[OSGeo-Discuss] Geenral question about pinging a service for "aliveness" . . .

[Tyler Mitchell (OSGeo)]

You might also want to take a peek at how Nagios does it's monitoring - I'm sure there are a few good examples in there, if not a whole package you could tweak.  
I used it a long time back...  http://nagios.org/
