Today’s post will be a shorter one, feeling a little sick this week. To start off there’s esxtop which is a command line performance monitoring utility for ESXi, one disadvantage is that it can only be used directly on the host you are monitoring performance on. That is where resxtop comes in, remote esxtop, or resxtop, allows you to monitor ESXi performance remotely from the command line. So, resxtop can be run remotely while esxtop can only be ran from the ESXi shell. Then there is vimtop which allows you to monitor vCenter performance. These tools are very complicated and I will not be able to get into much detail in this post. This was just a brief overview on what these tools are.
