Memory utilization alerts started after OEM upgarde

edited Nov 23, 2016 10:20AM in Enterprise Manager Generic (MOSC) 1 comment

Hi Team,

I upgraded the OEM from 12c to 13c and now getting the memory alerts. After search I found that 13c calculated memory in different way as per the below technote.

EM 13c: Frequent Memory Utilization (%) Metric Alerts Observed after Enterprise Manager Cloud Control Upgrade to 13.1 (Doc ID 2150691.1)

My question is how I can calculate this manually to see the diff. from linux box.

As per doc formula used in 13c is..

Formula Used : 100.0 * (realMem-freeMem) / realMem)

12c is

Formula Used : (100.0 * (activeMem) / realMem)

But When I am doing the same thing from linux used, free and total memory I am getting the same result. Can anyone please let me know how I can calculate this outside OEM from linux server to see the diff.

Howdy, Stranger!
