number of headers greater than value
Is there a way to find all web requests with the number of headers greater than say 30? If so how to get the headers?

Thanks Andi. We will upgrade in few weeks and checkout the options.
Hi
Thats an interesting one. Well - there is the option to capture all HTTP Headers but there is no option to then do a count on it. Also - it would capture a lot of information that you never look at.
With dynaTrace 6 - just released - I see an interesting option. In dynaTrace 6 you can instrument a method that gets e.g. HttpServletRequest object - maybe you instrument a specific Servlet Filter method that is always called. Now - instead of capturing that request object you can now leverage "Deep Object Access". In the case of HttpServletRequest you can make a call to getHeaderNames().size() to capture the size of that list that comes back. Not sure if this works exaclty with that call as getHeaderNames returns an Enumerator which doesnt provide a size method - but - I guess you get the options that you now have with deep object access.
Once this argument is captured you can create a regular Method Argument Measure to extract that number. you can use this measure as a filter on a BT to get those PurePaths (=Web Requests) that return a number larger than 30
