Hi Thomas,

I was thinking the same thing with other resources too, like the EJBs, JMS queues, etc.

In our company we use RHQ to monitor production JBoss servers with a lot of EJBs but no one is really interested to monitor these EJBs or at least they are interested in monitoring only some of them.
These useless resources bring unnecessary load on both RHQ server and agent. By default they are checked for the availability and have some metrics enabled.

An idea would be to have a lazy discovery for these resources - at request, maybe some configuration in the Connection Settings of the parent resource to enable the discovery of such child resources, maybe define a regexp pattern for the resource names we are interested in.


Regards,
Costel

Subiect: AS7 plugin: Hibernate Query Cache resource type

Hi everyone,

I fixed "Bug 1033130 - [AS7] Exception during discovery of Query Cache
resources of RHQ Server resource" this week.

So what? Well now if you inventory RHQ server resource you get more than
2000 query cache resources showing up. Which of course costs you CPU and
memory.

You can of course just ignore this resource type (via the admin pages).

So I was wondering: shouldn't we change such resource types to no longer
auto discover them but only allow manual add?

Opinions?

Thanks,
Thomas
