Issue/Introduction

  • I have configured the cdm probe to send an alarm when memory usage exceeds 90% but when stress testing the server no alarm is sent even though memory usage is 97%

Cause

  • When configuring cdm via Infrastructure Manager there are 3 categories for memory monitoring
    • M: allows you to specify the threshold values for total memory usage.
    • S: allows you to specify the threshold values for swap memory usage.
    • P: allows you to specify the threshold values for physical memory usage.
  • These are selected by the buttons on the memory chart
  • The probe was configured to monitor total memory usage (M) which monitors pagefile rather than Physical memory usage (P)
  • Whilst physical memory usage was 97% the total memory usage was only 85%

Environment

Release: CNMSPP99000-8.4-Unified Infrastructure Mgmt-Server Pack-- On Prem
