawing a Graph

On PerfViews main dialog, select a system and data source. A list of matching graphs will appear in the Available Graphs section. Select the graph you want and press Draw.

PerfView will display the graph using the default Time Settings (Last 7 days).

13

If you want different time settings, you should first select the Settings / Global Time Settings main menu item to display the Global Time Settings Dialog.

Change the default settings to what you desire. On the main dialog, make sure the Use Global Time Settings box is checked, and then press Draw.

Alternately, once the graph is drawn, you can select Setting / Change Time Settings from the graph menu to get this dialog and apply it to the current graph only.

14

On OVPM, expand the selections of graphs in the right pane. Graphs may be organized into three levels inside the tree to make it easier to find the graph you want when there are many available.

Change the Time Settings on the bottom of this same screen unless you want the default (7 days, same as PerfView), and then press Draw.

15

16

Selecting the Date and Time Ranges

PerfView uses Time Settings to control how much data to include on a graph. You can draw a graph then select Settings / Change Time Settings to make these selections for a single graph. From the main PerfView screen, select Settings / Global Time Settings to set these values globally, then make sure the Use Global Time Settings box is checked on the main PerfView screen before drawing a graph.

The X-axis field selects how much time is in the graph.

Day, week, month, year, plus the Start Date slider

All data in the data source

This week, last week, this month, last month

Manual the start and stop dates are set using slider bars.

Exclude Weekends, Exclude Holidays and Start Shift and Stop Shift are ways to exclude data from the graph based on its day or time. Additional configuration dialogs are available to configure weekends and holidays.

Once a graph is drawn the current X-axis window can be moved left and right to cover different times by using the horizontal slider bar at the bottom of the graph.

Graph density is initially set automatically. Once a graph is drawn, you can select from a limited selection of Points Every values. PerfView may adjust these values depending on the amount of time in the X-axis, to avoid excessive processing overhead such as 1 years data at points every 5 minutes.

17

OVPM sets the width of the X-Axis using a duration selection. The Java Interface allows you to enter any number of minutes, hours, days or weeks. The Web Forms interface provides a list ranging from 1 hour to 365 days plus all. The location in time of this duration is set using the ending date. Now ends at the current date/time otherwise any date/time can be selected.

The Points Every selection allows you to select the granularity you wish. Auto will choose an appropriate value based on the duration selected. If you specify a Points Every that is too small to be reasonable, or that does not align into the Duration properly, OVPM will adjust it as needed.

The graph time range and Points Every can be set each time the graph is drawn and so are not saved with the graph definition.

18

Drawing the Same Graph for Multiple Systems

On PerfView, after connecting to each system, repeat the procedure for drawing a graph once for each one. PerfView does not allow selecting more than one Data Source at a time unless you generate a custom graph.

On OVPM, simply select all the systems you want graphed, then the graph you want and press Draw. OVPM will connect to each system and draw a graph for each one.

If the graph you are using contains only one metric, each system will appear as a separate metric on the same graph. This is comparable to the PerfView System Compare graph. If the graph contains multiple metrics, OVPM will then draw one graph for each system.

19

Zooming In on Data Zooming In refers to getting a closer look at a portion of time covered by the current graph. Drilling Down refers to looking at a portion of time covered by the current graph, but perhaps displaying different data, or current data in a different format. We will start with Zooming.

On PerfView you can Zoom In on a graph by dragging the cursor across the time period of interest. The current graph is redrawn to show only that time period. The Points Every setting for the graph may be adjusted to a smaller value during this operation. If so, then PerfView will retransmit data from the data source at the now higher resolution.

PerfView graphs can scan earlier and later in time using the scroll bar at the bottom of each graph. If scrolled to an area where data has not been retrieved, PerfView will retransmit data from the data source as necessary. This is similar to changing the time settings for a graph.

[Requires Java Graph] On OVPM the cursor can be used for different purposes. Initially when a graph is drawn, hovering the cursor over the graph will highlight the nearest data point and pop up its value. At the bottom of the page it shows the metric label and time.

