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.
