Description Tomas Sykora 2013-09-23 09:04:30 EDT
This bug is related to new JON 3.2.0 ER1 and JDG ER1.

It's not possible to see live cache and cache manager statistics in Monitoring tab for particular resource.

Cache manager statistics tab: "No items to show" 

For caches -- all values are marked as NaN, NaN ms or NaN % even though cache is UP more than 40 minutes.

Refreshing does not help. Get live value button does not help either.

I'm sure that we have entries in the cache and statistics are counted properly. I can see it via CLI console.

Statistics: {
  timeSinceReset: 2966
  stores: 7
  hitRatio: 1.0
  elapsedTime: 2966
  readWriteRatio: 1.2857142857142858
  removeHits: 0
  misses: 0
  statisticsEnabled: true
  averageReadTime: 0
  evictions: 0
  numberOfEntries: 7
  averageWriteTime: 0
  averageRemoveTime: 0
  removeMisses: 0
  hits: 9

A note:

This was tested using rhq-jboss-as-7-plugin-4.4.0.JON312GA.jar because we wanted to test JON 3.2.x but if we are using rhq-jboss-as-7-plugin-4.9.0.JON320ER2.jar with JON 3.2.x and latest jdg server plugin (6.2 ER2) we can't even see at Infinispan resource detected. 

On the other hand, while using rhq-jboss-as-7-plugin-4.4.0.JON312GA.jar we can see 2 Infinispan resources there. (One real, one fake)

This probably deserves another bug...

Renamed for better overview and tracking
Comment 4 Tomas Sykora 2013-11-04 04:40:38 EST
This doesn't need release note for 6.2.BETA release.

William Burns <wburns@redhat.com> made a comment on jira ISPN-3612

This was removed with ISPN-3157.  I need to investigate further why.

After long... long time, I can see changing statistics there finally!
Brilliant fix, thank you!
