There are three options on how to select which process(es) to check. The script can be found at: Ī detailed description of what the script can do and how it works is as below: It also reads and interprets the files under /proc/ to provide more information. It uses established tools like cat, and ps partly for historical reasons, but also for simplified security. Today's script is (I hope) a step in the right direction. Hopefully others will continue to build on this work and extend it further. I have been striving to provide a better alternative both for Nagios based monitoring solutions (and AWS cloudwatch, but that will be a later post). Strangely I have found that the basic monitoring of Unix processes has been largely ignored, with the checks available lacking basic features. I have had the privilege to work with some amazing people and benefited from their work. Over the past few years I have had the opportunity to work with several monitoring systems and many checks (both scripts and executables).
