Tomcat – Howto find Tomcat current thread count

On my Linux server I run tomcat as root and when I run ps aux it gives the following output.

root     25667  0.1 29.2 4574004 306980 ?      Sl   Apr27  33:57 /usr/local/java/bin/java -Djava.util.logging.config.file...

Thre is only parent process, but when I run htop I can see all other child process (which are threads?). Sample output for a few lines given below.

  PID USER      PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command

So I want to get child process list with a single command. I set maxThreads to 200 in config file, and want to check current thread count by counting child threads.
