You're probably best off writing your own shell script that can determine if
a process is running by name (using ps, grep, awk, etc).  Consult the man
pages for those programs for more information.

If you want to take it to the next level, you can use the NET-SNMP agent to
see how many hosts are running on any local or remote machine via SNMP
(you'll need to configure the agent for each specific process) which is
fairly easy to do.  We use this very heavily here.
