script to output hyper threading settings to a csv file??

[golddiggie]

Looking for a script that will run against all hosts in a vCenter server and output the hyper threading settings to a csv file.

Specifically looking for state of:

UserVars.SupressHyperthreadwarning

VMkernel.Boot.hyperthreading

VMkernel.Boot.HyperthreadingMitigation

I'm sure it's probably an easy thing for those who have done a lot more with PowerShell/PowerCLI.  :smileywink:

Try like this

Get-VMHost |

Select Name,

@{N = 'UserVars.SuppressHyperthreadWarning'; E = { (Get-AdvancedSetting -Entity $_ -Name 'UserVars.SuppressHyperthreadWarning').Value } },

@{N = 'VMkernel.Boot.hyperthreading'; E = { (Get-AdvancedSetting -Entity $_ -Name 'VMkernel.Boot.hyperthreading').Value } },

@{N = 'VMkernel.Boot.HyperthreadingMitigation'; E = { (Get-AdvancedSetting -Entity $_ -Name 'VMkernel.Boot.HyperthreadingMitigation').Value } } |

Export-Csv -Path .\report.csv -NoTypeInformation -UseCulture

Thanks LucD... As always, quick to come up with a working solution to what's requested. Now we have a way to get the list...

One quick question... Is there an easy way to have the report.csv file name have the vCenter name in it (at the start)?? That way if it's decided to run this through automation, we can have the report named correctly and not have them write over each other. :smileywink:

Sure, something like this?

$reportName = ".\HT-report-$($global:DefaultVIServer.Name).csv"

Get-VMHost |

Select Name,

@{N = 'UserVars.SuppressHyperthreadWarning'; E = { (Get-AdvancedSetting -Entity $_ -Name 'UserVars.SuppressHyperthreadWarning').Value } },

@{N = 'VMkernel.Boot.hyperthreading'; E = { (Get-AdvancedSetting -Entity $_ -Name 'VMkernel.Boot.hyperthreading').Value } },

@{N = 'VMkernel.Boot.HyperthreadingMitigation'; E = { (Get-AdvancedSetting -Entity $_ -Name 'VMkernel.Boot.HyperthreadingMitigation').Value } } |

Export-Csv -Path $reportName -NoTypeInformation -UseCulture

Perfect... :smileyhappy:
