Process Monitoring
Significant events of the sysmgr are stored in /tmp/sysmgr.log. The log is a wrapping buffer and is useful
for troubleshooting. Use the show processes aborts location node-id all command or the show sysmgr
trace verbose | include PROC_ABORT command to display an overview of abnormally terminated
processes.
Because the sysmgr is already monitoring all processes on the system it is not necessarily required to
monitor vital processes by external management tools. But, you can use the show fault manager metric
process pid location node-id command to check critical processes on a regular basis (for example, twice
each day). The command output provides information including the abort behavior and the reason of the
particular process.
The following example shows OSPF critical process details. Check the number of times the process
ended abnormally and the number of abnormal ends within the past time periods.
