Re: Conditional check process?

[Martin Pala]

You can use independent file test which will control the process monitoring, 
something like:

--8<--
check process sidekiq_1 with pidfile /tmp/pids/sidekiq_1.pid
   start program = "/bin/bash -l -c 'bundle exec sidekiqctl start" as uid jim 
and gid jim with timeout 250 seconds
   stop program = "/bin/bash -l -c 'bundle exec sidekiqctl stop" as uid jim and 
gid jim with timeout 120 seconds
   if cpu usage > 25% for 18 cycles then restart
   if mem > 1500.0 MB for 18 cycles then restart

check file sidekiq_control with path /tmp/do_not_start_sidekiq.txt
    if does not exist then exec "/usr/bin/monit start sidekiq_1" else exec 
"/usr/bin/monit stop sidekiq_1"
--8<--

Regards,
Martin
