Re: [monit] monitor multiple processes

[Martin Pala]

Hi,

if they have common parent process, you can watch it and use the  
totalmem and totalcpu (since monit-5.0) for monitoring the total  
resource usage. If you want to watch the resource usage of each  
particular process, you'll need separate pidfiles (note that we plan  
to add support for process monitoring without the pidfile in the  
future).
