How to install VisualEsxtop

If you haven’t already heard, VisualEsxtop is a Fling developed by a few VMware Engineers that provides a java based GUI to the every useful ESXTOP. As an added bonus provides a description of each counter, multiple windows, the ability to sort metrics, and even provide basic graphs. Oh and it’s FREE!

Setup and install on Windows 7 is pretty easy as well:

I’ve been using VisualEsxtop for the last month or two now and have been impressed with it for sure. The only issue I have with it is that I can’t remove items from the chart view once I’ve added them, otherwise it’s been working great. Check it out!
