Trying to understand the metrics below, Why there is huge difference in memory utilization(please refer screenshots) at cluster level and pod level metrics for same pod.
cluster level Grafana metrics:
sum (container_memory_working_set_bytes{pod_name!=“”,node=~“^$Node$”}) by (pod_name)
pod level:
A:
sum by(container_name) (container_memory_working_set_bytes{namespace=“$namespace”,container_name!=“”,container_name=~“$container”,container_name!=“POD”,pod_name=“$pod”})
B:
kube_pod_container_resource_requests_memory_bytes{namespace=“$namespace”,pod=“$pod”,container=~“$container”}
C:
kube_pod_container_resource_limits_memory_bytes{namespace=“$namespace”,pod=“$pod”,container=~“$container”}
thanks in advance
