A Wandering Mind

I just wanted to post this quickly before I somehow lost the syntax I developed. What I was trying to do is gather some PerfMon counters for a set period of time and return some aggregated (averaged) results. Here’s what I ended up with:

$counters = (Get-Counter -ListSet "LogicalDisk");
$counterValues = ($counters.PathsWithInstances | Where {$_ -like "*Sec/*"} | get-counter -MaxSamples 10 | select -ExpandProperty CounterSamples);
$groupedValues = $counterValues | select Path,InstanceName,CookedValue,Timestamp | Group-Object Path;
$avgValues = $groupedValues | % {New-Object PSObject -Property @{CounterName = $_.Name; AvgValue = ($_.Group | Measure-Object CookedValue -Average).Average}};
$avgValues | Out-GridView;

This ends up working really well for what I needed. Now I just need to wrap it in a function, parameterize it, and enable it to interrogate remote machines via PowerShell remoting (less firewall hassles that way).
