Hi guys, I understand how to monitor long running processes with monit or god, but I don''t understand how to monitor Cron jobs (for memory bloating notably) since such processes - always have different PIDs when they start - are precisely supposed to stop when they are done, then restart when asked (vs running all the time). I have been looking on the web for a while, but didn''t find any simple way. Is there a recommended "basic strategy" to monitor Cron jobs? Thanks!

When the process starts, or when it is started by a wrapper, the process writes it''s pid to a file such as /var/run/my_app.pid As the pid is always written to the same file monit can read the file and find the pid of the process and check that there is a process with that pid running. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks Peter. One thing though: my script/runner doesn''t seem to write a PID file (or at least I can''t locate it in the "typical" places - it might be a right issue). Is there a possibility to manually specify a PID file (either a runner option, or a shell command)? I can''t find such option...
