Issue/Introduction

UMA agent Memory Usage metric data is showing all most the double size of the actual usage that is showing on GCP. 

Before upgrade of the UMA agent the metric data was showing perfectly, as per the GCP .

However after upgrade, the AIOPS matrices data has increased around 40%-50% . Where as on GCP its showing the same usage as it was showing before upgrade.

Environment

Release : 21.3

Component : Introscope

Resolution

This is not a defect. For GKE monitoring there are some changes made in recent UMA agent release. We have added a new metric "Memory working set" which will match with the value coming in GKE.
