This happens when there is a resource behind-the-scenes, either in an uninventoried or deleted state. For uninventoried resources the problem should go away when the out-of-band uninventorying is actually performed. *** !!! Test Note : Recreation Step update !!! *** In the recreation steps the problem will only be recreated during a potentially brief period between the uninventory request from the gui and the actual server-side uninventory is performed. Step 3 is actually unnecessary. And you must execute step 4 quickly. There may be other scenarios but I haven't been able to identify them. I thought a deleted (delete, not uninventory) may cause the same problem in a more persistent way, but that did not pan out. Or, perhaps if agents are down. Regardless, the fix should take care of any situation like this. master commit e4e340d418889e7a8972c421fe002a84ff2aa187 Verified on build#231 (Version: 4.1.0-SNAPSHOT Build Number: c4a82bc) Uninventoried the RHQ Agent resource and set the Agent-Server Clock Difference schedule to 29 minutes. No exception is observed. Also verified this when RHQ Agent resource is down. Marking as verified. changing status of VERIFIED BZs for JON 2.4.2 and JON 3.0 to CLOSED/CURRENTRELEASE |
Created attachment 515898 [details] the full stack Making a metric template change, including the existing inventory, can cause Server NPEs and a failed update. To recreate: 1) Import RHQ Agent resource 2) Uninventory RHQ Agent resource 3) Re-Import RHQ Agent resource 4) Try to make a metric template change try setting the Agent-Server Cloxk Difference schedule to 29 minutes This will generate: 10:45:01,362 ERROR [MeasurementScheduleManagerBean] Error updating measurement definitions: java.lang.NullPointerException at org.rhq.enterprise.server.measurement.MeasurementScheduleManagerBean.sendUpdatedSchedulesToAgent(MeasurementScheduleManagerBean.java:830) at org.rhq.enterprise.server.measurement.MeasurementScheduleManagerBean.modifyDefaultCollectionIntervalForMeasurementDefinitions(MeasurementScheduleManagerBean.java:513) at org.rhq.enterprise.server.measurement.MeasurementScheduleManagerBean.modifyDefaultCollectionIntervalForMeasurementDefinitions(MeasurementScheduleManagerBean.java:374) at org.rhq.enterprise.server.measurement.MeasurementScheduleManagerBean.updateDefaultCollectionIntervalForMeasurementDefinitions(MeasurementScheduleManagerBean.java:341) (full stack attached)
