Traces

This 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:

Configuration: Configure traces.
Troubleshooting Trace Settings: Set up predefined troubleshooting traces.

Figure 3-2 Where and How You Set Up Traces

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

Traces	Troubleshooting Traces
Minimal information, could miss relevant information	Lots of information, more than is needed to troubleshoot a specific problem
Apply filters	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 Unified Communications Manager and Cisco CTI Manager Services.

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

NOTE

Traces affect system performance, so use them only for troubleshooting purposes. If you want to practice traces, use a nonproduction 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.
Log4J

Used for Java applications

To configure a trace, follow these steps:

Select the server.
Select the service group from the drop-down.
Select the service.
Check the trace boxes you want.
Click Save.
