Today we will be installing Observium
Observium is a Network Management and Monitoring System that collects data from multiple devices using SNMP and allows you to monitor all of the networks devices via an easy to use interface. It is PHP-based and uses a MySQL database to store data.
Note
This guide works with Ubuntu 16.04
Install
Connect to your server via SSH
ssh [email protected]

Enter the Mysql password for the root user. Note: For security make this one different than your server’s password, and try not to use this user in any application that requires a database to store and pull data from.

Once in MySQL enter the following commands to create the database, the user and to allow the user access to the database.
CREATE DATABASE observium DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Make sure to change the Observium database password with your own, you will need this in the next step.

exit
Changing the config file
cd observium
sudo cp config.php.default config.php
