Today I was asked to gather a list of all VMs within a given cluster and report on their disk usage (all the VMs are thick provisioned) and currently do not have a tool to perform a seemly simple task. After some searching I have found many versions of this script around the internet but none that quite suited me needs. I have modified about 50% of the original script to suit my needs and added these features.
- Prompts for vCenter hostname or IP
- Requires user to select a cluster
- Queries vCenter for list of cluster names (for use above)
- Limits results to specified cluster
- Prompts for output filename
- Default saves to current user’s Documents folder
- Prints location of filename
- Auto launches file once complete
I should also mention that I am not a script writer. My abilities exist in finding, understanding (most of the time), and modifying existing Powershell scripts. I will be unable to assist with drastic modifications to any script.
Requirements: VMware PowerCLI, vCenter Credentials with appropriate permissions
How to run: Save below script to .ps1 format and run from PowerCLI. No need to modify anything to make compatible with your environment.
