Where are the Monit configuration files located in the Hestia control panel? The answer is simple:

path:

• /etc/monit

In this path, you can find all the configuration files about Monit. If you want Monit to run properly and monitor various services on your server, you have to make some changes in this directory.

Key configuration files:monitrc

All configurations are actually collected in one file, that is:

file:

• /etc/monit/monitrc

This file is the "brain" of Monit. Here you can define which services need to be monitored, how to monitor them, and what actions to take when problems occur. Does it sound important? It is! If you rely on Nginx, PHP-FPM,MySQLThis is where you need to pay special attention.

Default configuration: Hestia's thoughtful settings

Fortunately, HestiaCP does a lot of work for us. By default, Hestia has configured Monit for you to monitor the following key services:

• ：As one of the most popular web servers, the importance of Nginx needs no further explanation.
• php-fpm: A critical service for handling PHP requests, especially on dynamic websites.
• MySQL：The core of database service, almost all dynamic websites cannot do without it.
• Fail2ban: An essential tool for security protection that helps you resist brute force attacks.
• Postfix: Services that handle mail.
• Dovecot: Guardian of IMAP and POP3 mail services.

These default configurations already cover most of the core services of the server, but you may have some specific requirements, then you will need to make some customized configurations.

Custom Monit configuration: build your own monitoring system

Although the default configuration is already very powerful, there are always scenarios where you need to monitor other services or processes, such as Redis, MongoDB, etc. To customize Monit's configuration, you only need to edit/etc/monit/monitrcfile.

Here you can add new monitoring rules, such as:

check process redis-server with pidfile /var/run/redis/redis-server.pid
    start program = "/etc/init.d/redis-server start"
    stop program  = "/etc/init.d/redis-server stop"
    if failed port 6379 then restart
    if 5 restarts within 5 cycles then timeout

In this way, you can let Monit protect your Redis service and ensure that if it hangs, Monit can automatically restart it.

Don't forget to restart Monit

After you have made changes to the configuration file, there is a very important step:Restart MonitIf you do not restart, Monit will not load your latest configuration. Therefore, every time you modify the configuration, you must execute the following command:

systemctl restart monit

This step cannot be forgotten, otherwise all modifications will be in vain.

Visit the Monit dashboard: a powerful tool for real-time monitoring

Now that Monit is configured, you must be wondering what it is doing, right? Monit comes with a dashboard that allows you to view the status of all monitored services in real time. All you need to do is visit:

http://your_server_ip:2812

By default, Monit's dashboard is not password protected. So, remember to set a strong password or restrict access to specific IP addresses to ensure security.

Conclusion: Take control of your server, start with configuring Monit

By configuring Monit correctly, you can greatly improve the reliability of your server. After all, no one wants to be woken up by a phone call in the middle of the night telling you that your website is down, right? With Monit, you can prevent many problems in advance and automatically handle them when they occur, making your server truly "self-healing."

So, don't hesitate any longer, check your Monit configuration! If you haven't configured it yet, or just used the default configuration, now is the best time to start customizing your server monitoring system.
