function Get-VMInfo { <# .SYNOPSIS Get-VMInfo The Get-VMInfo function gathers Virtual Machine (VM) information such as Name, Hostname, Number of CPUs, Power State, Memory Size, IP Address, Creation Date, VLAN ID, Used Disk Space, Disk Size, Operating System, Folder Location and Cluster Name from multiple vCenters using PowerCLI module. .DESCRIPTION This function takes a string array of multiple hostnames or partial names. To use this function, you must install the PowerCLI module and provide credentials for the vCenters. This function can be used with multiple vCenters and multiple VMs. It also supports pipeline input. .EXAMPLE Get-VMInfo -VirtualMachines "server1", "server2" -VCenters "vc1" -Credential $cred This command gets the information for VMs "server1" and "server2" from the vCenter "vc1" using the credential $cred. .EXAMPLE vm1, vm2, vm3, vm4 | Get-VMInfo -VCenters "vc1" -Credential $cred This command gets the information for VMs vm1, vm2, vm3, and vm4 from the vCenter "vc1" using the credential $cred. .EXAMPLE Get-VMInfo -VirtualMachines "server1", "server2" -VCenters "vc1", "vc2" -Credential $cred This command gets the information for VMs "server1" and "server2" from the vCenters "vc1" and "vc2" using the credential $cred. .EXAMPLE vm1, vm2, vm3, vm4 | Get-VMInfo -VCenters "vc1", "vc2" -Credential $cred This command gets the information for VMs vm1, vm2, vm3, and vm4 from the vCenters "vc1" and "vc2" using the credential $cred .PARAMETER VirtualMachines The list of Virtual Machines to get information for. Accepts string arrays. Get-VMInfo -VirtualMachines "server1", "server2" vm1, vm2, vm3, vm4 | Get-VMInfo .PARAMETER VCenters The vCenter name or IP address to connect to. Accepts a string. Get-VMInfo vm1, vm2 -VCenter "vc1" .INPUTS String[] .OUTPUTS Custom Object with VM information.

If VMware tools are not up to date or are not installed, this function will return the virtual machine name and the outdated tools version. For this function to work properly, VMware PowerCLI module needs to be installed. .EXAMPLE Get-VMTools -VirtualMachine Luis-VM01 This example gets the VMware tools status for the virtual machine named "Luis-VM01". .EXAMPLE Get-VM | Get-VMTools This example gets all virtual machines and then checks the VMware tools status on each virtual machine. .INPUTS The function accepts an array of strings that specifies one or more virtual machine names. .OUTPUTS The function returns virtual machine name and VMware tools version installed. .NOTES This function requires VMware PowerCLI module to be installed. The function also leverages PowerCLI’s Connect-VIServer cmdlet to connect to the vCenter server. Prompts the user to enter the vCenter server credentials. .ROLE This script checks the VMware tools status on one or more virtual machines. .FUNCTIONALITY This function checks the VMware tools status on one or more virtual machines. .LINK This script is a custom function created by Luis Carrillo.
