Hang diagnostics 2.0 are out for ASP.NET apps!
This was a major rewrite of the diagnostic algorithm, and a complete redesign of the interface.
Some of the biggest changes:
1. Visualize IIS/ASP.NET execution flow
. This is basically a pretty diagram showing exactly where requests were executing during the hang, and how the IIS & ASP.NET engines were performing. Really helps understand where the hang was taking place and who was the blame.
2. Better diagnostic insight
We’ll identify things like threadpool exhaustion, concurrency issues, server resource exhaustion, and give best practices on how to fix the hang given these findings. So the stuff that you’d normally pay someone thousands of dollars to tell you.
3. Support for Classic ASP apps
Because we cannot analyze threads for Classic ASP scripts, we leverage script-level trace data to identify the functions/SQL queries that the ASP script is hanging on. Pretty cool stuff and usually spot on for most Classic ASP hangs.
More about the new hang diagnostics
The interface is really sleek as well, you can see/search all blocked requests, broken into the areas causing blocking, and see the app code/modules that caused the slowdown.
There are also a number of advanced features that I’ll write about shortly, including being able to perform advanced debugging actions for hangs.
