Are people still using PSSDiag?

If you have ever worked with Microsoft support, you probably came across the PssDiag tool they use to collect information about your environment.  My experience with the tool is it always seemed, well–a bit clunky.  Now, it does collect lots of information and seemed to be a bit overwhelming when I was first a DBA.  Fast forward a few years and PssDiag was not a tool I use anymore and was not sure if anyone outside of Microsoft was using it.  I run into Jared Poche in Raleigh and he mentions he really likes the tool and mentions some of the improvements they have made over the years.  Well, you can guess where this is heading.

We talk with Jared about his experience with the tool and cover some of the basics about how you might go about using this tool in your environment.  There are two pieces to this tool, the first is the utility that collects the data and the second is the reporting piece SQL Nexus.
