What to monitor: physical and logical disks

- [Instructor] In the last video,…we looked at counters to measure…the server's usage of memory,…and the processor or processors.…I'm going to use the red x up here to remove these counters,…just to clear up the view a little bit…as we prepare to look at how monitoring the hard drives…can help us better understand the server's performance.…Before we look at the counters for our drives,…I do want to throw one piece of information out there,…and this is for those that have been working…with older versions of Windows.…There was a time that the counters…for measuring disk performance…put a big drain on the disk performance,…and they were disabled by default.…

We used to have to run the diskperf command…at the command line to get these counters.…That's no longer necessary.…In fact, if we attempt to run that command,…we'll receive a notice…that these counters are enabled by default.…If you happen to have a legacy application…that needs this specific element,…you can still use the diskperf command…with the Y or N parameters…