To Zoom In, select the Zoom-In icon at the top of the graph (magnifying Glass with a Plus sign). It should indent indicating it is selected.

As you drag the cursor, the graph will be redrawn to show that time period. OVPM will not change the Points Every for the graph and so will not automatically retransmit data from the data source. If you want to retransmit data from the data source, use the OVPM Drill-Down feature. Once a graph is in the Zoom mode, you can scroll left and right across the original graph times. (Again, OVPM will not go back to the data source for more data during a Zoom or Scroll operation. It only does this during the Drill-Down function.)

20

To change the cursor operation back to showing the pop-up values, click the Zoom-In button again. This action does not affect the graph. To return to the original graph, press the Zoom-Out button (Magnifying Glass with a minus sign, just to the right of the Zoom-In button).

Vertical Slider

When a graph is drawn in PerfView, there is a slider on the left Y-Axis. This slider can be used to adjust the Y-Axis range to higher or lower values.

Some of the need for a vertical slider is handled by OVPMs use of a dual Y-axis. When drawing a graph where metrics have widely different ranges, the OVPM graph designer can assign some to the left Y-Axis and others to the right Y-Axis often making it possible to see all metrics at once.

[Requires Java Graph] OVPM does not have a vertical slider bar. What it uses instead is the same zoom-in function as is used for horizontal zooming. When you select the Zoom-in button then drag on the graph, you are dragging a rectangle. The result is that the graph will be redrawn with both the vertical and horizontal scales adjusted.

If you want to scale the Y-Axis to a smaller value, just zoom-in with a rectangle going fully left and right, but covering the desired area vertically.

If you want to increase the Y-Axis range, draw a rectangle that starts at or below the graph then extends above the existing Y-Axis. The Zoom-Out button returns the Y-Axis as well as the X-Axis to their original settings.

21

Drilling Down

On PerfView, the menu item Show / Drill Down allows you to see other data. Selecting this menu item displays the Drill Down dialog. You can select a different start date and stop date from within the graph time but many people do not use this feature. They will zoom the graph using the cursor so that it covers the time of interest then leave the Start and Stop date sliders alone in the Drill Down dialog.

The Drill to: selection allows you to select what type of data you want to see.

Time redraws the graph to agree with the Start/Stop sliders (same as a Zoom-in).

Numbers shows a table with the data that is used in the graph.

All other items indicate OVPA metric classes GLOBAL, APPLICATION, PROCESS, TRANSACTION, DISK, LVOLUME, NETIF.

These selections will show a table containing metrics from these data classes. You have some ability to select metrics in these tables, but not every metric in the class can be selected.

22

[Requires Java Graph] Drilling down in OVPM is a much more robust feature than it is in PerfView. When you drill down, you can display graphs as well as tables for any class on the system, including DSI data feeds and SPI data. Use this feature to request more in-depth information for the area you selected on the current graph.

To drill down in OVPM, click the Drill-Down button then drag a rectangular area on the graph. The Drill Down Properties window appears. Redraw the same graph with increased data granularity by clicking OK. This is similar to PerfViews Zoom feature. Use the Points Every selection to choose the X-Axis granularity or just leave it set to auto to have OVPM make a reasonable choice.

23

Select a different format for the data if desired. Select table to produce the same results as PerfViews Drill to numbers feature. Select excel to bring the data back to an excel spreadsheet where you can manipulate it further.

24

Select New Graph and the graph you want to draw to see a new graph for the area you selected. Select one of the graphs under Drill Down Tables to perform the same function as PerfViews Drill To GLOBAL, APPLICATION, PROCESS etc.

25

Handling Proxied Logfiles Proxied log files are performance agent log files that are mounted as a data source under another performance agent. This is often done when it is not possible or not desirable to access those logfiles directly from their originating systems. The systems may be located on an isolated network or the user may want to offload the data analysis activities from production systems to a backend system.

On PerfView, the Datasources / Manage menu item displays the PerfView Systems dialog. The List Sources button will list the data sources available from OVPA on a selected system. It shows log files being proxied from another system as well as DSI data sources, but it may be difficult to tell them apart using this display since it does not display what metrics are provided in each data source.

