Monit - Processes and Applications Monitoring

Monit is a free open source utility for managing and monitoring, processes, programs, files, directories and filesystems on a UNIX system. Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations.

Note: AstLinux 1.2.2 or later is required

The AstLinux Web Interface is used for configuration, click on Configure Monit

Network tab → Network Services:

Enable by clicking on “Configure Monit” and enable “Monitoring”, additionally you will have a few options:

Tip -> If your Monit config includes a “check network” for a 1 GB interface, it is suggested to set the “Check Interval” to 30 seconds.

The “To” address entry may include multiple space separated email addresses.

Much of the configuration is autogenerated. You just need to enable Monitoring and enter the Monit notification email address.

Once Monit has been enabled and restarted, the Monit services may be customized by using the Edit tab…

Or use the CLI and edit the file: /mnt/kd/monit/monit.d/services.conf

Apply changes by restarting Monit.

Tip -> From the CLI, a handy command to check the syntax of your monitrc file and all included monit.d/*.conf files…

monit -t

should respond with something like: Control file syntax OK

If you need a more specialized configuration, copy /etc/monit/monitrc to /mnt/kd/monit/monitrc, edit it and restart Monit.

By default the Monit tab is not shown, enable it via the Prefs tab…

The “Monit Service Manager” may be explored by using the Monit tab:
