[Mulgara-dev] Monitoring resource use

[Alex Hall]

Does anybody have any insight into the topic of monitoring resource usage of a
Mulgara server?  The idea is, once we put up a publicly available,
Mulgara-backed website that incorporates the ability to execute SPARQL queries,
we expose ourselves to denial-of-service attacks.  The sort of thing that I
would be interested in doing is some sort of throttling or rate control;
assigning different priorities to queries; and monitoring queries to either kill
or lower the priority of ones that are running too long.  One possible approach
would be to extend MBean capability to the Session level (right now there is an
MBean interface for the server object) but I'm sure there are others.  I'd love
to hear back from anybody with experience or thoughts on this topic.

Regards,
Alex
