Question by Peter M. · Aug 17, 2012 at 09:59 PM ·

Is it possible to use dynaTrace for Hung Thread Detection?

This question came up recently - is it possible to use dynaTrace to detect hung threads - threads consuming excessive CPU or not terminating after some amount of time?

I expect that the solution would require us to look for PurePaths which have not completed after some length of time, and alert on them?

Every method in the PurePath has thread wait or "wait" as a state. You will see this in a large way if you look at response time hot spots. You can also make sure these thread are just hung and not blocked by created a thread dump. We saw this condition the other day where the thread was hung and JBoss timeout was set to 0 which is the null value.
