To display two values, the current and maximum, in Grafana, you can use a combination of queries, panels, and visualizations. Here is a general outline of the steps involved:
- Create a new dashboard or open an existing one in Grafana.
- Add a new panel to the dashboard, and select the appropriate visualization type for your data (e.g., Single Stat, Gauge, etc.).
- Configure your data source by clicking on the "Panel Title" dropdown, selecting "Edit", and then choosing your desired data source.
- Define your queries to retrieve the relevant data. Each query should return two fields: one for the current value and another for the maximum value. The specific syntax and structure of the queries will depend on the data source you are using.
- Customize the visualization settings for your panel. For example, you can specify the appropriate unit of measurement, adjust the color scheme, or set thresholds for visual impact.
- Configure the panel to display your two values. Typically, there will be settings available to specify which fields correspond to the current and maximum values in your data. Make sure to map the correct fields from the query results to these settings.
- Style and arrange the panel as desired, adjusting the size and position to fit your dashboard layout.
- Save the dashboard to persist your changes.
By following these steps, you should be able to successfully display the current and maximum values in Grafana. Keep in mind that the specifics may vary based on your data source and the desired visualization.

The purpose of repeating panels in Grafana is to display the same panel multiple times, but each with different filters or data sources applied. This allows users to compare data from different sources or filter the data in various ways for easy comparison and analysis. Repeating panels are often used when there is a need to visualize multiple similar metrics or data sets side by side in a dashboard. It helps ensure consistency and efficiency in analyzing and interpreting data.
