cron script to verify application is running?

Llwyd · 12-20-2002, 05:56 PM

Is there a built in device to verify an application is running, and if it is not running, to spit out an error to syslog or better yet restart it? I have a business critical app that dropped on me the other night and didn't run over the weekend.

If there isn't a built in device can anyone point me in the right direction on how I would go about scripting something like this?

Thanks in advance,

is something as basic as

Code:

if [ `pidof -s applicationnamehere` ]
then
  echo application is running already
else
  echo application not found, loading now
  applicationnamehere
fi

suitable?

Hmm, thanks for the input, but I just stopped the app and ran the check and it still said it was running.

Lookup "monit" at Freshmeat. It can do different kind of checks, pids, ports, sockets.
