I was talking through the data collection (default) intervals with one of our VMware architects earlier this week. This is what I told him:
VMAN polls every 10 minutes via the vSphere API
Data is collected in 10 second blocks for the entire period (60 blocks by default)
Data presented via the console is the peak value, average value, etc. for the 10 minute period.
"Wait a second," said the architect, "if the data is an average can you show me the standard deviation for that 10 minute period along with the average and peak?"
"Uhhh... maybe?"
Does anyone know if this is possible? Is the standard deviation stored anywhere for us to display in a graph or report?
