Issue/Introduction

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

Cause

APM agent socket tracing keeps unneeded references to old transaction objects

Environment

Dx NetOps Performance Management: 21.2..8 and below

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

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
