Re: [EXTERNAL] Restart apps based on total system CPU usage

[Mike D]

Hey Lutz,

I know specifically what app I would like to restart so your solution looks like it may help me.

Thanks,

Mike

check system $HOST
  every 5 cycles
#  if loadavg (1min) > 4 then alert
#  if loadavg (5min) > 2 then alert
  if cpu usage > 95% for 10 cycles then alert
  if memory usage > 95% for 20 cycles then alert

The problem is, to find the right application. But this works well, as
long as you know the application.

  if cpu usage > 95% for 10 cycles then exec "/usr/local/bin/monit
restart given_app"

This is the reason Mark use a script to find this application and I use
a script to find the application that use the storage.

But you can check a specific application also, see
