vCOPS documentation is not really good and information is scattered all over the place. It would be really nice, if VMware does justice to this product and puts in more resources for documentation.
It is very hard to understand all the metrics that are in “All Metrics” tab under “Operations” tab, when you click on a VM. After some research, I found few nice links – which explains few of those counters. I will keep on adding them as I find.
Hope this helps, when we are trying to decipher those cryptic counters.
