I have recently learned about it and can’t help myself from sharing with my readers about this awesome piece of software. So I thought it would be fun to put a GUI Most people familiar with Linux have used the top command line utility to see what process is taking the most CPU or memory. Note that Linux has several timing mechanisms with various degrees of accuracy and precision; furthermore, if your system is very busy, your monitoring process might not get woken up until well after its timer has expired, and thus the wakeup might be delayed. Posted by: Vivek Gite The author is the creator of nixCraft and a seasoned sysadmin, DevOps engineer, and a trainer for the Linux operating system/Unix shell scripting.

What is supervisor? Supervisor is a client/server system that allows its users to control a number of processes on UNIX-like operating systems. You can get the memory usage of any process by using the proper _process_status string: simply replace os. server module, serving contents from the directory it was launched in. Monitoring the output of python subprocesses (self. There’s a similar utility called htop that is much easier to use for normal tasks. I start by describing the Serial I/O Kit, drive alert, water alarm, smoke detector and cameras that make up the hardware portion of the system. This process monitoring script can be used to monitor just one process, or multiple processes. A process marked <defunct> is partly dead, waiting to be fully destroyed by its parent. You will now need to edit files /etc/inittab and /boot/cmdline. This is very much useful when we want to see a command in continuously running phase similar to top command.
