vCenter Performance Counters over time - average resource usage or point in time?

This should be fairly easy, but I'm having trouble locating this on the VMware website.

I'm using the Performance Reports feature in vCenter 4 to measure gather data about an ESX Server over the last year. When I choose this time range for the report, it comes back with CPU, Memory, Disk, etc usage for every day during that period at 12:00:00.

My question - is this a point in time capture for midnight each day, or is the average data for that day? Makes abig difference in analysis.

Thank you!

That is not a point in time capture, it's an average. The statistics are rolledup.

You should be able to confirm, this by looking back at your actual statistics, in the last few days, and check them, e.g. CPU at 12.00, 1st October 2010, check that against the Yearly Graphs, and you'll see the related CPU and Usage figures are less in  the yearly summary, than the actual figures recored at that time.