There is no good way of telling which systems are supporting proxied logfiles without listing sources for each one separately.

26

On OVPM, log files being proxied by a system will be displayed in the list of systems as [servername]proxyname where:

servername is the name of the system running the performance agent and

proxyname is the name of the system whose log files are represented.

System [ros87390tst]proxy indicates that the logfiles for the system proxy are mounted as a data source on the system ros87390tst. Select this system and draw graphs for it by selecting the system name like any other system. DSI data sources are not listed in this manner.

To see the DSI data sources and the metrics in any data source, use the Design tab of the OVPM user interface.

27

Local Data Sources Local data sources are a special case of proxied logfiles. They allow a log file that is present on the PerfView system to be temporarily added to the performance agent running on that system.

On PerfView, local data sources can be added using the PerfView Systems dialog. Local data sources are log files that are present on the PerfView system but are not otherwise connected to a performance agent. To add a local data source:

1. From the PerfView Systems dialog, select the menu item Manage / Add a local data source .

2. Select the log file from the list of local files on the PerfView system then select OK.

3. Wait several minutes while the server is started for this data source.

4. Back in the PerfView Systems dialog, select the name of the system where PerfView is running and press the List Sources button.

5. When the local log file appears, select it and do a Connect Systems.

OVPM does not handle local log files directly. To examine a local log file using OVPM, you should mount the logfile on any supported performance agent (it doesnt have to be the agent on the system where OVPM is installed):

1. Edit the perflbd.rc or perflbc.mwc file to include an entry for the desired logfile.

2. Restart that performance agent so it reprocesses its data source list.

3. Wait several minutes while the performance agent is restarted.

4. Enter the system name in OVPM as [agentsystemname]datasourcename.

28

Listing Data Sources

PerfView allows you to list the sources provided by the performance agent on a system. Use the PerfView Systems dialog, highlight the system and press the List Sources button. This lists the DSI data feeds as well as any proxied log files that are made available by OVPA on the system.

OVPM does not provide a List Sources function directly. High-level data sources are provided within the list of systems in the OVPM user interface. A high-level data source might be OVIS, Reporter, or a system with a performance agent. If a performance agent is proxing a log file for another system, then that system will also be listed in the list of systems.

To show a list of DSI data feeds that are made available by a performance agent:

1. Go to the OVPM Design tab, Sources sub-tab.

2. Select the system and agent that you want to interrogate.

3. Go to the Metrics tab and press Add The list of data classes, including DSI data feeds, will be displayed.

This technique works for all high-level data sources, OVOA, OVPA, OVIS, and Reporter etc.

Both PerfView and OVPM are inefficient in trying to locate which systems support a particular data source. The best way to determine this is to use the OpenView Reporter product. It provides a Configuration report titled Data Classes and Dates of Coverage that makes the task easy.

29

Handling Alarms

PerfView had an optional product called PerfView Monitor that accepted alarm events from the performance agents. These alarms were available in a list for browsing or further investigation.

OVPM does not have an alarm browser function. Use the superset capabilities in the OpenView Operations (OVO) product instead. This product accepts alarm events from the performance agents plus its own event agents and optionally those from SNMP devices. OVO 7 provides the ability to link from one of its events into a related OVPM graph or tabular display. OVO uses pieces of the OVPM user interface to design new graphs and draw additional graphs as desired.

30

Adding a New Graph

In PerfView, to create a new graph:

Connect to the data source(s) you want to graph.

Next select the menu item Graphs / Create New Graph .

Then select a data source from the list, the Class from that data source, optionally one instance name from multi-instance classes, and the metric. As each metric is selected, it is added to the Metrics to be Graphed list on the first display.

To change datasource, class, or instance, click OK then repeat the selection process.

When finished, draw the graph. You can then select visual settings and save the graph definition.

31

Later versions of PerfView allow you to save the graph as a Universal Template. Unless you choose this option, the graphs you save will always draw data from the same system/data sources you chose when you created the graph.

