Measuring CPU performance from the CommandLine using PerfMon
In a previous post, I talked about viewing "coarse grained CPU performance" of an application using Process Explorer. It's a great way of checking "at a glance" how a process is performing CPU wise. However, if you want to get down with the nitty-gritty details of your server's performance, you need to bring out the big guns and use the built-in perfmon utility. I don't know why, but I always find perfmon fiddly to use. Maybe it's just me! Anyway, in this post I just wanted to describe the batch-file I use to test a server's health. As you know, you can drive perfmon from the GUI by running the perfmon.exe command from the start menu. When you do, you will be presented with this screen: To get started, first use the logman create command to setup the perflog. In the instance below I have named the log "ocean_airdrop_log" and assigned 2 counters to it. logman create counter ocean_airdrop_log -c "\Processor(_Total)\% Pro
