The steps should be similar for other Linux systems and Ubuntu versions. It provides all the steps required to configure Monit on Ubuntu 20.04 LTS. This tutorial provides the steps required to configure Monit on the popular Linux distribution Ubuntu. In this tutorial, we will discuss configuring Monit for MySQL, Apache, and NGINX. We have also discussed configuring Monit to trigger alert emails. And after you’re done modifying the config files, you’ll need to reload Monit again.In the previous tutorial, we have discussed installing Monit and how to update the default configuration. Note that all paths must be fully qualified, including /bin/bash and paths to executables in your local bin. If 1 restart within 1 cycle then exec "/bin/bash -c 'PROCESS=Nginx /usr/local/bin/slack-webhook.sh'" If changed pid then exec "/bin/bash -c 'PROCESS=Nginx /usr/local/bin/slack-webhook.sh'" For example, you could set up a script to send you Slack notifications, store it as /usr/local/bin/slack-webhook.sh, and run it whenever nginx changes PID or is restarted by Monit: check process nginx with pidfile /var/run/nginx.pid Obviously, you’ll also need to set the email address it sends to: set alert since Monit has the ability to run scripts with the exec command, you can set up custom alerts however you’d like. The second line tells Monit to queue alerts, if the mail server isn’t reachable for whatever reason.

If totalmem > 600 MB for 5 cycles then restart It should automatically restart if the process goes down, with no additional config, but if you want to restart based on resource usage, you’ll have to specify that yourself with a few if statements: check process nginx with pidfile /var/run/nginx.pid You’ll need to pass Monit a command to start and stop your process. check process nginx with pidfile /var/run/nginx.pid Usually, this is done with the processes PID file (often found in /var/run/) which stores the current PID of the running instance of that process, since the PID will change whenever the process restarts. Monit can then be configured to monitor individual processes.
