As admins one of the things we need to be able to prove is the stability and reliability of our systems. With Windows 7 and Windows 2008 R2 we have a way to do this

function get-stabilityindex {
[CmdletBinding()] param ( [parameter(ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)] [string]$computer="." ) Get-WmiObject -Class Win32_ReliabilityStabilityMetrics ` -ComputerName $computer | select @{N="TimeGenerated"; E={$_.ConvertToDatetime($_.TimeGenerated)}}, SystemStabilityIndex } |
Use the Win32_ReliabilityStabilityMetrics class – see http://msdn.microsoft.com/en-us/library/ee706632(VS.85).aspx for details
The function takes a computer name and returns the date and time a metric was computed and its value.
We’ll follow this up with a look at Win32_Reliability records next time
