How to Install Graphite on Fedora CoreOS Latest?

Graphite is an enterprise-level real-time graphing system that allows you to store, retrieve, and visualize numeric time-series data. In this tutorial, we will show you how to install Graphite on Fedora CoreOS latest version.

Prerequisites

Before we start, please make sure that you have the following prerequisites:

• A running instance of Fedora CoreOS latest version.
• Basic knowledge of Linux commands.

Step 1: Install Python and Pip

Graphite is written in Python, so we need to install Python and Pip first. To install Python, run the following command:

sudo dnf install -y python3

To install Pip, run the following command:

sudo dnf install -y python3-pip

Step 2: Install Carbon

Carbon is the component of Graphite that is responsible for receiving metrics from the network and writing them to disk. To install Carbon, run the following command:

sudo pip3 install carbon

Step 3: Install Whisper

Whisper is the component of Graphite that is responsible for storing the time-series data on disk. To install Whisper, run the following command:

sudo pip3 install whisper

Step 4: Install Graphite web application

Graphite web application provides a web interface for visualizing the time-series data that is stored in Whisper. To install Graphite web application, run the following command:

sudo pip3 install graphite-web

Step 5: Configure Graphite

Once Graphite is installed, we need to configure it. To do this, copy the default configuration file to local_settings.py:

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

Edit local_settings.py to set the secret key and database credentials. For example:

SECRET_KEY = 'my-secret-key'
DATABASES = {
    'default': {
        'NAME': 'graphite',
        'ENGINE': 'django.db.backends.postgresql',
        'USER': 'graphiteuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': ''
    }
}

Step 6: Configure Carbon

Next, we need to configure Carbon. The default configuration file is located at /opt/graphite/conf/carbon.conf. You can edit this file to set the storage schema and retention policy. For example:

[default]
pattern = .*
retentions = 60s:1d

[my_custom_metrics]
pattern = my_custom_metrics.*
retentions = 30s:5m,1m:10m,5m:1d

Step 7: Start Carbon and Graphite web application

After configuring Graphite and Carbon, we need to start them. To start Carbon, run the following command:

sudo systemctl start carbon.service

To start Graphite web application, run the following command:

sudo systemctl start apache.service

Step 8: Access Graphite web application

Once Carbon and Graphite web application are running, you can access the Graphite web interface by visiting http://localhost/. You should see a login screen, where you can enter your username and password.

Congratulations, you have successfully installed Graphite on Fedora CoreOS latest version. Now you can start collecting and visualizing your time-series data using Graphite.
