Re: [monit] Only monitor processes with present PID files?

[Martin Pala]

You can use "mode manual" statement which doesn't enable monitoring until you 
want to. You can then hook "/usr/bin/monit monitor apache" to your rc script 
past apache startup, so it monit will start to watch service when rc script 
finished.
