Grafana is an open up-resource observability system for generating dashboards that visualize datasets. You can use it to conveniently monitor server data such as CPU consumption, community throughput, and uptime.
Grafana can be self-hosted or accessed as a SaaS solution by using the official Grafana Cloud occasion. In this report, you’ll learn how to established up Grafana Cloud and configure it to demonstrate primary metrics from a Linux server. You will use the formal Grafana Agent to gather the information and send it to Grafana.
Receiving Started out With Grafana Cloud
Start out by signing up for a cost-free Grafana Cloud account. You can increase up to 10,000 knowledge metrics working with the cost-free program, as properly as up to 50 GB every of stored logs and traces. Your info will be retained for 14 times.
Abide by the indication up technique till you arrive at the welcome monitor. You can accessibility it by clicking the Grafana icon in the best-remaining of the aspect menu if you end up in a various spot.
Introducing Your Server as a Data Supply
When you are on the welcome display screen, click the blue “Connect data” button to get started location up your dashboard. You’ll arrive on the Integrations and Connections webpage. These deliver pre-created dashboard layouts with officially supported connectors for prevalent information sources. They are the fastest way to get Grafana up and running.
Either scroll down or use the searchbar to uncover the “Linux Server” integration. Click its tile to watch the information and facts website page. This delivers a description of the integration and its usage instructions.
Alter the running method and method architecture parameters in the “Choose your OS” segment to match the equipment you will be monitoring.
Future scroll down the webpage and press the blue “Install integration” button to incorporate the dashboards to your account.
Installing Grafana Agent on Your Server
The website page will update to display screen a Grafana Agent installation script. The script downloads the accurate Agent binary for the system you selected and quickly configures authentication with your Grafana Cloud API vital.
Open a terminal to your server and run the shown script.
$ sudo ARCH=amd64 GCLOUD_STACK_ID="XXXXX" GCLOUD_API_Essential="XXXXXX" GCLOUD_API_URL="https://integrations-api-eu-west.grafana.internet" /bin/sh -c "$(curl -fsSL https://raw.githubusercontent.com/grafana/agent/launch/generation/grafanacloud-install.sh)"

Grafana Agent is now functioning! To examine the position of your Agent, operate:
sudo systemctl position grafana-agent.service
Grafana Agent is a small version of the Prometheus information collector. It runs as a provider that periodically scrapes metrics and logs from your machine. Set up is effective if you see the Grafana Agent is now working concept at the stop of the script’s output.
You can affirm that data is flowing into your Grafana account by pressing the blue “Test integration” button back again in the website UI. After the check completes, push the alternative “View dashboards” button to begin searching your server’s metrics.
Employing the Dashboards
The Linux Server integration is also referred to as Node Exporter as it’s based on the Prometheus collector of the exact name. It exports metrics from your compute nodes. Your dashboards will be grouped into a folder named “Integration – Linux Node” by default. You can improve this identify by heading to the folder’s Options tab.
Two dashboards are bundled with the integration. The “Node Exporter / Nodes” dashboard delivers an overview of method useful resource utilization. CPU use, load regular, and memory consumption graphs are demonstrated prominently at the prime of the look at. You are going to come across graphs of disk utilization and network visitors further more down, followed by the contents of your server’s method logs.
The USE System dashboard variant offers the knowledge from the standpoint of the USE observability technique. USE stands for Utilization, Saturation, and Glitches:
- Utilization is the share of time that a specific resource is consumed for, these kinds of as latest CPU usage.
- Saturation is the volume of operate that source performs, this kind of as the new load average.
- Problems is the quantity of error activities that come about above a certain interval.
The USE technique dashboard provides facet-by-facet graphs of utilization and saturation for each and every hardware resource. Process logs are provided as panels at the base, allowing for detection of described glitches.
Dashboards immediately refresh whilst you are viewing them. You can adjust the update interval employing the dropdown menu in the best-proper. It defaults to 30 seconds. This region of the display screen also has controls for changing the noticeable timeframe and switching between display modes. Clicking the display screen icon in the leading-correct activates kiosk mode, perfect when you’re employing Grafana on a huge show in a shared house.
Summary
Grafana Cloud can make it uncomplicated to established up advanced server checking dashboards making use of Grafana Agent with the Linux Server integration. It presents pre-designed dashboards so you really do not require to manually manipulate metrics or set up graphical panels.
The integration is a setting up position which is ready to be personalized to match your observability desires. You can modify the dashboards by adding new metrics and switching how current types are shown. Click on the settings cog icon in the top-correct of the dashboard, then push the “Make editable” button to help the editing controls. This will enable you add new panels to your dashboards and transform their variables and screen choices in the configurations.