Universal Template graphs will prompt you to select which system to use when they are drawn. The graph will not draw any lines where the class, instance name, and metric name from the new system do not match those in the original graph. Graphs designed with more than one system will not work as expected when used as Universal Templates.

32

To design a new graph in OVPM:

Select the Design tab.

Select the Metrics tab on the right then press the Add button. This will bring up the Datasource Selection dialog.

Select the data source or system/datasource combination from the tree control.

33

Using the Metric Selection dialog, expand the class for this datasource, then check the metrics you want to graph. You can expand and check metrics from multiple classes if desired. You can set the visual settings for the chosen metrics at the bottom of this dialog, or come back and edit them later.

One special feature is illustrated here; by selecting a Filter: of BYNETIF=@ we have selected that all metrics should be separated by the network name (no matter what it is). A single name could have been chosen, such as BYNET-IF=TCP/IP but by using the @ construct, we can create a graph that adapts to different network names as they are encountered. More details on special graph features are described in the OVPM online help.

Press OK when you have finished selecting metrics. You will be returned to the Design tab, Metrics sub-tab.

From here you can add more metrics, edit the properties of metrics you have already entered, or press the Preview button to see the graph.

Make additional choices in the graph design using any of the design tabs General, Metrics, Sources, and Chart.

Press the Save or Save as button to save the graph definition. You will not be prompted as to whether you want to save as a Universal Template since in OVPM, ALL graphs templates are universal. When you save a graph, you supply a Family and Category name in order to make it easier to locate your graphs in the OVPM Display graph selection tree.

To draw your graph using a different system (or the same system, or multiple systems), go back to the OVPM Display tab. Select one or more systems that support the data sources you used in your graph. Your graph should appear inside the right-hand graph selection tree along with all the predefined graph templates. Select your graph, and press Draw.

34

Creating a Multi-Instance Graph

OVPM supports handling multi-instance data where there is more than one data record for a given time. One example of multi-instance data is the OVPA APPLICATION class. One record is written every five minutes for each user-defined application that was active during that time. GLOBAL data, on the other hand, is single instance, since exactly one record is written every five minutes, regardless of system activity.

PerfView allowed you to select a particular instance name when you were choosing metrics for a graph. OVPM also allows you to do this. The only problem with this approach is that it requires you to know the names of the instances at the time you create the graph. Furthermore, if the graph is drawn against a different system, then the instance names must be identical to the first system in order to be of use.

OVPM addresses multi-instance data through the use of filters. A filter is a comparison statement that is applied against the data for that metric. To create a graph showing the CPU usage and number of active processes for three applications, you could select metrics like you do in PerfView:

METRIC LABEL FILTER

APP_CPU_TOTAL_UTIL MemMgt CPU APP_NAME=memory_management

APP_ACTIVE_PROC MemMgt Procs APP_NAME=memory_management

APP_CPU_TOTAL_UTIL Root CPU APP_NAME=other_user_root

APP_ACTIVE_PROC Root Procs APP_NAME=other_user_root

Note the use of the LABEL feature to add human readable labels to the metrics in the graph.

This graph definition would work fine on systems that had applications named memory_management and other_user_root. What could you do if you wanted to include every valid application name on a system, even if it was not known at the time you created the graph? Obviously trying to guess the application names is not a good idea. We could use a PerfView-like Class Compare graph, but that only works for a single metric.

OVPM provides two special features that, used in concert, solve this problem.

The first we have already mentioned. Select a filter using the @ value.

This value matches every record in the class, but it will generate one metric for every unique metric name it finds.

35

By specifying APP_NAME=@ as a filter, we will create metrics for every application that was logged. Note that this filtering feature is not confined to filtering on the instance key metric.

You could decide to use APP_NUM or even APP_ACTIVE_PROC as a filter metric if you desire. Careful: you should avoid using a metric with a lot of possible values since this will generate a chaos of metrics. Avoid using APP_CPU_TOTAL_UTIL=@.

