I’ve recently had a ton of requests for information about specific VMs. They want to know how many disks they have, CPU count, how much RAM, and which environment the VM resides in.
Instead of constantly searching vCenter, I wrote this quickly during the meeting to query multiple servers.

I hard-coded my vcenter hostname in there, so you’ll need to change that line
|
1 |
connect-viserver vcentername > $NULL 2>&1 |
Usage is like this:
|
1 |
Get-VMInfo.ps1 servername |
or
|
1 |
Get-VMInfo.ps1 ("server1","server2","server3") |
And expected output is like this:
Server Server1
OS is Red Hat Enterprise Linux 4 (32-bit)
Running on host esxihost1 in the cluster1 cluster in the vdatacentername Datacenter
It has 1 virtual disks, 1 CPUs, and 2 GB of RAM
Not real sophisticated, but works…
Hi Luke, the script is brilliant, thanks!
On the other hand I was thinking, if you can export details to CSV file which can give little more info related to the VMs.
VMname, VMhost, Cluster, Datacenter, vCPU, MEM, GuestOS, Disk1 Datastore, Disk1 Path, Disk1 Size…. DiskX Datastores, DiskX Path, DiskX size, VMNIC1 Mac, VMNIC1 Port group, VMNICX Mac, VMNICX Port group, Notes.
This would give all the required info to the requester.
I agree, I could go a lot deeper with it and export to CSV. I wrote this just to fill a quick void while I was in a meeting and need quick info on one VM here and there.
