[ovs-discuss] Question about "--monitor" option

ovs-vswitchd and ovsdb-server both support the --monitor option. According
to the man page, --monitor creates an additional monitoring-process to
monitor the daemon.

How do we monitor the health of the monitoring-process itself? What if it
crashes?

Since there is no PID file configuration for the monitoring-process, it is
not possible to fetch its PID (short of parsing the ps output). This makes
monitoring the monitoring-process using a tool like Monit challenging.

Has anyone figured out a clean way to detect failure/crash of the
monitoring-process and restart it, or some way to configure the PID file
location?

Thanks!
