I would like to receive an alert when the number of busy threads in a specific thread pool reaches a fixed threshold.
I can see the thread pool in the process metrics - for example "https-jsse-nio-8443" as shown here:
However, it seems it's not possible to create a custom alert for the above thread pool alone as only the total is available as metric "Tomcat busy threads":
Is there any way around that or is that a known limitation and potential candidate for an RFE?

The only workaround you can do is push information about thread pools state to dynatrace, and there are some options for that:
I think best option will be the first one.
