[AG-TECH] Monitoring of the Access Grid Services

[Jason Bell]

Tom

This is exactly the sort of information I was chasing.

I will let you know how I get on.

Additionally, I will post a doc on the AG website once I have the various tests in place.

Thanks for your feedback.

Cheers,
Jason.

We did this during the AG2 days. Those scripts are still in the SVN repo under tools/nagios, but would need to be rewritten to be useful.

As an alternative for the venue server, you can use the URL test from nagios with the WSDL URL for the server; for example

https://vv3.mcs.anl.gov:8000/VenueServer?WSDL

This will tell you if the SOAP interface is responsive, but will not unfortunately tell you if a VenueClient can successfully enter. Most of the time these two are synonymous, but not always.

For the bridge, you could easily build a good test using the "main" code from the AccessGrid/QuickBridgeClient.py module. This code requests a bridge from the bridge service, raising an exception if it fails. If it succeeds, then it pings the bridge and prints the round-trip time, and then tests the bridge to see if it can receive data from it (return value of 1 is success).
