Has anybody here tried the "Monit" utility (http://mmonit.com/monit/)? I
need to set up some kind of "watchdog" functionality for a custom
service otherwise started via init (i.e. via a script in /etc/init.d +
rc*.d links managed by chkconfig) and it seems like this system may give
me nearly what I want. However, something that concerns me about it, is
that it appears to take full ownership of the services it monitors, and
pretty much bypass the init system, in that once I've told monit to
watch a process, it makes not difference if the associated service is
enabled or not (via "chkconfig") , and there is no good way to fully
stop the service, besides removing the Monit config or disabling Monit
itself. (Or maybe I can use special "monit" commands, too, but that
means precisely that Monit "owns" the service, which I somehow don't
quite like.)
What I'd really like, is to have my process watched and restarted if it
goes a way, but only if it had already been started via "init" or
through the "service" command, or possibly direct execution of the
"init.d" script. This also means it should be restarted if it crashes or
if is stopped via a direct "kill", but not after "service <name> stop"
or similar. Which might mean it all boils down to checking if, and only
if, the pid file for the service already exists. (Does that make any
sense?)
So, does anyone know if there is a way to convince Monit to do this for
me? Or alternatively, is there a different tool that might do the job?
And yes, I know it shouldn't be that hard to design a
program/script/cron job to do it all for me, but I still think not
having to maintain another software component would be nice...
