Grouper diagnostics provides a URL on Grouper WS and UI (in 2.2+) which will help to give the health of Grouper. This can include memory in the WS server, connection to the Grouper Registry DB, that sources can perform queries, and that Grouper loader jobs are successfully executing. If everything is ok, a 200 HTTP code will be returned, else 500. A description of the issue will be returned as well. The point is that this URL can by pointed to be web monitoring software like nagioNagios, big brotherBig Brother, BMC, etc.
There is general information displayed on success as well, the server name, number of WS requests (since server started), the last error (if recent), etc.

Trivial option
Use this to do checks often, or when there is a cluster, you can use this on all nodes, and a deeper check on one node only
