Re: [monit] Condition Process Checking?

[Robin Abecasis]

Hi,

Many thanks for your response, but i don't think your configuration quite meets 
my needs. In your example, i would be alerted if process2 OR process3 aren't 
running, correct?

I need to be alerted if process2 AND process3 aren't running. Process1 will 
start either Process2 or Process3, never both at the same time and never 
neither (unless something bad has happpened, hence needing Monit! :) ). Is this 
possible?

Since in my case, neither Process2 or 3 have PID files, i will have to wait 
until your v5.2 release. Is there any documentation of what else will be in the 
v5.2 release?

Thanks again for your response, i look forward to hearing back from you.

Cheers,
Robin
