CA Performance Management - Usage and Administration DX NetOps

Issue/Introduction

Heap memory usage climbs over time, on both the Data Aggregator and Performance Center

Environment

Dx NetOps Performance Management: 21.2..8 and below

Component : IM Data Aggregator, IM Performance Center, IM Data Collector

Cause

APM agent socket tracing keeps unneeded references to old transaction objects

Resolution

To resolve, there are a few options

  • Upgrade to Performance Management 21.2.9 or higher (DE523480)
  • A workaround for current agents is to disable SocketTracing in core/config/capm-toggles.pbd. (It will result in loss of detailed socket usage metrics).
    • On CAPC, DA, DC edit the following files:
      • PC: /opt/CA/PerformanceCenter/wily/core/config/capm-toggles.pbd
      • DC: /opt/IMDataCollector/wily/core/config/capm-toggles.pbd
      • DA: /opt/IMDataAggregator/wily/core/config/capm-toggles.pbd
  • Add the following to the end of capm-toggles.pbd:
    TurnOff: SocketTracing
  • Stop and Start services CAPC, DA, and DC
