ThreadNamingPipelineServlet modifies a request’s thread name by appending session- and user-specific information. This servlet can be useful in troubleshooting hanging threads for a given site, as the appended data can help identify the source of the problem—for example, hanging threads that all share the same remote user IP address.
As installed, the servlet class appends the following data to the original thread name:
Request URI
Session ID
Remote user IP address
User profile ID
For example, given the following JBoss HTTP handler thread name:
http-0.0.0.0-8180-2
ThreadNamingPipelineServlet might modify the thread name as follows:
http-0.0.0.0-8180-2 requestURI=/PioneerCycling/example.jsp jsessionid=4CDA4BC58E0F38F52AA7F87E06446888.drp1 remoteAddr=127.0.0.1 userid=1240001
