VMware ESX – Health Check KB Article

Firstly, I have to give full credit to Duncan over at Yellow Bricks for drawing my attention to this VMware KB article from his blog posting here.

If you find that your ESX server is displaying one of the following symptoms:

• The ESX host seems slow
• There are a lot of errors in the log files
• Accessing the ESX host over a SSH session is slow 
• Operations performed on the ESX host time out

… Then as part of the problem diagnosis process you will want to check the usual 4 core areas:

• Disk Space
• CPU
• Memory
• Network 

This VMware KB article gives good basic ‘starting place’ type information on how to check each of these potential problem areas on your ESX system which will hopefully assist in a speedy recovery.
