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 22.214.171.124.160429), 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.
