I use the open-source monitoring tool http://www.nagios.org/ combined with
NRPE to monitor all my servers and services.

NRPE allows you to connect to the system being monitored, and execute
any command on the local system, returning the result to the Nagios
server. In your case, you could either check for TCP connectivity on
127.0.0.1:10024 or use the check_procs plugin to see if the process is
running -- or both.
This page also contains nice trick to check server against rbl list:

It is also possible to use snmp to monitor, restart or execute (snmp
exec / procfix) commands on remote system:
