Day 76 Build a Grafana dashboard

Grafana Dashboard

• A Grafana dashboard offers a comprehensive view of your data, allowing you to track metrics and trends through different visualizations. Dashboards are made up of panels, each representing a specific aspect of the data story you want to convey. Each panel consists of a query, defining the data you wish to display, and a visualization, defining how the data is presented.

Task: Build a Simple Grafana Dashboard

• In the sidebar, hover your cursor over the Create (plus sign) icon and then click "New Dashboard".

• Click "Add visualization" and select Prometheus as your data source.

• In the Query editor below the graph, enter the below query and then press Shift + Enter:

 100 - (avg by(instance) (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100)

This query calculates the CPU usage percentage by subtracting the average idle CPU time (node_cpu_seconds_total) from 100.

• In the Panel editor on the right, under Settings, change the panel title to “CPU Usage Percentage”.

• Click "Apply" in the top-right corner to save the panel and go back to the dashboard view.

• Click the "Save dashboard" (disk) icon at the top of the dashboard to save your dashboard.

• Enter a name in the Dashboard name field and then click Save.
