[cas-dev] application monitoring

[J. David Beutel]

Yes, it looks generic (i.e., complicated) and requires a Hyperic server, 
which will take resources (JBoss + database), although it's FOSS (for 
the non-enterprise edition).

The local Hyperic agent can monitor JVMs via JMX, like JConsole/VisualVM 
can, but through the Hyperic server to record in the database and view.  
Also, it has app-specific plugins, e.g., for Tomcat, which can provide 
app-specific stats and auto-discovery.  So, a CAS-monitoring plugin for 
Hyperic seems possible, especially if you are already running a Hyperic 
server.

However, I'm still just trying out Hyperic, so I don't know yet if I'd 
recommend it for this kind of monitoring.
