Memory Usage under "Home -> Status -> Dashboard"

Description of problem:
eg, login cluster console, select openshift-monitoring project, and go to "Home -> Status -> Dashboard"
from the attached picture, we can see the total Memory Usage is about 3.4G, but from the "Memory Usage by Pod(Top 10)",
we could find prometheus-k8s-0 + prometheus-k8s-1 already exceed 3.4G

search by "pod_name:container_memory_usage_bytes:sum{namespace='openshift-monitoring'} / 1024 /1024" from prometheus UI,
the memeory usage in console UI is about twice the times from prometheus
