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.
Before we start, please make sure that you have the following prerequisites:
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
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
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
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
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': ''
}
}
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
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
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.
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!
Alternatively, for the best virtual desktop, try Shells!
