EM 13c: Incorrect Memory Utilization Reported for Linux Hosts in Enterprise Manager 13.1.0.0.0 Cloud Control (Doc ID 2144976.1)

Last updated on NOVEMBER 29, 2017

Applies to:

Enterprise Manager Base Platform - Version 13.1.0.0.0 and later
Information in this document applies to any platform.

Symptoms

Enterprise Manager (EM) 13.1.0.0.0 Cloud Control

Incorrect Memory utilization % is displayed in the Linux x86_64 Target Host's Home page and possible frequent incorrect alerts and emails could be generated for Memory Utilization (%) exceeding thresholds.

The Memory Utilization (%) metric does not consider the Buffers or Cache memory components available for the metric computation.

    


While the total Memory available in the host target is displayed correctly after applying the latest PSU # 23030165 (Agent-Side 13.1.0.0.160429), the formula used for Memory Utilization is (100.0 * (realMem-freeMem) / realMem) and does not consider Buffers / Cached component for the calculation. The formula used by EM  13.1 needs correction.
