Hi Experts;

When we check Middle Tier Server performances using GRAFANA dashboards to check POD wise CPU & Memory utilization , below were observed

Dashboard used :

Even under normal conditions, some PODs have ‘MEMORY REQUESTS ~ MEMORY LIMITS’ as in above image.

QUESTION :-

Does that mean these pods are fully utilized [memory] even under normal conditions ?
Here MEMORY USAGE is always higher than MEMORY REQUESTS & MEMORY LIMITS.Is that a cumulative value or else?
Should we mention that as a concern to consider when we give recommendations/ suggestions based on these details/behavior.

Hi @Dilshan Aththanayake,

Memory Request - defined value which the pod reserve for him self

Memory Limit - max value of memory which can be used.

To your Questions:

Memory Usage is the value what the pod is really using;
Strange that in your example Memory Usage > Memory Limit. Theoreticaly should not be allowed to be used more as the limit. I would say, this is a indication to start more ifsapp-odata pods.
Yes
