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]

Install Dependencies

sudo apt-get install libapache2-mod-php7.0 php7.0-cli php7.0-mysql php7.0-mysqli php7.0-gd php7.0-mcrypt php7.0-json php-pear snmp fping mysql-server mysql-client python-mysqldb rrdtool subversion whois mtr-tiny ipmitool graphviz imagemagick apache2

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.

Download and Extract Observium

sudo mkdir -p /opt/observium
cd /opt
sudo wget http://www.observium.org/observium-community-latest.tar.gz
sudo tar zxvf observium-community-latest.tar.gz

Configuration

create the MYSQL database and user

Enter your MySQL password that you gave the root user from before

mysql -u root -p

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.

GRANT ALL PRIVILEGES ON observium.* TO 'observium'@'localhost' IDENTIFIED BY 'dbpassword';
exit

Changing the config file

cd observium
sudo cp config.php.default config.php

Change the setting on the config.php to reflect your systems settings

sudo nano config.php

Set the username and password on the observium config file and an email address for alerts to get sent to.
