This post is about monitoring resource usage of a list of virtual machines hosted on VMware ESXi clusters using PowerCLI. Output format is given below which gets refreshed automatically every few seconds.
Prerequisites:
- VMware.PowerCLI module should be installed on the node from which you are running the script
- You can verify using: Get-Module -Name VMware.PowerCLI -ListAvailable
- If not installed, you can find the latest version from the PSGallery: Find-Module -Name VMware.PowerCLI
- Install the module: Install-Module -Name VMware.PowerCLI
Note:
- I am using PowerCLI Version 11.0.0.10380590
Latest version of the project and code available at: github.com/vineethac/vmware_vm_monitor
Sample screenshot of output:
Notes:
VMware guidance: CPU Ready time and Co-Stop values per core greater than 5% and 3% respectively could be a performance concern.
Hope this will be useful for resource monitoring as well as right sizing of VMs. Cheers!
