How can I monitor the thread count of a process on linux

Question

I would like to monitor the number of threads used by a specific process on Linux. Is there an easy way to get this information without impacting the performance of the process?

1. To add to the above comment. You can use this command to find the number of threads: find /proc/<PID>/task -maxdepth 1 -type d -print | wc -l . Just replace the <PID> with your process ID that you can get from top or using ps
2. @Navigatron: A simple ls /proc/<PID>/task | wc will do nicely.
