Re: Restart in chek file

[Martin Pala]

Hello Sergey,

the restart action for the file service calls stop->start programs with no 
delay - in comparison the process check waits for the process to stop, as monit 
knows the PID of the process which should terminate.

=> in your case the apache didn't start because when the start script was 
called, the stop was still in progress (in parallel).


It will be better to modify the configuration like this (delegate the process 
restart to standalone process check):

--8<--
check process apache with pidfile /var/run/httpd.pid
   start program = "/etc/init.d/httpd start"
   stop program = "/etc/init.d/httpd stop"

check file error_log with path /var/log/httpd/error_log
   start program = "/bin/bash -c '/usr/bin/monit restart apache'"
   if match 'signal Segmentation fault' then restart
   if match 'exit signal Aborted' then restart
   if match 'server reached MaxClients setting' then restart
   if 5 restarts within 10 cycles then exec "/bin/bash -c '/usr/bin/monit 
unmonitor error_log && /bin/sleep 3600 && /usr/bin/monit monitor error_log'"
--8<--

Regards,
Martin
