I am using QueryPerf to gather stats on VM network usage. My goal is to look at hourly/daily usage.
I am specifically looking at the following stats:
net.received.average
net.transmitted.average
When I have the refresh rate set to the lowest interval for the metric, (20 seconds) I get data back. I get no data back for any other refresh rate.
I seem to recall reading that some performance metrics roll up to regular intervals (5 mins, 15 mins, etc) but can't find clear documentation on if that is true and/or if these metrics are in any such rollup.
If I wanted to track network usage on say, an hourly basis, am I going to have to query the server every 20 seconds? That seems odd. Is there some sort of rollup or other way to accomplish this?
