Performance Counters? There’s a script for that.

It’s not hard to get Performance Monitor counters in PowerShell 1.0, and it’s REALLY easy in 2.0. This is one I used yesterday to monitor network bytes in and out on 2.0 (keep all of the green lines in this post on the same line) :

get-counter -Counter "\Network Interface(*)\Bytes Total/sec" -SampleInterval 1 -MaxSamples 10


The –SampleInterval is in seconds, and the –MaxSamples sets how many you want. The –Counter parameter is the object and counter you want to monitor. Don’t know what they are for your system? No problem:

get-counter -ListSet *


Need to hit another computer? Easy Peasy – doesn’t even require remoting to be turned on (but you do need to have the rights to hit the perf counters):

get-counter -ComputerName COLLOSSUS -Counter "\Network Interface(*)\Bytes Total/sec" -SampleInterval 1 -MaxSamples 10


If your machine happens not to be named “COLLOSSUS”, just change that part J. And yes, you can use whatever counters you like, including SQL Server locks, blocks, etc. The full reference for get-counter is here:
