Perhaps I'm missing something, but all this (and much more) can be obtained with several binaries provided by the JDK itself:

1. jcmd -l (or jps)
   Lists all local java processes that you can control with the rest of the commands
2. jcmd <pid> help
   Lists all commands accepted by the target java process
3. jinfo -sysprops <pid>
   Lists system properties for that process (-flags also available)
4. jstack <pid>
   Fetches the thread stack traces for the process
5. jcmd <pid> JFR.start ...
   Example of one of the commands to apply to a process (start recording info for performance tuning)

The list goes on and on.
