ASAP 2.5 Database history new features

− ASAP can now automatically maintain long term history

− Days, Weeks, Months, or even Years can be kept using the following SET option

SET DBMaxDays [<entity>] <days>

• DBMaxDays option controls both− Amount of History for all entities− Variable history for each entity


ASAP 2.5 Database – SET DBMaxDays

− SET DBMaxDays [<entity>] <days>

− Examples

SET DBMaxDays 1 ! History for all entities, 1 day SET DBMaxDays Cpu 365 ! History for Cpu entity, 365

days SET DBMaxDays PCB 60 ! History for Process Busy, 60

days SET DBMaxDays Disk 30 ! History for Disk entity, 30

days SET DBMaxDays File 14 ! History for File entity, 14 days


ASAP 2.5 Database – SET DB…subvol

− SET DBRolloverSubvolPrefix defines subvolume prefix

− Example• SET DBRolloverSubvolPrefix ASAP ! Subvol prefix = “ASAP”

− Rollover files are named using following filename template:− $DATA.ASAPyyyy.ZmmddEEE

Where:<prefix> defines 1..4 alphanumeric character prefix, eg ASAPyyyy - year rollover occurred, such as 2004mm - month rollover occurred, such as 12dd - day rollover occurred, such as 31EEE - three letter entity acronym, eg Cpu, Dsk, Exp, ...

− Cpu stats file for 2004, December 31 would be named− $DATA.ASAP2004.Z1231CPU


ASAP 2.5 Database – DB command

− DB command provides analysis of historical database

DB [ <year> ] [ INFO ] [ DETAIL ] [ <entity> ]

• <year> indicates year to analyze• DB command alone provides disk usage by entity and by

date. • INFO provides file info about DB files: last-mod, owner,

rwep, …• DETAIL provides first and last record timestamps for each

file• <entity> allows you to restrict analysis to one entity

ASAP 2.5 Communication line Monitoring

• Auto-Discovery of the supported Communication line types (Default).

• The COMM SGP supports individual user defined Comm line monitoring.

• Monitor command syntax:

• MONITOR entity [ \ node. ] domain [ ,ADD/ON [ ,OFF ] ]• entity

is the name of an ASAP entity as defined in EDL (COMM).• node

is the node name the Command applies to.• domain

is any form of an ASAP domain name. Domain names can represent physical devices ($X25A).

• ADD/ON

turns monitoring on in the database for the specified domains in the specified entity.• OFF

turns monitoring off in the database for the specified domain in the specified entity.

• MONITOR COMM $SNAX• MONITOR COMM $X25a

• MONITOR COMM !Displays Comm lines added to the DB

• MONITOR COMM, LIST !Displays Comm !lines

being !monitored by !the Comm SGP


ASAP 2.5 COMM SGP Discrete Objectives Thresholds (DOTS)

The ASAP user can configure Discrete Objectives Thresholds for the COMM SGP.

Objectives may be configured on the following DOTs Attributes:

Cpu Primary Cpu number of the Comm Process for this line Bcpu Backup Cpu number of the Comm Process Requests Comm line IO requests per second Busy Percent Time Line Busy reading, & writing Readbusy Percent Time Line Busy Reading Writebusy Percent Time Line Busy Writing Inkb Input Kilobytes per second Outkb Output Kilobytes per second Indatakb Data Kilobytes read per second Outdatakb Data Kilobytes written per second Rate Total of reads, writes per second Reads Number of read operations per second Writes Number of write operations per second Retries Number of I/O retries Transactions Number of terminal transactions all subdevices on the line Resptime "Response time per terminal transaction


ASAP 2.5 COMM SGP DOTs (Continued)

• Use the ASAP CI “RANK” command for configuring individual DOTs attributes.

• Rank Comm, Busy > 60 • Rank Comm $X25A,Busy > 30

• Rank Comm !displays Comm Attr !added to the

DB

• Rank Comm, list !displays the Attrs that !the Comm Sgp is !reporting on.


ASAP 2.5 Configuring the ASAP Comm SGP The ASAP CI Communication configuration

options for the set command are:

− ON|OFF ON enables network-wide COMM status reporting. OFF disables network-wide COMM status reporting.

The default value is OFF.

