Tracing the SBC Configuration Process

You can trace the following SBC configuration process events and record trace results in a log file:

• common
• configuration
• device monitor
• IPC
• memory pool
• user interface

All log files are placed in the /var/log directory. When a trace file reaches its maximum size, a .0 is appended to the filename, 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.

To configure tracing of the SBC configuration process:

1. Access the traceoptions configuration.
   [edit]user@host# edit system processes sbc-configuration-process traceoptions[edit system processes sbc-configuration-process traceoptions]
2. Access the traceoptions trace file configuration.
   [edit system processes sbc-configuration-process traceoptions]user@host# edit file[edit system processes sbc-configuration-process traceoptions file]
3. Specify a name for the trace file.
   [edit system processes sbc-configuration-process traceoptions file]user@host# set filename sbc-config-trace
4. Set the maximum number of trace files.
   [edit system processes sbc-configuration-process traceoptions file]user@host# set files 10
5. Set user access to the trace log file. Use set no-world-readable to prevent users from accessing the log file, or use set world-reabable to allow any user to read the log file.
   [edit system processes sbc-configuration-process traceoptions file]user@host# set no-world-readable
6. Access the traceoptions flag configuration to define trace level options.
   [edit system processes sbc-configuration-process traceoptions file]user@host# up[edit system processes sbc-configuration-process traceoptions]user@host# edit flag
7. Set trace level options for the components of the SBC configuration process that you want to trace. For example:
   [edit system processes sbc-configuration-process traceoptions flag]user@host# set common debug[edit system processes sbc-configuration-process traceoptions flag]user@host# set configuration debug[edit system processes sbc-configuration-process traceoptions flag]user@host# set memory-pool debug
