Using TypePerf to get performance data on the command prompt.
I was tracking a high CPU issue this week and needed to know when one of my servers was pegged so I could investigate. I could of used perfmon I guess but I really like to do everything I can from the command prompt. I always like it when there is a tool that can do data collection from the command prompt as this gives you the ability to easily script it if warranted.

C:\Windows\system32>typeperf "\\Server1\Processor(_Total)\% Processor Time"
"(PDH-CSV 4.0)","\\Server1\Processor(_Total)\% Processor Time"
"09/20/2007 15:42:42.926","18.097697"
"09/20/2007 15:42:43.928","21.217785"
"09/20/2007 15:42:44.929","15.757631"
"09/20/2007 15:42:45.931","16.537653"
The command completed successfully.
You can collect any counter that lives in the perfmon world, I'm sure some of you out there will find a use for this.
C:\Debuggers>typeperf "\\serverX\Server\Server Sessions" -sc 2
"(PDH-CSV 4.0)","\\serverX\Server\Server Sessions"
"09/22/2007 13:21:54.110","8.000000"
"09/22/2007 13:21:55.117","8.000000"
The command completed successfully.
Full Syntax below, you can adjust the collection in numerous ways.
