Monitoring a Linux host using the Linux host integration

This guide will show you how to install the Linux node integration and then deploy the Grafana Agent to a Linux node and use it to push metrics to Grafana Cloud and use the preconfigured dashboard to visualize those metrics.

Prerequisites

  • A Grafana Cloud account, as shown in Quickstarts
  • A Linux machine
  • Command line (terminal) access to that Linux machine

Note: The installation process for integrations is changing rapidly. What you see may differ slightly from what is shown here.

Install the integration and agent

  1. Login to Grafana.com to enter the Cloud Portal.

  2. Click Log In in the Grafana box. The first time you log in to Grafana from the Cloud Portal you are automatically taken to the Walkthrough. If this is not your first time, follow the next two steps, otherwise you can skip ahead. Cloud Portal

  3. Click the Onboarding logo (it looks like a lightning bolt) in the left column. Grafana Home page

  6. To install and configure the Grafana Agent on your Linux machine, follow the instructions you are provided. When you are done installing the agent and it is running, click Check Connection to confirm the agent is sending metrics that Grafana Cloud is receiving. Integration installation

  7. If metrics are being received, you will receive a notification. Click See the dashboard. Successful Integration notification

  8. Click Close wizard to view the Manage Dashboards page where you find a list of all of the preconfigured dashboards. The Linux server dashboard is called Nodes and is found in the Linux Node folder. Click it to open the dashboard. Integration success

Conclusion

Using this guide, you have installed the Linux integration into Grafana, which installed a preconfigured dashboard for metrics visualization. During the process, you installed the Grafana Agent on your Linux machine and configured the agent to send metrics to Grafana Cloud to make use of that integration.

This is the result.
