How to Install Observium on Void Linux

Observium is a network monitoring tool that provides comprehensive and detailed analysis of network traffic, devices and systems. It can monitor everything from servers and switches, to routers and firewalls. If you are using Void Linux and would like to install Observium on your system, follow these simple steps:

Prerequisites

Before installing Observium, you need to ensure that your system meets the following requirements:

  • Root user access
  • Web server software (e.g., Apache, nginx)
  • PHP version 5.4.0 or later
  • SNMP enabled on the devices being monitored
  • A supported database (e.g., MySQL, MariaDB, PostgreSQL)

Step 1: Install Required Packages

The first step is to install the required packages for Observium. Use the following command to install Apache, PHP and MySQL/MariaDB:

# xbps-install -S apache php mariadb

Step 2: Download and Install Observium

Next, download and install Observium by using the following commands:

# cd /opt
# git clone https://github.com/observium/observium.git
# cd observium
# cp config.php.default config.php

Step 3: Configure Observium

After copying the default configuration file, edit it using your preferred text editor (e.g., nano, vim) to set the database configuration and SNMP parameters:

# nano config.php

Change the following lines to match your database and SNMP credentials and preferences:

$config['db_host'] = 'localhost';
$config['db_user'] = 'observium';
$config['db_pass'] = 'password_here';
$config['db_name'] = 'observium';
$config['snmp']['community'] = array("public");

Save and exit the file.

Step 4: Initialize the Database

Run the following command to initialize the Observium database:

# ./discovery.php -u

Step 5: Run Observium

Start observing by running the following command:

# ./observium_poller.php -h all

You should now be able to access Observium at http://localhost/ or your server's IP address. Use the default login credentials (username: admin, password: admin) to log in and start monitoring your network.

Congratulations! You have successfully installed Observium on Void Linux. Happy monitoring!