The second feature is a way to substitute a metric value into the metric labels. The code @@metric will substitute the metric value inside a label. Thus @@APP_NAME will be replaced by the application name. @@APP_NAME CPU will be the application name followed by CPU. For example: other_user_root CPU.

Our preferred way of handling multi-instance data in this example would become:

METRIC LABEL FILTER

APP_CPU_TOTAL_UTIL @@APP_NAME CPU APP_NAME=@

APP_ACTIVE_PROC @@APP_NAME Procs APP_NAME=@

You can see examples of this technique in the predefined graphs shipped with OVPM.

36

Class Comparison Graph The PerfView Class Comparison graph allows you to create a graph showing one metric across one or more instances of a multi-instance data class. In OVPM, this is simply a subset of its multi-instance graph functionality.

To obtain the same effect as the PerfView graph, design a graph for a multi-instance class specifying only one metric. (Use filter metric=@ and label @@metric as described in the previous section.) You will not need to select which instances to use since they will automatically match all instances on the data source.

As long as we are here, lets add a few more bells and whistles to our graph. Many times metrics you want to display together can have widely different ranges. In our case, the number of active processes can easily be greater than the maximum CPU percentage. OVPM allows you to specify that metrics be mapped to the left, or to an optional right Y-Axis.

Edit the processes metric by double-clicking on it in the metrics tab, or select it and then press the Properties button, then select Y-Axis: right.

Next go to the Chart tab on the right and select a label for the left Y-Axis of CPU Percent. Set the min and max for 0 and 100 on the left Y-Axis. Then select a label for the right Y-Axis of Process Count.

37

System Comparison Graphs

PerfView has a graph called System Compare. When you draw it, you will be prompted to select the systems you want to compare, then to select a metric from the GLOBAL class to use as a comparison. The System Comparison graph is then drawn with one line for each system.

38

OVPM does not provide a System Compare graph per-se. Instead, with its native universal template design, it allows any graph, from any class, to be used as a system comparison graph.

Simply select the systems you want to compare, using the OVPM Display tab.

Then select a graph that has the metric(s) you want to see and press Draw.

If the graph you selected has only one metric, then each system will be drawn on the same graph. See the OVPM Performance Comparison graph called CPU Comparison as an example.

Or see the CPU Gauges graph for a different representation.

If you choose a graph with more than one metric, then one graph will be drawn for each system you selected. You can use any graph for a system comparison and can use data from any class so long as each system selected supports that class. If any system does not support the class, then a warning will be issued and the resulting graph(s) will be drawn minus this system.

39

Multiple Data Source Graphs Most graphs you will use are fairly simple. They show data from a single data source and system. When you are comparing multiple systems, you see the same data metrics from the same data source on each system. Occasionally you may need to show different data from each source on the same graph. An example is where you might want to show response time from a system that was acting as a client, but show CPU utilization and network activity for a system that was acting as the application server for this client. Finally, you might want to include database SPI data from the backend database server system that is supporting the application server.

You need different metrics from different sources, all on the same graph.

Using PerfView, the only data source supported is the OpenView Performance Agent (OVPA) so a multiple-data-source graph must necessarily be from the same data source, but it can be for different data from different systems. For example:

This custom graph shows:

Response time for client ROS59395TST

CPU and network activity for application server hpptc0

40

Cache buffer and Session high water mark for database backend system ROSSPIDB6

You can create and save such a graph, but each time you draw it, it will show the same three systems. If you wanted to see information for a different client system, you would need to create a new graph.

Multiple data source graphs in OVPM are called complex graphs and can only be created and used with the Java User Interface. (The interactions involved just stretch the abilities of web browser forms too much to be useful.)

To create a multiple data source graph:

In the OVPM Java User Interface, select the Design tab, then the Sources tab on the right.

Check the box at the bottom labeled Complex Graph Design using multiple sources. This changes the dialog to allow multiple data sources to be defined. Each data source is assigned a unique name to make it easier to assign to different systems when the graph is drawn.

41

Under the Metrics tab, the Add button will have a Source: field with a drop-down showing the names of the data sources you have entered.

Select the source to show the metrics available from that data source.

