Tracing PGCP Operations

You can trace the following PGCP operations and record them in a log file:

all—All PGCP operations
configuration—Configuration events
debug—Debug messages
error—Error messages
gate—Gate request and reply events
media-function—Media function events
pgc-connection—PGC connection events
pgcp-stack-debug—PGCP stack debug events
pgcp-stack-h248—H.248 messages between VPGs and PGCs
pgcp-stack-trace—PGCP stack function call events
routing-socket—Routing-socket events
trace—Process function calls

All log files are placed in the /var/log directory. When a trace file reaches its maximum size, a .0 is appended to the file name, then a new file is created with a .1 appended, and so on. When the maximum number of trace files is reached, the oldest trace file is overwritten.

Step-by-Step Procedure

To configure tracing of PGCP operations:

Access the PGCP traceoptions configuration.[edit] user@host# edit services pgcp traceoptions [edit services pgcp traceoptions]
Specify a name for the trace file. [edit services pgcp traceoptions] user@host# set file pgcp
Set the maximum number of trace files. If you specify a maximum number of files, you also must specify a maximum file size.[edit services pgcp traceoptions] user@host# set files 10
Specify the operations that you want to include in the log file. For example:[edit services pgcp traceoptions] user@host# set flag gate user@host# set flag pgc-connection user@host# set flag pgcp-stack-h248
Prevent any user from reading the log file.[edit services pgcp traceoptions] user@host# set no-world-readable
Allow any user to read the log file.[edit services pgcp traceoptions] user@host# set world-readable
