How to Monitor Java Threadpool Count (Similar to /ui/apps/dynatrace.classic.profiling/ui/diagnostictools/PROCESS_GROUP_INSTANCE-XX

[michelsantos10]

Hello,

I need guidance on how to monitor and visualize the number of threads in a Java threadpool directly within Dynatrace. Ideally, I would like to achieve something similar to the Threadpool Count information displayed at the following path:

/ui/apps/dynatrace.classic.profiling/ui/diagnostictools/PROCESS_GROUP_INSTANCE-XXXX

This type of metric is critical for identifying performance bottlenecks and ensuring the health of Java applications.

Could someone please guide me on how to implement this? Is there a native way to achieve it, or would it require custom metrics or additional configurations?

Thank you for your assistance!

hi @michelsantos10, 

We have the inbuilt metrics to get the Thread count for the process level.

If this is not the one you are looking then, please check the Extensions which can be used as per the technology such as Tomcat, Weblogic, WebSphere or any other JVM based setups.

If none of this gives you the expected solution, you can use the Custom JMX extension to build your own. And the only thing you should know is, MBean package and the metric.
