In today's tutorial, we'll delve into creating powerful dashboards that offer insightful visualizations of your data. Dashboards provide an at-a-glance view of your metrics and are essential for tracking key performance indicators (KPIs) effectively. We'll learn the theory behind dashboard creation and follow it up with precise practical tasks to solidify your understanding.
Theory: Anatomy of a Dashboard
Panels: These are the building blocks of a dashboard, each representing a specific aspect or metric. A panel typically consists of a query and a visualization.
Query: The query defines the data you want to display in a panel. It fetches the relevant data from your data source based on specified parameters.
Visualization: This determines how the data fetched by the query is presented. Visualizations can range from simple line graphs to more complex heatmaps or pie charts.
Practical Tasks:
Task 01: Creating a Traffic Panel
Open Dashboard:
- Hover over the Create icon in the sidebar and click Dashboard.
Add a New Panel:
Click on the Add a new panel option.
Enter Query:
In the Query editor, input the following query:
sum(rate(prometheus_http_request_duration_seconds_count{job="prometheus"}[5m])).
Press Shift + Enter to execute the query.
Update Legend:
In the Legend field, enter
{{route}}to rename the time series in the legend.
Click outside the field to update the graph legend.
Adjust Panel Settings:
In the Panel editor on the right, under Settings, change the panel title to “Traffic”.
Save Panel:
Click Apply in the top-right corner to save the panel and return to the dashboard view.
Save Dashboard:
Click the Save dashboard icon at the top and enter a name in the Dashboard name field.
Finally, click Save to save your dashboard.
Congratulations! You've successfully created a panel to visualize traffic metrics on your dashboard.
Conclusion:
Creating dashboards empowers you to monitor and analyze data effectively. By understanding the components of a dashboard and following practical tasks like the one outlined above, you can build informative dashboards tailored to your specific needs.
