PQ75036: PERFLOAD COUNTER INTEGRAL DECREASING | |||||||||||||||||||||||||||||||||||||||||||||||||
![]() |
|||||||||||||||||||||||||||||||||||||||||||||||||
![]() APAR status Closed as program error. Error description According to the definition, the integral part of PerfLoad counters should be incremental by nature. But sometimes that the integrals of percentUsed and percentMaxed for the top level of " Connection Pools" decrease, i.e. that values for moment T2 is smaller than those for moment T1, while T2 > T1. The problem shows when you set the tperviewer to "View Data As" --> "Change Value" and navigate to Viewer --> YourHost --> server1 --> JDBC Connection Pools.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server 5.0 (Base * * and ND) PMI Users * **************************************************************** * PROBLEM DESCRIPTION: Incorrect connection pool percent used * * PMI metric. The percent used PMI * * metric in Connection Pool module * * doesn't provide correct value. The * * value may be negative at some points. * * The integral portion of the metric is * * not incremental. * **************************************************************** * RECOMMENDATION: * **************************************************************** The calculation of pool size didn't bring the appropriate counters to the current time and hence the integral was negative which leads to a negative average.Problem conclusion The counters that are used to calcuate the pool size are updated to have the same time for integral. The problem is fixed by updating the integral before using it.Temporary fix Comments
