Error description
Due to de-synchronization of the storage configuration with the Storage Insights tables, the performance collection fails. The performance monitor job logs will show messaging such as the following: HWNPM2133W Performance data could not be collected for device xxxxxx (xxxxxxxxx) due to an unknown error. The current samples are skipped. The following coresponding error is found in the tracePerfMgr*.log files: CollThread87 CollectorThread processCollection DEBUG_MIN Sample pass failed for device xxxx(xxx) [x.x.x.x]. java.lang.NullPointerException at com.ibm.tpc.perf.base.CollLogi cSvc.postProcessCacheStats(CollLogicSvc.java:2078) at com.ibm.tp c.perf.base.CollLogicSvc.processSampPerfData(CollLogicSvc.java:1 091) at com.ibm.tpc.perf.base.CollLogic.performSamplePass(CollLo gic.java:1473) at com.ibm.tpc.perf.base.CollectorThread.recovera bleRun(CollectorThread.java:1553) at com.ibm.tpc.perf.base.PmThr ead.run(PmThread.java:390) _____________________________________ _______________ The defect is against component: 5608TPCSI Device Server Server/Manager build/release: 5.4.0 Problem as described by customer: Missing performance data Initial customer impact (low/med/high): med
Local fix
In some instances it is possible to resume data collection without the ?degraded? status by stopping/restarting the monitoring tasks, stopping both the probe and performance monitor jobs.
