Graphite is a free and open source tool that can be used to track and graph the performance of computer systems. Graphite is an application that can be used to gather information from your system and display it through its web interface.

In this tutorial, I will explain how to install and configure Graphite on Ubuntu 16.04.

Prerequisites

  • A newly deployed Vultr Ubuntu 16.04 server instance.

  • A non-root user with sudo privileges setup on your server.

  • A static IP address 192.168.0.227 configured on your system.

Step 1: Update the system

First, update your system to the latest stable version by running the following command:

sudo apt-get update -y

sudo apt-get upgrade -y

Once your system is updated, restart your system to apply these changes:

sudo reboot

Step 2: Install Graphite

Graphite is made up of several components including, the graphite web application, carbon storage backend, and the database library, whisper. Each of these components are available in Ubuntu default repository. You can install these by just running the following command:

sudo apt-get install graphite-web graphite-carbon -y

Once the installation is complete, you can proceed to the next step.

Step 3: Install and configure PostgreSQL

The Graphite web application is a Django Python application that needs PostgreSQL to store its data. You can install PostgreSQL and the helper packages by running the following command:

sudo apt-get install postgresql libpq-dev python-psycopg2 -y

After installing PostgreSQL, you will need to create a PostgreSQL user and database for Graphite to use.

First, login to PostgreSQL shell with the following command:

sudo -u postgres psql

Next, create a graphite user and secure it with a password:

postgres=# CREATE USER graphite WITH PASSWORD 'password';

Next, create a graphite database and give ownership to the graphite user:

postgres=# CREATE DATABASE graphite WITH OWNER graphite;

Finally, exit from the PostgreSQL shell:

postgres=# \q

Step 4: Configure Graphite

Once the database is setup properly, you will need to configure the Graphite web application. You can do this by editing the local_settings.py file:

sudo nano /etc/graphite/local_settings.py

Edit the file as shown below:

SECRET_KEY = 'your-secret-key'

TIME_ZONE = 'America/Los_Angeles'

USE_REMOTE_USER_AUTHENTICATION = True

DATABASES = {

    'default': {

        'NAME': 'graphite',

        'ENGINE': 'django.db.backends.postgresql_psycopg2',

        'USER': 'graphite',

        'PASSWORD': 'password',

        'HOST': '127.0.0.1',

        'PORT': ''

    }

}

Save and close the file, when you are finished.

Next, run the following command to sync the database to create the correct structure:

sudo graphite-manage migrate auth

sudo graphite-manage syncdb

You will be asked to create a superuser account for the database as shown in the following output:

You have installed Django's auth system, and don't have any superusers defined.

Would you like to create one now? (yes/no): yes

Username (leave blank to use 'root'): 

Email address: you@example.com

Password:

Password (again):

Superuser created successfully.

Step 5: Configure Carbon

Now, you will need to configure Carbon, the Graphite storage backend by editing the service configuration file, graphite-carbon.

sudo nano /etc/default/graphite-carbon

Change the file to enable carbon-cache to start on boot:

 CARBON_CACHE_ENABLED=true

Save and close the file, when you are finished.

Next, open the Carbon configuration file:

sudo nano /etc/carbon/carbon.conf

Change the file as shown below to enable log rotation:

ENABLE_LOGROTATION = True

Save the file, then configure storage schemas. To do so, edit the storage schema file to tell Carbon how long to store values and how detailed these values should be there:

sudo nano /etc/carbon/storage-schemas.conf

Add the following section at the end of the file:

[test]

pattern = ^test\.

retentions = 6s:4h,1m:1d

Save and close the file when you are finished.

Next, you will need to define the way you want aggregation to occur in a file called storage-aggregation.conf. Copy the example configuration file to the Carbon configuration directory:

sudo cp /usr/share/doc/graphite-carbon/examples/storage-aggregation.conf.example /etc/carbon/storage-aggregation.conf

Finally, start Carbon service with the following command:

sudo systemctl start carbon-cache

Step 6: Configure Apache for Graphite

You will also need to install the Apache web server to use the Graphite web interface. You can install Apache with the following command:

sudo apt-get install apache2 libapache2-mod-wsgi -y

Next, copy the graphite example configuration file to Apache with the following command:

sudo cp /usr/share/graphite-web/apache2-graphite.conf /etc/apache2/sites-available/

Once the installation is complete, disable the default virtual host file and enable the graphite virtual host file with the following command:

sudo a2dissite 000-default

sudo a2ensite apache2-graphite

Finally, restart the Apache service to apply these changes:

sudo systemctl restart apache2

Step 7: Access Graphite web interface

Next, You will need to allow port 80 through UFW firewall to access the Graphite web interface. You can do this by running the following commands:

sudo ufw allow 80

It's time to access Graphite web interface. Open your favorite web browser and type the URL http://192.168.0.227. Then, provide your login credentials (your root username and password), you will see the Graphite login screen.
