This idea relates to this Esri Community thread: Understanding Java heap behavior
To gain a full and accurate understanding of memory utilization in ArcGIS Enterprise, I would like to see ArcGIS Monitor expose Java heap specific metrics such as heap utilized/committed, heap consumption per service, max heap, and garbage collection behavior.
Adding Java heap and GC metrics to ArcGIS Monitor would significantly improve troubleshooting, memory management and tuning, and overall visibility into ArcGIS Enterprise health and performance.
