DedcatonsTons of people were a part of making this guide what it is. I personally want to thank each of them.

My family: My wife Christi, and kids Taylor, Brittney, and Nathan for their patience and understanding during this

project. They kept me sane.

Alex Hannah: Whose website I visited before while trying to understand UCCX. His meticulous technical editing

and knowledge guided this project from infancy to maturity. Thank you, Alex.

Section 3 Cisco Unified Serviceability

All alarms have a few options in the drop-down list:

■ Emergency: Designates the system is unusable.

■ Alert: Immediate action is required.

■ Critical: Critical issue.

■ Error: An error exists.

■ Warning: Informational warning message.

■ Notice: Signicant condition, but normal.

■ Informational: Informational messages.

■

Debug: TAC engineers use these for debugging.

TracesThis section is where you configure the traces that can assist you in troubleshooting. They are trace configurations and

troubleshooting traces. You can configure three types of traces: SDI, SDL, and Log4j. The trace configuration option you pick has a

big impact on the information you will receive and how much time you will probably spend during problem resolution. You can see

what type of traces you can configure by checking out Figure 3-2. The files can be viewed in RTMT:

■

Conguration: Congure traces.■ Troubleshooting Trace Settings: Set up predened troubleshooting traces.

You are probably wondering how to choose between a trace and troubleshooting trace. The following table lists the main difference

between these two.



[ 18 ]



Traces Troubleshootn Traces

Minimal information, could missrelevant information

Lots of information, more than is

needed to troubleshoot a specic problem

Apply lters Turns on almost all trace options

Less system impact Major system impact

Trace types include the following:

■ SDI

Runtime events for the related software

IP address

Time stamp

Device name

■ SDL

Call processing from Unied Communications Manager and Cisco CTI Manager Services.

Used by Cisco TAC engineers. Normal administrators provide this information to them only upon request.

■ Log4J

Used for Java applications

Note: Traces affect

system performance,

so use them only for

troubleshooting purposes.

If you want to practice

traces, use a nonproduc-

tion system. In addition,

SDL traces can be more

difficult to read than SDI.

Therefore, you usually

start with SDI traces to

find logs related to CUCM

issues.

FigURE 3-2

Where and How You

Set Up Traces

To configure a trace, follow these steps:

1. Select the server.

2. Select the service group from the drop-down.

3. Select the service.

4. Check the trace boxes you want.

5. Click Save.
