Configuration of java hung thread

[manish_bachu]

How can i configure the alert for the java hung thread in DT? I dont see any option in custom alert as well.

Per default there is no metric for hung threads.

But uou could add a "hung threads" metric via a JMX Plugin.

thanks patrick.

While uploading the pulgin under custon plugin, i hope we have to select "One Agent Plugin" right not the "Activegate plugin"

[pahofmann]

Correct it is a OneAgent Plugin

Hello @Patrick H. @Julius L. @Sebastian K.

I added the following JMX metrics, and since that time, I can see that there is a constant number 6 for all of them.

Do you think that I did some mistakes while adding metrics?

Can you check the values using jconsole or jmxterm?

I don't know if this is still an issue for you but I found that using the "average" aggregation gave me the correct values for declared hung and concurrent hung in my dashboard tiles. Hope that helps!

Hello,

There's no such metric in DT.

You can create an alert based on Websphere Log.

You could have this kind of error :

WSVR0605W:
Thread “WebContainer : 1” has been active for 612,000 milliseconds and
may be hung. There are 3 threads in total in the server that may be
hung.
