![]() ![]() This option is set by default for MariaDB, NGINX and PHP. – i.e.: it will attempt to heal a service. We called the tab on the server page “healing” because Monit will automatically restart degraded services. /etc/monit/conf-available – this folder holds configurations for individual items such as Nginx, MySQL etc./etc/monit/monitrc – this is the overall configuration file.There are some real-world examples of configurations for popular services on the M/Monit site as well.Īll Monit configuration files are located in the following locations: Learn more about Monit and how to configure it in the Monit Documentation. ![]() You can only customize what Monit is monitoring by directly editing its configuration files on the server. ![]() So, on a 2 processor system we will set the CPU alert level to 140% instead of 70%. We dynamically scale CPU thresholds based on the number of CPUs detected when Monit is installed. Note: CPU usage in Monit can exceed 100% – each processor is “100%” so on a dual processor system CPU usage can be 200%. If CPU usage is greater than 70% for 4 minutes (2 cycles) an alert will be sent.If memory used is greater than 85% for 6 minutes (3 cycles) an alert will be sent.If diskspace being used is greater than 80% an alert will be sent.If it uses greater than 85% of memory send an alert.If it uses greater than 70% of the CPU for 6 minutes (3 cycles) an alert will be sent.If it uses greater than 85% of memory for 6 minutes (3 cycles) it will be restarted.If it uses greater than 80% of the CPU for 10 minutes (5 cycles) it will be restarted.If it uses greater than 70% of the CPU for 4 minutes (2 cycles) an alert will be sent.I.e.: It will check the services every 2 minutes. We have set it up so that a “cycle” is 2 minutes. The thresholds are set dynamically based on the size of your server. When Monit is installed, we set it up with some simple default monitors. In particular, when you click on an individual item you will be able to see exactly what levels are being monitored and what actions will be triggered at those levels. You can click on an individual item in the first column to drill down into it. Your Monit dashboard should look something like this: To view the Monit dashboard all you need to do is click the LAUNCH MONIT button. Assuming that you’ve already pointed your DNS to the servers’ ip, you can just click the SSL Status button on the HEALING tab and an SSL certificate will be requested for you. Since the data you are transmitting can be sensitive we encourage you to activate SSL. And, if your email configuration is correct, you should receive your first couple of email alerts indicating that the Monit service is up and running. It shouldn’t take too long for the installation to complete – maybe a couple of minutes.Īfter installation is complete you will see a new set of options in that tab. After filling out the data in the three sections, click the INSTALL MONIT button.The third section is optional – if you have subscribed to the premium M/Monit service you can connect your server to it by entering your private URL to the services’ dashboard.The second section requires that you set up a connection to your EMAIL server so that alert emails can be sent.Otherwise MONIT will fail to start with a silent error.) ![]() ( The user name and password must consist of only ALPHANUMERICS. It also requires that you provide a user id and password to protect access to the Monit dashboard. Generally this is just a subdomain of a domain you already control.
