This is under the Pod Overview of openshift 3.1.1. What is the Unit of y axis for RAM (what is B?), CPU Shares, and File System (Supposely MB?)?

enter code here On the memory when I click on it, and when it goes to Prometheus, it shows as in the following:

  • "B" means "byte" and RAM is used the binary type unit as multiples of bytes, such as B, KiB, MiB and so on. – Daein Park Aug 09 '20 at 08:37

    @DaeinPark in my case, it means 2 bytes of RAM? But that is not quite possible - I suspect the B should be GB? it makes more sense to me. – william007 Aug 09 '20 at 08:38
  • Usually, the size is too low to run any application as you mentioned, but the "B" unit means "byte" regardless of it. – Daein Park Aug 09 '20 at 08:42
  • @DaeinPark the size is too low to run any application as you mentioned - you mean the given memory size is not accurate? – william007 Aug 09 '20 at 08:44
  • I don't know whether the memory metrics is not correct or not. I mean the size is low usually, but the graph just is shown the value as it is collected. As I remember, the memory usage depends on heapster component of the kubelet on the host which is scheduled the running pod. You may need the real usage from the host. – Daein Park Aug 09 '20 at 08:53
  • I think you need to ask how to check the memory real usage of the pod for comparison with the web console graph usage using other ticket. – Daein Park Aug 09 '20 at 08:55
  • @DaeinPark I think it should be GB, I updated the question with graph in Prometheus - I get to there when I click on the memory graph (show with unit B) in pod overview. – william007 Aug 09 '20 at 08:59
  • @william007 is right, the `B` means billion, hence `GB`. – SYN Aug 16 '20 at 01:04
