Heatmap Widget

Example heatmap graph visualization

The heatmap widget shows metrics aggregated across multiple tags. Use heatmap widgets to visualize OpenTelemetry histograms, distribution metrics, high resolution and data display.

Setup

Configuration

Configure your metric query as usual. Graph OpenTelemetry histograms by using the ‘counters’ histogram mode.

Make a selection in the “avg/max/min/sum by/etc.” control to see your data across the associated tags.

Options

Y-axis controls

Y-axis controls are available through the UI and the JSON editor.

They allow you to:

  • Clip the y-axis to specific ranges.
  • Automatically change y-axis bounds based on an absolute value threshold. This threshold can be applied to one or both ends of the graph (lower and upper) to remove the “outlier” series.
  • Change the y-axis scale from linear to log, pow, or sqrt.

Change the Y-axis scale by expanding the Y-Axis Controls button.

The following configuration options are available:

OptionRequiredDescription
Min/MaxNoSpecify the minimum and / or maximum value to show on y-axis. It takes a number or Auto as the default value.
ScaleNoSpecifies the scale type. Possible values:
- linear: A linear scale (default)
- log: A logarithmic scale
- pow: A Power of 2 scale (2 is default, modify in JSON)
- sqrt: A square root scale
Always include zeroNoAlways include zero or fit the axis to the data range. The default is to always include zero.

Note: Because the mathematical log function doesn’t accept negative values, the Datadog log scale only works if values are of the same sign (everything > 0 or everything < 0). Otherwise an empty graph is returned.
