Today - I was trying to "catchup on" (and cleanup) my downloaded podcasts. I heard Show 81 with Shawn Creamer from Microsoft on Performance Monitoring and it spoke about a Technet article by Steven Choy also from Microsoft. They referred to it as a PDF but the link is the Technet article.
Shane Creamer stressed that people need to learn how to use the performance monitoring tools, and the article identifies the 25 most important counters that developers and IT staff need to be aware of. This information is something that I will want to come back to and feel that others would find of great interest also. Shane teaches a course on Performance monitoring to pinpoint issues.
The RunAsRadio did post a video on the site that goes with the Show 81 - but did not put sound that came from the show which dramatically lessened its value.
RunAsRadio also had an interview (Show 77)with Steven Choy who speaks about performance monitoring and virtualization. Both shows were good. and I would recommend given them a listen.
