    Cluster IOPs chart

    ahowell

      Hi,

      I'm charting IOPs per cluster and have noticed that the figures for the cluster don't seem to match the figures for individual hosts or datastores

       

      Choosing a point in time as an example

       

      Cluster IOPS 116/s

      Datastore 1 IOPS 117/s

      Datastore 2 IOPS 151/s

      Datastore 3 IOPS 231/s

       

      Also if I show IOPs for one of the cluster hosts I get different values depending on how I add it.

       

      If I add it by clicking on the show component values, then I get a value of 84.5 IOPs, but if I add by just adding a new line I get a value of 159 IOPs

       

      Interestingly if you add all the 'show component values' hosts together you do get the result it reports for the cluster.

       

      Can you please explain this. I was using these cluster figures for monthly reporting, but now I can't trust the figures.
