I'm not sure why zero threads would be shown, but perhaps one of the Tomcat lists would be of better help in debugging the Tomcat manager webapp? If you just want to inspect what threads are running, there are generic Java debugging tools that would let you obtain overall JVM thread dumps. Is there something you're trying to solve by doing this?
---I am just trying to arrive at the optimum value of "MaxThreads" for Tomcat. 200 is the default value in Tomcat and I want to monitor them to see if I need more than 200 threads when the concurrency increases. The fact that the connection uses RemoteApp (or RDP, or VNC, or SSH, etc.) is opaque to the client and webapp. Everything is just the Guacamole protocol at that level. What do you mean by "do the Java Threads get busy"? ---What i meant was that when the user is interacting within a RemoteApp (like any legacy applications) i.e. clicking buttons, selecting dropdown values, typing some text etc. does it use Tomcat threads? My understanding is it should, but just wanted to confirm.
