However, just because a metric is available, doesn't make it available in the interval you'd like. I find the most informative method is to see what sampling intervals are available by using <code>Get-StatInterval</code>, and then query for 5 samples of each metric... | |||

A couple of final points to note | |||
* To retrieve data for the Realtime interval, use the <code> -Realtime </code> option, not <code> -IntervalSecs 20 </code> | |||
** All metrics at this interval are averages | |||
* Virtual Centre generally drops metrics during roll-ups etc (subject to configuration), therefore for the fullest range of metrics, check with the ESX direct (though only 20sec and 300sec intervals are available). | |||
** I'd suggest always trying to go via the Virtual Centre, but the data you're after isn't available, check with the ESX direct. | |||
