Restrictions And Limitations - Cisco BTS 10200 Troubleshooting Manual

Call Tracer (CTRAC)

Restrictions and Limitations

This feature is available only to users with both CLI and root (UNIX) access.
Note
Due to implementation limitations, it is possible that some per-call related TRACE logs may not have
CTRAC-IDs. Such occurrences however are limited in number.
The CCB shared memory used by various modules is affected. The CCB structure to is expanded include
CTRAC-ID.
Operating
The CTRAC feature is the key enabling feature for the end user interested in troubleshooting or
debugging calls by viewing the BTS 10200 trace logs. CTRAC enables the system user to collect all BTS
10200 trace logs pertaining to a single call. Please refer to the following sections for examples of using
the BTS 10200 CTRAC feature:

Isolating Calls Based on Billing Record
To isolate calls based on the billing record, take the following steps:
For a given call of interest, note (through CLI) the value of the CTRAC-ID billing record parameter. This
Step 1
value is the CTRAC-ID for the call. For this example, assume that it is M0000001. The CTRAC
billing-cdr parameter is CTRACID. It can be obtained by using the CLI report billing-record command.
For each call-processing platform of interest (CA, FSPTC, FSAIN, BDMS), go to the directory where
Step 2
the BTS 10200 trace logs are stored (by default this is the
/opt/OptiCall/<platform-instance-name>/bin/logs directory).
If the trace log files are gzip'ed by the platform, you have to copy the gzip'ed files to a separate directory
Note
and perform the necessary operations to unzip the file in the separate directory.
$ cd /opt/OptiCall/<platform-instance-name>/bin/logs
Where platform-instance-name could be CA146, FSPTC235, or the name of some other platform
installed in your system.
In the directory where the BTS 10200 trace logs are available, use the UNIX grep command to filter out
Step 3
the trace logs corresponding to the selected CTRAC-ID.
$ grep "M0000001" *.log
View the CTRAC-M0000001.txt file with a text editor to browse the trace log file lines corresponding
Step 4
to the call.
