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 proc

Answer 1

The easiest way is using "htop". You can install "htop" (a fancier version of top) which will show you all your cores, process and memory usage.

Press "Shift+H" to show all process or press again to hide it. Press "F4" key to search your process name.

Installing on Ubuntu or Debian:

sudo apt-get install htop

Installing on Redhat or CentOS:

yum install htop
dnf install htop      [On Fedora 22+ releases]

If you want to compile "htop" from source code, you will find it here.
