In some documentation about generating thread dumps, there's an optional step to install the Thready plugin to make Tomcat threads more informative which helps in troubleshooting.

Since ATST (Atlassian Troubleshooting and Support Tools) version 1.32.1, the feature called thread diagnostics is built in to fulfill the same purpose. The documentation about thread diagnostics can be found in Support Tools Plugin - Thread diagnostics.

This request is to identify and to update documentation which has the suggestion to use Thready to be replaced with the guide to use the thread diagnostics feature. Generating a thread dump - Linux/Unix Alternative: Generating thread dumps using scripts is one of the documentation to be updated.
