To configure Monit, you need to create a configuration file in the /etc/monit/conf.d/ directory:

sudo nano /etc/monit/conf.d/monitrc

Add the following lines to the configuration file:

set daemon 1800      # Check services every 1800 seconds (30 minutes)
set logfile syslog
set mailserver smtp.gmail.com port 587 username "your_email_address" password "your_email_password" using tlsv1
        # Change the email configuration as per your provider
set alert admin@example.com  # Add the email address you want to receive alerts on

Save and close the file by pressing CTRL + X, then Y, then Enter.

To check the configuration file syntax, use the following command:

sudo monit -t

If everything is okay, you should see the following output:

Control file syntax OK

Now you can start Monit:

sudo systemctl enable monit  # Enable Monit at boot
sudo systemctl start monit   # Start Monit

sudo nano /etc/monit/conf.d/monitrc

check process nginx with pidfile /run/nginx.pid
    start program = "/usr/sbin/nginx -c /etc/nginx/nginx.conf" with timeout 60 seconds
    stop program  = "/bin/systemctl stop nginx.service"

check process php-fpm with pidfile /run/php-fpm/php-fpm.pid
    start program = "/usr/sbin/php-fpm -D" with timeout 60 seconds
    stop program  = "/bin/systemctl stop php-fpm.service"

Save and close the file by pressing CTRL + X, then Y, then Enter.
