# Overview
|
|
|
|
|
|
|
|
The script generally accepts a vCenter hostname and list of servers on which to correct the CPU settings. Not providing a list of servers to correct will run a read-only pass on the vCenter and output all servers on which the script could/would alter the settings.

|
|
|
|
|
|
Examine and apply changes to three servers using VMCO rules:

|
`.\FixBadSockets.ps1 -VIServer vcenter.partners.org -VMCOLogic -Specific server1,serverB,serverIII`
|
|
|
|
|
|
|
|
Examine powered-off VMs and produce a CSV report of suggestions:
|
|
|
|
|
|