After selecting a data source, choose metrics in the same way as you do for a simple graph.

42

Notice how choosing right axis for the Network Packets metric allows all metrics to be visualized without having to do a vertical scroll. It is now more obvious that a correlation exists between the network packet rate and the CPU used on the application server.

When you are satisfied, save the graph definition. When you draw the graph from the OVPM Display tab, you will get a pop-up dialog to allow you to change any of the systems used in the graph. Your data source names will be used to identify what type of system should be chosen for each source.

43

OVPM supports more data sources than just OVPA and so allows you to mix data from OV Internet Services, OVPA, OVOA and Reporter, all on the same graph. In our example, we could substitute the OVIS probe response time in place of the OVPA client data.

44

Editing Existing Graphs

Edit a graph in PerfView by first drawing it, then use the menu items on the graph itself to adjust its metrics, visual settings, etc. Select File / Save, enter a unique graph name and optionally a description. You cannot save a graph with the same name as a predefined graph.

To edit a graph in OVPM:

Go to the Design tab and click on the Open icon.

Select the graph you want to edit; it will then be loaded in to the user interface. Treat this graph just like one you created using the OVPM user interface directly. Make whatever changes you desire, preview the graph, etc.

When you are finished, press the Save button to save it back under the same name or the Save As button to save it under a new name.

If you attempt to Save over a predefined graph, you will automatically enter the Save As dialog to select a different graph.

Graphs must be unique within a Family so you can have graphs with the same name so long as they are in the different families. Normal users will be prevented from modifying graphs in the predefined graph families in any way.

45

Adding Metrics to an Existing Graph

Once a graph is drawn in PerfView, select menu item Settings/Change Graph Metrics to enter a dialog that allows metrics to be added or deleted from the existing graph. Save the graph using the menu item File/Save otherwise the edits are temporary.

46

OVPM separates the generation and editing of graphs from the display of pre-defined graphs. This is to keep things simple for casual users. If you want to add and delete metrics to a graph, you should draw the graph using the OVPM Design tab. Select the graph you want to start with using the Open button. Select the System or Systems using the Sources tab. Press Preview to draw the graph.

To add or remove metrics from the graph, select the Metrics tab in the Design screen and add/delete graphs as you normally would to create a graph. Press the Preview button when you are finished.

You may also use this procedure to change any other attributes in the graph such as those found in PerfViews Settings/Change Visual Effects menu item.

Save the graph using the Save As button otherwise the edits are temporary.

47

Managing Lists of Systems

PerfView keeps track of which systems have performance agents through its PerfView Systems dialog. Systems may be assigned to groups for easier location through this same mechanism. Any user can add systems to the list of managed systems for PerfView.

OVPM can get a list of data sources in a variety of ways. The OpenView Reporter product discovers a list of systems running performance agents. It assigns those systems into groups for better manageability. If OVPM is configured to use the Reporter database, it will use the Reporter system and group lists.

The OVPM system administrator can enter a list of systems and groups into simple text files (systemsMWA.txt and systemsCODA.txt) to handle cases where Reporter is not present or it is present but does not include all the systems that OVPM should use. Instructions for editing these configuration files are provided in the OVPM Administrators Guide.

Normal users cannot make permanent changes to the list of systems using the web interface of OVPM. A Web user can temporarily add a system for their own use provided they know the system name (a name which can be used to locate the system in the network) and the type of performance agent it is running (OVPA, OVOA). When the user terminates their session with OVPM, these temporary system names are discarded.

If the PerfView product was installed and systems and groups were entered into it, then there is a migration procedure to transform the PerfView systems and groups into OVPM Systems.txt configuration files. See the PerfView Migration Guide (PVMigrate.htm) for details.

48

Migrating from PerfView to OVPM You have some choices if you are already using PerfView (or OVPM version 3 or earlier) and are now migrating to OVPM version 5.

1. Install OVPM 5 and start to use it independently of PerfView. Work with the predefined graphs to determine how well they meet your needs. Use Reporter to provide a list of systems, or edit the Systems*.txt configuration files. Continue to use PerfView until you are comfortable with using OVPM and your end users have migrated to the new interface.

