Issue/Introduction

  • RHEL server is generating false memory utilization alert as per CAPM even after enabling buffers + cache as part of SystemEDGE free memory calculation.



Environment

Release : 12.9

Component : SEAGTU - SYSTEMEDGE AGENT LINUX / UNIX

Resolution

  • The patch is T6DM043 which is applicable to SystemEDGE 5.9 on RHEL7.x.
  • MemAvailable value was new metric introduced in RHEL7 within cat /proc/meminfo output.
  • This new patch does not use buffers + cached for freemem calculation so you do not want to enable this.
  • Instead It will only look at MemAvailable for the MemInUse calculation:
    memInUse 1.3.6.1.4.1.546.1.1.7.8.9.0
    MemTotal - MemAvailable = MemInUse.
This above calculation is a more accurate representation of true memory usage in RHEL7.