− OBJECT Defines the <ASAP COMM program object filename>. This program will be started on each node by the ASAP monitor.

The default is $SYSTEM.SYSTEM.ASAPCMM.

− CPU Defines the CPU the COMM Sgp will reside in.

− PARAMETERS Specifies the COMM specific parameter string to be passed to the ASAPCMM process at startup time.

The default is the <null> string.

The Parameter list must be enclosed in double quotes .


ASAP 2.5 Configuring the ASAP Communication SGP (Cont)

The <COMM-param> options are:

CPU <cpu num> Defines the Cpu where the MEASFH process will reside.

NOMEAS Prevents COMM performance statistics from being collected. COMM state information, and Config will be collected during each sample period.

RATE <minutes> Defines the interval, in minutes, that COMM statistics reported back to the Collector . The default is the ASAP RATE.

SUBVOL <subvolume> Specifies the subvol location of the Measure Data file

SWAPVOL [<$volume>] Specifies the location for the Measfh swap volume. The default is $SYSTEM.

VOLUME [<$volume>][.][<subvolume>] Specifies the location of the Measure Data file. The default is $SYSTEM.SYSTEM

This is an example of the SET COMM command:

+SET COMM ON, OBJECT $SYSTEM.ASAP.ASAPCMM, PARAMETERS "VOLUME $DATA.ASAP RATE 10", CPU 3


ASAP 2.5 ASAP CI “COMM” COMMAND

The COMM command displays communication statistics for the specified <nodes>.

The Comm command options are:−Samples Number of Comm Samples displayed for monitored Comm lines.

ASAP 2.5 Comm SGP Performance Statistics (Cont)

INFO displays the following:

D.xx NonStop Kernel displays the following:− STATE State of the device.− LDEV The logical device number of the Comm line.− PIN Process identification number of the primary process.− TYPE The Device type and the subtype of the Comm line.− CTRL Controller address (in Octal) that the device was

using.− UNIT Unit number of the Comm line.− CH Channel that the Comm line was using.− PROGRAM The Comm lines object file name.− G.xx NonStop Kernel displays the following:− STATE State of the device.− LDEV The logical device number of the Comm line.− PIN Process identification number of the primary process.− TYPE The Device type and the subtype of the Comm line.− GRP Group number that the device was using.− MOD Module number of the Comm line.− SLOT Slot number of the Comm line.− PROGRAM The Comm lines object file name.


ASAP 2.5 CI Command Status Enhancements.

STATUS TIMEOUT ENHANCEMENT−ASAP 2.5 now allows a user timeout value for the status

command. The timeout value is in seconds. The Default is 15 seconds.

−Timeout values are in the range of 1 to 99 seconds.−STATUS Timeout 5

Each SGP has 5 seconds to respond to the Status request. Any error 40 will be displayed for each SGP exceeding the timeout value.

Other STATUS Enhancements:−ASAP 2.5 now displays any SGP that did not start as an error 11 in

the Status output.−When an SGP is not working properly and is stopping the ASAP

Monitor will wait 15 minutes before attempting to restart the SGP. The first attempt to start the SGP could be longer than 15 minutes depending on the time the Monitor was started. This check is done during the 15 minute audit interval.


ASAP 2.5 SGP CPU Placement

ASAP 2.5 now supports user specified CPU placement for all SGPS.

− CPU placement is achieved by using the set <sgp> command. CPU is a new option supported by all ASAP 2.5 SGPs.

− CPU validation for CPU number 0-15 are performed. In the event the CPU is unavailable the SGP will be started in the same CPU as the ASAP Monitor process.

− SET PROCESS CPU 5− SET SPOOLER CPU 6


ASAP 2.5 Additional SGP Enhancements

• Disk SGP now allows thresholds to be set against the disk attribute “FRAGMENT”.

Rank Disk, Fragment < 200

• The ASAP DISK SGP now allows the ASAP user to specify decimal values for setting disk queue length objectives.

Rank Disk $System, Queue > .5

• The ASAP DISK SGP now supports the Enterprise Storage Subsystem, subtype 52 disk devices.

• Both the ASAP CPU SGP, and System SGP now allows thresholds to be set against the total number of debug breakpoints that are in use.

Rank CPU, BrkPnt > 2
