Gauge
Gauges are single-value visualizations that allow you to quickly visualize where a value falls within a defined or calculated min and max range. With repeat options, you can display multiple gauges, each corresponding to a different series, column, or row.

You can use gauges if you need to track:
- Service level objectives (SLOs)
- How full a piece of equipment is
- How fast a vehicle is moving within a set of limits
- Network latency
- Equipment state with set point and alarm thresholds
- CPU consumption (0-100%)
- RAM availability
Configure a gauge visualization
The following video provides beginner steps for creating gauge panels. You'll learn the data requirements and caveats, special customizations, and much more:

Supported data formats
To create a gauge visualization you need a dataset containing at least one numeric field. These values are identified by the field name. Additional text fields aren’t required but can be used for identification and labeling.
Example - One value
| GaugeName | GaugeValue |
|---|---|
| MyGauge | 5 |
This dataset generates a visualization with one empty gauge showing the numeric value. This is because the gauge visualization automatically defines the upper and lower range from the minimum and maximum values in the dataset. This dataset has only one value, so it’s set as both minimum and maximum.
If you only have one value, but you want to define a different minimum and maximum, you can set them manually in the Standard options settings to generate a more typical looking gauge.
Example - One row, multiple values
The gauge visualization can support multiple fields in a dataset.
| Identifier | value1 | value2 | value3 |
|---|---|---|---|
| Gauges | 5 | 3 | 10 |
When there are multiple values in the dataset, the visualization displays multiple gauges and automatically defines the minimum and maximum. In this case, those are 3 and 10. Because the minimum and maximum values are defined, each gauge is shaded in to show that value in relation to the minimum and maximum.
Example - Multiple rows and values
The gauge visualization can display datasets with multiple rows of data or even multiple datasets.
| Identifier | value1 | value2 | value3 |
|---|---|---|---|
| Gauges | 5 | 3 | 10 |
| Indicators | 6 | 9 | 15 |
| Defaults | 1 | 4 | 8 |
By default, the visualization is configured to calculate a single value per column or series and to display only the last row of data. However, it derives the minimum and maximum from the full dataset, even if those values aren’t visible.
In this example, that means only the last row of data is displayed in the gauges and the minimum and maximum values are 1 and 10. The value 1 is displayed because it’s in the last row, while 10 is not.
If you want to show one gauge per table cell, you can change the Show setting from Calculate to All values, and each gauge is labeled by concatenating the text column with each value's column name.
Example - Defined min and max
You can also define minimum and maximum values as part of the dataset.
| Identifier | value | max | min |
|---|---|---|---|
| Gauges | 5 | 10 | 2 |
If you don’t want to display gauges for the min and max values, you can configure only one field to be displayed as described in the value options section.
Even when minimum and maximum values aren’t displayed, the visualization still pulls the range from them.

Value options
Use the following options to refine how your visualization displays the value:
| Option | Description |
|---|---|
| Show | Set how Grafana displays your data. Choose from:
|
| Calculation | If you chose Calculate as your Show option, select a reducer function that Grafana will use to reduce many fields to a single value. For a list of available calculations, refer to Calculation types. |
| Limit | If you chose All values as your Show option, enter the maximum number of rows to display. The default is 5,000. |
| Fields | Select the fields display in the panel. |
Gauge options
Adjust how the gauge is displayed.
| Option | Description |
|---|---|
| Orientation | Choose a stacking direction:
|
| Show threshold labels | Controls if threshold values are shown. |
| Show threshold markers | Controls if a threshold band is shown outside the inner gauge value band. |
| Gauge size | Choose a gauge size mode:
|
| Min width | Set the minimum width of vertically-oriented gauges. If you set a minimum width, the x-axis scrollbar is automatically displayed when there's a large amount of data. This option only applies when Gauge size is set to Manual. |
| Min height | Set the minimum height of horizontally-oriented gauges. If you set a minimum height, the y-axis scrollbar is automatically displayed when there's a large amount of data. This option only applies when Gauge size is set to Manual. |
| Neutral | Set the starting value from which every gauge will be filled. |
Show threshold markers
Controls if a threshold band is shown around the inner gauge value band.
Text size
Adjust the sizes of the gauge text.
- Title - Enter a numeric value for the gauge title size.
- Value - Enter a numeric value for the gauge value size.
