Hi.
Yes, I understand what you mean. But, in our environment, when I generate a graph for all virtual volumes, parent VVs and snapshots, for a whole day, there are points in time when I see that, for example, the IO operations per second for some snapshot volumes is a great value compared to the mean values for this topic for the rest of the VVs. This means the backup is accessing directly to the snapshot volume data because data at the parent VV have been modified after snapshot creation. In this case, the graphical figure doesn't clearly show the drawing for the rest of the VVs because the figures at the Y axis scale up to the maximum value, nearly "hidding" the lower values. This is, mainly, the reason to separate the reporting between the parent VVs and the snapshot VVs: to see clearly the graphs for both types of VVs.
Anyway, the question has been answered and, as a workaround, I can use, as I already knew, the CLI performance commands to get the performance report data that can be converted to a graph through an spreadsheet application.
Thank you very much for all your explanations.
Regards.
Ana
