SDI Trace

SDI traces are local log files. The IP address, TCP handle, device name or the time stamp can be used when reviewing the SDI trace to monitor the occurrence or the disposition of a request. This device name could be tracked back to the building of the file, which shows the device pool and model. The device pool and model can be tracked back to the building of the configuration file prototype, which will list the network address of the Cisco CallManager(s) and the TCP connection port.

When observing SDI traces, notice that C++ class and routine names are included with most trace lines. Most routines associated with the serving of a particular request include the thread ID in a standard format.

SDI traces will be explained in detail in the case studies in the appendices.

SDI Trace Output

SDI traces generate files (for example, CCM000000000) that store traces of Cisco CallManager activities. These traces provide information about the Cisco CallManager initialization process, registration process, KeepAlive process, call flow, digit analysis, and related devices such as Cisco IP Phones, Gateways, Gatekeepers, and more. This information can help you isolate problems when troubleshooting Cisco CallManager. To properly track the information you
