Hi,
Memory field/column for few of VMs in our ovirt (Compute -> Virtual Machines ->
Memory column) shows more than 90%.
But, when I checked (from free and also other commands) the actual "used" memory
by those VMs, it is less than 60%. What I see (from free -h) is that ovirt seems to be
considering both "used" + "buff/cache" memory and is reporting the
same in GUI.
Isn't it the "available" memory that should be considered, because that is
the actual memory available and cache memory is something that is adjusted every time?
:~> free -h
total used free shared buff/cache available
Mem: 15Gi 6.8Gi 724Mi 310Mi 8.1Gi 9.2Gi
Swap: 0B 0B 0B
Can someone help to answer. Thanks !
