Checking for cron

[jmarquart at planalytics.com]

or - if already running ssh - you can do:

checkcommand:
     define command{
          command_name   check_remote_procs
          command_line        $USER1$/check_by_ssh -H $HOSTADDRESS$
/path/to/host/checks/check_procs -c $ARG1$ -w $ARG2$ -u $ARG3$ -C $ARG4$
     }

and then a service:

     define service{
          use            your-favorite-template
          host_name      host.to.check
          service_description CROND proc
          check_command  check_remote_procs!1:50!1:20!root!crond
     }

and then you can check your process using the plugins - and securely.

Nagios_statd from http://www.twoevils.org/html/files.php will do the trick.

Write a plugin to basically do "ps -ef | grep cron | grep -v grep" and if
the answer is null, return a critical error "exit 2".  Then call it remotely
using NRPE from your Nagios host.

But this begs the question... are you seriously having problems with cron
abending?

If I were you, I'd be checking logfiles and/or running truss and/or checking
with SunSolve.  If you're still not having any luck, try and install xinetd.
But seriously, I'd consider cron to be one of those daemons that never
exits, unless someone's been mucking with the libraries (or the binary, for
that matter).
