memory

I've done some searching, but can't seem to find a way to do this.

We'd like to proactively monitor our permgen space via JMX. It seems the best way to do this is through the UsageThreshold attribute on the "PS Perm Gen" MemoryPool. By default, this is set to 0. Is there a way to specify this, or any JMX attribute, as a -D parameter to VM so this can be set automatically at startup? Or is there another mechanism to load JMX attributes automatically?

Thanks.
