How to install Graphite?

by ronnie•

Graphite is a powerful and flexible monitoring and graphing tool for time-series data. It is widely used in the industry to collect, store, and visualize metric data, enabling system administrators and developers to gain insights into the performance and health of their systems. As a supplier of Graphite, I understand the importance of a seamless installation process. In this blog post, I’ll guide you through the steps to install Graphite, ensuring you can set up this valuable tool effectively. Graphite

Prerequisites

Before you start installing Graphite, it’s essential to ensure that your system meets the necessary prerequisites. Graphite can be installed on various operating systems, including Linux distributions such as Ubuntu, CentOS, and Debian. For the purpose of this guide, I’ll assume you’re using Ubuntu 20.04, but the general principles can be applied to other systems with some modifications.

  1. Operating System: As mentioned, a Linux-based system like Ubuntu is recommended. However, Graphite can also run on other operating systems with appropriate configuration.
  2. Python: Graphite is written in Python, so you’ll need Python installed on your system. For Ubuntu 20.04, Python 3.8 is installed by default, which is compatible with Graphite.
  3. Web Server: You’ll need a web server to serve the Graphite web interface. Popular web servers for this purpose include Apache and Nginx. In this guide, we’ll use Apache.
  4. Database: Graphite uses a database to store metric data. The most common choice is Whisper, which is a simple, fixed-size database format optimized for time-series data.

Step 1: Update Your System

First, log in to your server as a user with sudo privileges. Then, update the package list and upgrade the installed packages to their latest versions:

sudo apt update
sudo apt upgrade -y

This ensures that your system has the latest security patches and software updates, which is crucial for a stable installation.

Step 2: Install Required Packages

Graphite depends on several system packages, including Python libraries and web server components. Install the necessary packages using the following command:

sudo apt install -y python3 python3-pip python3-dev libcairo2-dev libffi-dev build-essential apache2 libapache2-mod-wsgi-py3
  • python3: The Python interpreter.
  • python3-pip: The Python package manager, which we’ll use to install Graphite and its dependencies.
  • python3-dev: Python development headers, required for building some Python packages.
  • libcairo2-dev and libffi-dev: Libraries required for rendering graphs.
  • build-essential: Tools for compiling software, such as gcc and make.
  • apache2: The web server that will serve the Graphite web interface.
  • libapache2-mod-wsgi-py3: The Apache module that allows running Python web applications.

Step 3: Install Graphite

Now that you have the necessary system packages installed, you can install Graphite using pip. It’s a good practice to create a virtual environment first to isolate the Graphite installation from other Python projects on your system.

sudo pip3 install virtualenv
mkdir ~/graphite_env
cd ~/graphite_env
virtualenv -p python3 .
source bin/activate
pip install carbon whisper graphite-web
  • virtualenv -p python3 .: Creates a new virtual environment named . (the current directory) using Python 3.
  • source bin/activate: Activates the virtual environment.
  • pip install carbon whisper graphite-web: Installs Carbon, Whisper, and Graphite Web, the three main components of Graphite.

Step 4: Configure Carbon

Carbon is the daemon responsible for receiving and storing metric data. You need to configure it to start collecting data.

cd /opt/graphite/conf
sudo cp carbon.conf.example carbon.conf
sudo cp storage-schemas.conf.example storage-schemas.conf

Edit the storage-schemas.conf file to define how long different types of metrics should be stored. For example, you might want to store high-resolution data for a short period and lower-resolution data for a longer period. Here’s a basic example:

[default]
pattern = .*
retentions = 60s:1d, 300s:7d, 3600s:30d

This configuration stores data at a 60-second resolution for 1 day, a 300-second resolution for 7 days, and a 3600-second resolution for 30 days.

Step 5: Configure Graphite Web

Graphite Web provides the web interface for querying and visualizing metric data. You need to configure it to work with your web server (Apache in this case).

cd /opt/graphite/webapp/graphite
sudo cp local_settings.py.example local_settings.py

Edit the local_settings.py file to modify settings such as the database connection and the secret key. Here are some important settings to configure:

SECRET_KEY = 'your_secret_key'
TIME_ZONE = 'Your/Timezone'
DATABASES = {
    'default': {
        'NAME': '/opt/graphite/storage/graphite.db',
        'ENGINE': 'django.db.backends.sqlite3',
    }
}

Generate the database schema and create a superuser:

python manage.py migrate
python manage.py createsuperuser

Step 6: Configure Apache

Configure Apache to serve the Graphite web interface. Create a new Apache configuration file:

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

Add the following content to the file:

<VirtualHost *:80>
    ServerName graphite.example.com
    DocumentRoot /opt/graphite/webapp/graphite
    ErrorLog ${APACHE_LOG_DIR}/graphite_error.log
    CustomLog ${APACHE_LOG_DIR}/graphite_access.log combined

    WSGIDaemonProcess graphite processes=5 threads=5 display-name=%{GROUP}
    WSGIProcessGroup graphite
    WSGIScriptAlias / /opt/graphite/webapp/graphite/wsgi.py

    <Directory /opt/graphite/webapp/graphite>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>
</VirtualHost>

Enable the new site and restart Apache:

sudo a2ensite graphite.conf
sudo systemctl restart apache2

Step 7: Start Carbon

Finally, start the Carbon daemon to begin collecting metric data:

sudo /opt/graphite/bin/carbon-cache.py start

You can verify that Carbon is running by checking the log files in /opt/graphite/storage/log/carbon-cache/.

Post-Installation Checks

After installing and configuring Graphite, it’s important to perform some post-installation checks to ensure everything is working correctly.

  1. Web Interface: Open your web browser and navigate to http://your_server_ip, where your_server_ip is the IP address of your server. You should see the Graphite web interface. Log in using the superuser credentials you created earlier.
  2. Metric Collection: You can start sending test metrics to Carbon to verify that it’s receiving and storing data correctly. There are various tools available for sending metrics, such as netcat. Here’s an example of sending a test metric:
echo "test.metric 1 `date +%s`" | nc localhost 2003

Refresh the Graphite web interface and check if the metric is being displayed.

Troubleshooting

If you encounter any issues during the installation or operation of Graphite, here are some common troubleshooting steps:

  1. Check Log Files: The log files in /var/log/apache2 and /opt/graphite/storage/log/carbon-cache/ can provide valuable information about what’s going wrong. Look for error messages and warnings.
  2. Permissions: Make sure that the user running the Apache and Carbon processes has the necessary permissions to access the Graphite files and directories.
  3. Firewall: Check if your firewall is blocking the necessary ports. Carbon uses port 2003 by default for receiving metrics, and Apache uses port 80 for serving the web interface.
