Hi to all. I've been working with GenericJMX jvm plugin (current master version in git --collectd 5.4.1--) and I've tested with hotSpot jdk , jrockit from oracle and j9vm from IBM.
And collectd - GenericJMX - Always reconnects when JVM process restart.. no need to restart collectd. Best Regards 2014-09-25 18:40 GMT+02:00 Rahul Agarwal <[email protected]>: > Thanks Bryan.
