How to get the stack traces for the thread counts we see against the JVM?

[i306171]

Dear Team,

Against the JVM node, we received a high thread count alert, in Dynatrace, we do see that the JVM thread count went up to 15k. Is there a way to go back and check what each thread was doing? Can Dynatrace take the stack trace snapshot for all 15k?

Let us know if something needs to be configured.

If Dynatrace already has the stack trace details then let us know where to refer to.

Thanks

There is a CPU profiling/Thread Analysis feature described here:

Most thread groups will let you drill down into the overall "Method Hotspots" view that gives you the stack trace details you're looking for.
