1. composer install
2. Add config/servers.ini (you can use servers.template.ini)
3. Set up a crontab job to run cron every minute:

   * * * * * cd /path/to/monit-graph && php src/scripts/cron.php >> /var/log/monit-graph.log

To setup Monit on Ubuntu, please follow the below steps.

Install Monit

sudo apt-get update
sudo apt-get install monit

Edit configuration file for Monit

sudo vi /etc/monit/monitrc

Make sure the following parameters are set correctly (these are examples, adjust accordingly):

set idfile /var/run/monit-id
set statefile /var/run/monit-state
set daemon 60
set logfile /var/log/monit.log

set mailserver localhost
set mail-format { from: monit@mydomain.com }

set alert myemail@myemaildomain.com	                 # receive all alerts
set httpd port 2812 and use the address XX.XX.XX.XX  # Remove "and use the address XX.XX.XX.XX", if not bind to specific IP
  ssl enable                                         # Enabling SSL
  pemfile /etc/ssl/monit.pem                         # The PEM file
  signature disable                                  # No server signature to send
  allow mylogin:"mypassword"                         # Login

Remember to allow httpd to run, or else Monit graph cannot contact you.

Add services to Monit

Add a few configuration files into the /etc/monit/conf.d/ directory. You can use the examples from the monitrc directory.

Check if the configuration are good:

monit -t

Restart Monit with the new configuration

Restart

service monit restart

Tips

1. If the script have trouble managing big amounts of data, try increase the allowed allocated memory in a .htaccess

2. REMEMBER to password protect the directory with .htaccess or anything appropriate

3. Loading many services can be very heavy for your browser, try specify the services you wish be shown.
