Checking VCSA performance using vimtop

Monitoring the performance of your VCSA is a critical part of managing your virtual environment. If your VCSA is not performing well, vSphere admins will experience lag in vSphere Web Client and system processes, such as vMotion, HA, and DRS, will not perform as well as expected.

In this recipe, we'll check the performance of your VCSA using vimtop.

Getting ready

To step through this recipe you must have a running VCSA and an SSH Client (Putty). No other prerequisites are required.

How to do it...

1. Open the VCSA CLI in Putty.
2. Log in as the root with the root password.
3. Once logged in, you will be presented with the Command prompt.
4. Type shell and hit Enter. This will launch Bash and get you to a # prompt.
