Grafana can be self-hosted or accessed as a SaaS remedy by using the formal Grafana Cloud instance. In this post, you will study how to established up Grafana Cloud and configure it to display primary metrics from a Linux server. You will use the official Grafana Agent to acquire the data and send it to Grafana.

Obtaining Started out With Grafana Cloud

Begin by signing up for a absolutely free Grafana Cloud account. You can insert up to 10,000 info metrics utilizing the no cost prepare, as well as up to 50 GB each individual of stored logs and traces. Your facts will be retained for 14 times.

You can ensure that knowledge is flowing into your Grafana account by pressing the blue “Test integration” button back again in the world-wide-web UI. Soon after the take a look at completes, press the substitute “View dashboards” button to start out searching your server’s metrics.

Using the Dashboards

The Linux Server integration is also referred to as Node Exporter as it’s centered on the Prometheus collector of the exact title. It exports metrics from your compute nodes. Your dashboards will be grouped into a folder known as “Integration – Linux Node” by default. You can improve this identify by heading to the folder’s Configurations tab.

Two dashboards are provided with the integration. The “Node Exporter / Nodes” dashboard supplies an overview of system useful resource utilization. CPU usage, load typical, and memory use graphs are demonstrated prominently at the leading of the perspective. You will uncover graphs of disk use and network site visitors further down, adopted by the contents of your server’s system logs.

The USE Approach dashboard variant provides the facts from the point of view of the USE observability method. USE stands for Utilization, Saturation, and Faults:

  • Utilization is the share of time that a unique useful resource is consumed for, this kind of as latest CPU utilization.
  • Saturation is the volume of get the job done that resource performs, these as the modern load common.
  • Faults is the variety of mistake activities that manifest over a particular period of time.

The USE strategy dashboard delivers aspect-by-facet graphs of utilization and saturation for each and every components useful resource. Process logs are presented as panels at the bottom, enabling detection of documented glitches.

Dashboards instantly refresh though you are viewing them. You can modify the update interval employing the dropdown menu in the leading-right. It defaults to 30 seconds. This spot of the monitor also includes controls for altering the visible timeframe and switching involving display modes. Clicking the screen icon in the leading-right activates kiosk mode, suitable when you’re utilizing Grafana on a substantial display screen in a shared house.

Summary