2. Install OVPM 5 and migrate your existing PerfView graphs, systems and groups into OVPM. Use the PVMigrate tool included with OVPM to assist in this task. The documentation for PVMigrate can be located in:

OVPM on Windows at http://localhost/hpov_help/PM/C/PVMigrate.htm

OVPM on HP-UX and Solaris at /opt/OV/paperdocs/PM/C/PVMigrate.pdf

3. Discontinue using PerfView as soon as you are comfortable to more fully utilize the features of the new version of OVPM.

49

Programmatic and Scripting Interfaces PerfView runs as an executable program and produces output as x-window displays, Tiff image files, PostScript and ASCII files. You access PerfView by executing the pv command or running /opt/perf/bin/pv and passing parameters.

OVPM runs as a web application. It is implemented as a web service. You run it by invoking a URL request to the web server on the system where it is installed and it produces web pages. Those web pages can be displayed in a web browser or other application that supports similar functionality. OVPM can produce ASCII and XML output files and as a part of its web page it produces GIF or PNG image files and HTML.

If you translate this to mean that you may have to adjust any programmatic running of PerfView in order to work with OVPM, I suspect that you are right.

Luckily, interfaces to other OpenView products like OpenView Operations, Internet Services and Reporter are already done for you. If you have an application that can present a web page, then you will probably find that OVPM is fairly easy to use and very powerful. In an initial survey of how customers were using programmatic access to PerfView, we found out the following:

Many customers run PerfView in batch mode with the PostScript or TIFF files in order to get the graphs onto an end-user web page. [Good News, with OVPM, most of this superstructure can be swept away since OVPM is already a web application.]

Some customers run PerfView in order to export a file that they can process and load into a word processing document. [More good news. OVPM graphs are available as interactive Java Graphs, PLUS they are also available as GIF or PNG files in HTML web pages. To copy an OVPM graph to a word processor, simply cut and paste the image from a web browser and youre done. Background batch operations can, with only a little assistance, locate the image files for these HTML web pages so they can process them using scripts.]

Some customers run PerfView to export raw data into spreadsheet or ASCII format so they can reprocess it and turn it into something of their own design. OVPM can do this, but the syntax may be different (CSV, TSV, XML, and excel output formats). Some adjustment to processing scripts will probably be required.

Examine the online help pages for OVPM, but especially the OVPM Administrators Guide. Both documents are available when you install OVPM.

Whats New with OV Performance Manager 5.0? OV Performance Manager 5.0 (OVPM) is a brand new technology that provides more flexibility and more features to all aspects of OpenViews graphing product. It is the only product that allows you to combine information on-demand from different data sources in a single graph. While the previous graphers only supported OV Performance Agent (OVPA), the latest OVPM supports OVPA as well as the OV Operations Agent Embedded Performance Component (OVOA-EPC), OV Internet Services and OV Reporter.

OVPM 4.0 Supports the Latest Technologies... Datacomm: OVPM supports DCE and NCS based datacomm, as well as the new

firewall-friendly BBC datacomm used by the latest OpenView products. Its important to know that previous versions of our grapher do not support BBC. Consequently, these older graphers do not support connections to OVOA-EPC, as well as OVPA 4.0 on Linux.

Web: OVPM utilizes a web server that allows the user interface to be web-based and virtually platform independent, accessible from anywhere with network access to OVPM. This accessibility is not without security. OVPM has the ability to restrict access based on IP or machine name. When used with Internet Services or Reporter, their customer security is preserved when using OVPM.

