Retrieve VM Information in VMware vSphere
This post details a PowerShell script designed to retrieve and display vital information about virtual machines (VMs) in a VMware vSphere environment. By automating this process, you can easily monitor VM configurations and performance.
### Step 1: Connect to vCenter Server
To interact with your VMware environment, youll first need to connect to the vCenter Server using the `Connect-VIServer` cmdlet. This step establishes the necessary session.
1 2 3 4 5 6 | # Define vCenter Server details$vcServer = "vcenter_server_IP_or_FQDN"$vcUser = "username"$vcPassword = "password"# Connect to the vCenter ServerConnect-VIServer -Server $vcServer -User $vcUser -Password $vcPassword |
### Step 2: Get the List of Virtual Machines
Here, you will gather a list of the VMs in the vCenter environment using the `Get-VM` cmdlet. This command retrieves all active VMs, which will be processed in the subsequent steps.
1 2 | # Retrieve all virtual machines$vms = Get-VM |
### Step 3: Display VM Information
With the list of VMs ready, the next step is to iterate through each VM and display relevant information such as name, power state, and CPU/memory details.
1 2 3 4 5 6 7 8 | # Display information for each VMforeach ($vm in $vms) { Write-Host "VM Name: $($vm.Name)" Write-Host "Power State: $($vm.PowerState)" Write-Host "CPU Count: $($vm.NumCpu)" Write-Host "Memory Size (MB): $($vm.MemoryMB)" Write-Host "-------------------------------------"} |
### Step 4: Disconnect from vCenter Server
Finally, after gathering and displaying the VM information, its important to disconnect from the vCenter Server to maintain good session hygiene.
1 2 | # Disconnect from the vCenter ServerDisconnect-VIServer -Server $vcServer -Confirm:$false |
