How to Install Adagios on Ubuntu Server Latest

Adagios is a web-based interface for Nagios monitoring solution. It provides an easy-to-use interface for managing alerts, hosts, and services, as well as generating in-depth reports.

Here's how you can install Adagios on Ubuntu Server latest:

Prerequisites

Before installing Adagios, make sure you have the following prerequisites:

• Ubuntu Server latest installed
• A non-root user with sudo privileges

Step 1: Install Required Packages

The first step is to install the required packages for Adagios:

sudo apt-get update
sudo apt-get install python-setuptools python-dev build-essential python-pip apache2 libapache2-mod-wsgi libapache2-mod-php php php-common php-cli php-mysql git-core nagios3

Step 2: Install Adagios

Once the required packages are installed, the next step is to install Adagios:

sudo pip install Adagios

Step 3: Configure Apache

Adagios uses Apache to serve the web interface, so the next step is to configure it. First, enable the necessary Apache modules:

sudo a2enmod rewrite wsgi php7.4

Next, create a new Apache Virtual Host file for Adagios:

sudo nano /etc/apache2/sites-available/adagios.conf

Add the following configuration to the file:

<VirtualHost *:80>
    ServerAdmin admin@example.com
    ServerName example.com
    DocumentRoot /var/www/adagios

    <Directory /var/www/adagios>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    WSGIDaemonProcess adagios user=www-data group=www-data threads=5
    WSGIScriptAlias / /var/www/adagios/wsgi.py

    Alias /media/ /usr/local/lib/python2.7/dist-packages/adagios/media/
    Alias /static/ /usr/local/lib/python2.7/dist-packages/adagios/static/

    <Directory "/usr/local/lib/python2.7/dist-packages/adagios/media">
        Require all granted
    </Directory>

    <Directory "/usr/local/lib/python2.7/dist-packages/adagios/static">
        Require all granted
    </Directory>
</VirtualHost>

Save and close the file.

Enable the Adagios site and restart Apache:

sudo a2ensite adagios.conf && sudo service apache2 restart

Step 4: Configure Nagios

Adagios uses Nagios as its monitoring engine, so you need to configure it to work with Adagios.

First, create a new Nagios configuration file for Adagios:

sudo nano /etc/nagios3/conf.d/adagios.cfg

Add the following configuration to the file:

define command{
        command_name    process-host-perfdata
        command_line    /usr/bin/python2.7 /usr/local/bin/process_performance_data.py host "$HOSTNAME$" "$HOSTSTATE$" "$OUTPUT$" "$LONGHOSTOUTPUT$" "$HOSTPERFDATA$"
        }

define command{
        command_name    process-service-perfdata
        command_line    /usr/bin/python2.7 /usr/local/bin/process_performance_data.py service "$HOSTNAME$" "$SERVICEDESC$" "$SERVICESTATE$" "$OUTPUT$" "$LONGSERVICEOUTPUT$" "$SERVICEPERFDATA$"
        }

define command{
        command_name    notify-host-by-adagios
        command_line    /usr/bin/printf "%b" "$NOTIFICATIONTYPE$\n$SERVICEDESC$\n$HOSTNAME$\n$HOSTOUTPUT$\n$LONGDATETIME$\n$CONTACTEMAIL$\n$NOTIFICATIONCOMMENT$\n$HOSTSTATE$\n$HOSTPERFDATA$" >> /usr/local/var/adagios/notification_send_pipe
        }

define command{
        command_name    notify-service-by-adagios
        command_line    /usr/bin/printf "%b" "$NOTIFICATIONTYPE$\n$SERVICEDESC$\n$HOSTNAME$\n$SERVICEOUTPUT$\n$LONGDATETIME$\n$CONTACTEMAIL$\n$NOTIFICATIONCOMMENT$\n$SERVICESTATE$\n$SERVICEPERFDATA$" >> /usr/local/var/adagios/notification_send_pipe
        }

Save and close the file.

Next, modify the Nagios configuration file to include the Adagios configuration file:

sudo nano /etc/nagios3/nagios.cfg

Add the following line to the file:

cfg_file=/etc/nagios3/conf.d/adagios.cfg

Save and close the file.

Restart Nagios to apply the changes:

sudo service nagios3 restart

Step 5: Access Adagios

Now that the installation and configuration are complete, you can access Adagios by pointing your web browser to the server's IP address or hostname.

You should see the Adagios login screen. Use the default username (admin) and password (adagios) to log in.

Conclusion

That's it! You've successfully installed Adagios on Ubuntu Server latest. Now you can use it to manage your Nagios monitoring system with ease.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