Java: Java technology has allowed us to provide a more flexible user interface, as well as interactive graph output. It requires a Java plug-in that is automatically downloaded by OVPM at initial invocation of the Java user interface, or drawing of a Java graph. The Java UI allows per-metric filtering, more control over the look and feel of the graph and metric display, and provides Complex Graphs (graphs data from multiple data source types). The Java graph is highly interactive. You can change metric properties like line color, metric label. You can turn data markers on or off, toggle metrics on or off, and fix scaling by aligning some metrics to a second Y-axis. If you dont like the graph displayed as a line graph, you can change it to a bar, stacked bar, or area graph. You can also adjust the display to better see the data by using the 3-D rotate, or the Zoom to spread out data points. If you are working over a slow network connection, or do not want to download the plug-in, a pure HTML UI is available, called the Web Forms interface. The Web Forms UI is not as robust as the Java UI, but is faster to load and may be faster to navigate for some users. An HTML graph type is also available which provides a GIF or PNG image in a static web page; it is well suited for incorporating into other web pages or documents.

51

OVPM 5.0 Supports more Options for Output The latest OVPM supports all the major output types from earlier versions, as well as some new ones:

HTML web pages and image files

XML, an evolving standard for data exchange

CSV, Comma Separated Values for import into other tools

TSV, Tab Separated Values for printing and import into other tools

Excel Spreadsheet (when using a Microsoft Client with Excel installed)

Consult the Administrators Guide for details.

We support the same table and graph type output as previous versions, and also support new graph types including:

Gauge graph: useful for monitoring a single metric across several systems. Combined with auto-refresh, can be used as a dashboard.

Bar graph: some graphs are better represented with side-by-side bars rather than the traditional line graph.

Baseline graph: a powerful graph that takes all available data from the specified data source and shows you whats normal for a typical week. Following the typical week, the output is broken down to each typical day and compares it to actual data for that day last week. This quickly shows you if the system or application is performing outside of its norm.

52

OVPM 5.0 Enables Complex Analysis Complex analysis is enabled in OVPM by a couple of different features. One is its drill down feature, available with the Java graph. Drill down allows you to drill down to table details, as well as to another graph. A common use case is to regularly draw a Global History graph that visualizes the most important aspects of a system. If an anomaly is discovered, say with CPU utilization, you can drill down at a point in time to a CPU Summary or other CPU-focused graph. From here, you can drill down again, perhaps into a Process Details table. Analysis is not limited to out-of-the-box graphs. From the design interface, its easy to create new graphs and tables tailored to your environment. Once saved, your custom graphs are generically available to use against all systems.

The Complex Graph is another graph type that allows you to combine metrics from different data sources in a single graph. In the world of services and Service Level Management, it is increasingly difficult to manage system performance in isolation from the rest of your environment. Take, for example, a web services environment. Web site performance can be affected by web server and web application server performance, database processing, and of course, is dependent on the performance of the system it is running on. Businesses that rely on their web sites being well managed often use OV Internet Services to tell them when certain web services, like html and ftp, are performing below defined Service Level Objectives. OpenView also provides a suite of SPIs to help manage your web and application environment. For example, OVPMs Complex Graphs allow you to graph OVIS Response Times, with Web Application SPI Transaction Throughput, alongside OVPA CPU utilization. You can see how this single view would allow you to isolate the source of the problem at a glance. You then have the option to drill down again within a specific data source, depending on which is showing the problem.

53

OVPM 5.0 Integrates with Other OpenView Products

with OV Reporter

In addition to being a data source, Reporter enables other functionality when paired with OVPM. OVPM will automatically use Reporters list of discovered systems, even as Reporter adds new systems to the list. (You can add a system manually if you dont want to wait for Reporters discovery cycle.) Additionally, Groups defined in Reporter are automatically available to OVPM. By default, it groups by agent and operating system. User-defined groups created from Reporter also become available in OVPM. If Reporter has customers configured, OVPM can present its graphs with customer-specific data. It is possible to configure OVPM so that different customers can use it to view their own systems, but not systems from other customers.

with OVIS

When OVPM is configured to use the OVIS databases, it can present its graphs with customer-specific data. Customers, passwords and services are configured from OVIS. As with Reporter, when launching either OVPM interface, you have the option of logging in with a customer login and password.

with OV Operations

The latest OV Operations has a contributed integration with OVPM that allows the operator to launch a graph in context from the message browser. See the OVO documentation for details.

See the OVPM Administrators Guide for details on these integrations.
