SystemEDGE not reporting accurate memory utilization within CAPM
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.
