Get VM Cluster Name, Host Name, CPU and Cores

[AGFlora]

HI

All of the following code is yielding the desired results except the last line. I can't seem to get it to work. What am I doing wrong?

Get-VM | Select Name, @{N="Cluster";E={Get-Cluster -VM $_}},

                           @{N= "ESX Host";E={Get-VMHost -VM $_}},

                           @{N= "NumCPU";E={Get-VMHost -VM $_ | Select NumCPU}},

                           @{N= "Cores";E={Get-VMHost -VM $_ | Get-View).Hardware.CpuInfo.NumCpuCores}}

Thanks!

There was a missing ( in front of your last Get-VMHost. You also just want the attribute NumCPU, not an object containing one attribute NumCPU so I've changed line 3 a little

Get-VM | Select Name, @{N="Cluster";E={Get-Cluster -VM $_}},

    @{N= "ESX Host";E={Get-VMHost -VM $_}},

    @{N= "NumCPU";E={(Get-VMHost -VM $_).NumCPU}},

    @{N= "Cores";E={(Get-VMHost -VM $_ | Get-View).Hardware.CpuInfo.NumCpuCores}}

If you're running this for a large # of VMs you may want to look at optimizing it a bit. Rather than calling "Get-VMHost" multiple times you can restructure a bit so its only called once

Get-VM | Select Name, @{N="Cluster";E={Get-Cluster -VM $_}},

    @{N= "ESX Host";E={ $Script:VMH = (Get-VMHost -VM $_ ); $Script:VMH.Name }},

    @{N= "NumCPU";E={$Script:VMH.NumCPU}},

    @{N= "Cores";E={$Script:VMH.ExtensionData.Hardware.CpuInfo.NumCpuCores}}

The 2nd piece of code is a little over 2x faster than the first since Get-VMHost isn't being called multiple times

One other quick thing, if you're looking for the number of CPUs (i.e. how many sockets) then replace $Script:VMH.NumCPU with $Script:VMH.ExtensionData.Hardware.CpuInfo.NumCpuPackages; the NumCPU attribute of the host object is actually the number of cores so that can be a bit misleading

Thanks Craig! Exactly what I was looking for and more.

One more question if I may?

How can I add the VMHost count?

Thanks

[Craig_Baltzer]

$Results = Get-VM | Select Name, @{N="Cluster";E={Get-Cluster -VM $_}},

    @{N= "ESX Host";E={ $Script:VMH = (Get-VMHost -VM $_ ); $Script:VMH.Name }},

    @{N= "NumCPU";E={$Script:VMH.NumCPU}},

    @{N= "Cores";E={$Script:VMH.ExtensionData.Hardware.CpuInfo.NumCpuCores}}

# VM to host

$Results

# hosts per cluster (count)

$Results | Select-Object Cluster, "ESX Host" -Unique | Group-Object Cluster -NoElement | Select-Object @{N="Cluster"; E={$_.Name}}, @{N="NumHosts"; E={$_.Count}}

# total hosts

"Total Hosts: " + ($Results | Select-Object "ESX Host" -Unique | Measure-Object).Count

How would you pipe this all to a csv file?

[Craig_Baltzer]

Each line in a CSV file needs to have the same fields, and you're dealing with three types of data (VM data, a host rollup, and a summation) so the fields aren't the same. What are you planning to do with the CSV file? There may be another format that could be used...

[AGFlora]

I need to send this as a report. Your first answer worked and I was able to export all the data to a csv file. Now they want the vmhost cluster count in the report as well.

Thanks for your quick response.

[Craig_Baltzer]

You could do something similar to this (replace C:\reports with your preferred reports directory). You'll end up with 2 files that you can then import into whatever you're using to format your reports.

$Results = Get-VM | Select Name, @{N="Cluster";E={Get-Cluster -VM $_}},

    @{N= "ESX Host";E={ $Script:VMH = (Get-VMHost -VM $_ ); $Script:VMH.Name }},

    @{N= "NumCPU";E={$Script:VMH.NumCPU}},

    @{N= "Cores";E={$Script:VMH.ExtensionData.Hardware.CpuInfo.NumCpuCores}}

# VM to host

$Results | Export-CSV -NoTypeInformation -Path "C:\Reports\VMs.csv"

# hosts per cluster (count)

$Results | Select-Object Cluster, "ESX Host" -Unique | Group-Object Cluster -NoElement | Select-Object @{N="Cluster"; E={$_.Name}}, @{N="NumHosts"; E={$_.Count}} | Export-CSV -NoTypeInformation -Path "C:\Reports\HostsByCluster.csv"

I was hoping to have all the data in one file but oh well.

Thanks again for your help!
