Guides - Deploying Prometheus through the Linode Marketplace
Quickly deploy a Compute Instance with many various software applications pre-installed and ready to use.
Use Prometheus to collect metrics and receive alerts with this open-source monitoring tool. Prometheus monitors targets that you define at given intervals by scraping their metrics HTTP endpoints. This tool is particularly well-suited for numeric time series data, which makes it ideal for machine-centric monitoring as well as monitoring of highly dynamic service-oriented architectures.
Deploying a Marketplace App
The Linode Marketplace allows you to easily deploy software on a Compute Instance using the Cloud Manager. See Get Started with Marketplace Apps for complete steps.
Log in to the Cloud Manager and select the Marketplace link from the left navigation menu. This displays the Linode Create page with the Marketplace tab pre-selected.
Under the Select App section, select the app you would like to deploy.
Complete the form by following the steps and advice within the Creating a Compute Instance guide. Depending on the Marketplace App you selected, there may be additional configuration options available. See the Configuration Options section below for compatible distributions, recommended plans, and any additional configuration options available for this Marketplace App.
Click the Create Linode button. Once the Compute Instance has been provisioned and has fully powered on, wait for the software installation to complete. If the instance is powered off or restarted before this time, the software installation will likely fail.
To verify that the app has been fully installed, see Get Started with Marketplace Apps > Verify Installation . Once installed, follow the instructions within the Getting Started After Deployment section to access the application and start using it.
NoteEstimated deployment time: Prometheus should be fully installed within 2-5 minutes after the Compute Instance has finished provisioning.
- Supported distributions: Debian 9, Debian 10
- Recommended minimum plan: 4GB Dedicated CPU or Shared Compute Instance
Getting Started after Deployment
Access Your Prometheus Instance
Now that your Prometheus Marketplace App is deployed, you can log into Prometheus to access its expression browser , alerts, status, and more.
Open a browser and navigate to
192.0.2.0with your Linode’s IP address . This will bring you to your Prometheus instance’s expression browser.
Verify that Prometheus is serving metrics by navigating to
192.0.2.0with your Linode’s IP address . You should see a page of metrics similar to the example below.
Grafana , the open source analytics and metric visualization tool, supports querying Prometheus. Consider deploying a Grafana instance with Marketplace Apps to create visualizations for your Prometheus metrics .
Prometheus Default Settings
- Prometheus' main configuration is located in the
- This file includes a scrape configuration for Prometheus itself.
and evaluation interval are configured globally to be
scrape_intervalparameter defines the time between each Prometheus scrape, while the
evaluation_intervalparameter is the time between each evaluation of Prometheus' alerting rules .
Prometheus Node Exporter
is added and enabled. This
third-party system exporter
is used to collect hardware and OS metrics. Your Node Exporter metrics are sent to port
9100of your Linode.
NoteCurrently, Linode does not manage software and systems updates for Marketplace Apps. It is up to the user to perform routine maintenance on software deployed in this fashion.
