Does anyone have a good reporting tool so that I can see for example, all VM:s with its allocated memory and used memory?
I know I can use the built in function (rigth click on host->report performance), but you can only see on or the other...
Which good tools are out there?
Try looking for Hyper9 it is a good product. Let me tell you, after they were purchased by Solar Winds their support has gone very bad. I feel you are preety much on your own.
