Single value visualizations

Use single value visualizations to display data generated from search queries, trends over time, and at-a-glance status updates.

Single value

A single value can be a count or other aggregation of distinct events. The following are common use cases for single values:

• key performance indicators or metrics
• aggregate events
• specific strings

Apply dynamic coloring to single values for trend, sparkline stroke, major values, and background. For example, use the following search to create a single value.

index = _internal | timechart count | head 5

You can then configure the visualization with dynamic coloring for sparkline and trend, which will generate a single value with an area chart and bolded trend line.

Single value icon

You can add icons to single values to help signal significant changes and clarify what the single value represents. This is useful when the icon accurately represents the data, and you don't want to use a visualization title or description to explain the metric.

For example, the following steps create a single value icon visualization.

1. Make sure you're in Absolute layout. Single value icons only work in the absolute layout.
2. Add an icon by choosing an icon from the Add Icons dropdown menu ( ).
3. Enter the following search query.

   index = _internal source = "*splunkd.log" log_level = "error" | stats count

4. Enable the Major Value and Trend toggle.
5. Select Icon & Major Value from the Dynamic Elements dropdown in the Coloring section.

Single value radial

Add a radial visualization to a single value to help illustrate progressive change or percentage of completeness. For example, use the following search to create single value radial visualization.

index = _internal | timechart count | table count

You can then configure the visualization with dynamic coloring and a maxValue to show the percentage of completeness.

A caption, unit notation, and range colors emphasize the returned value. If you use the timechart command, a trend indicator is shown beneath the visualization to show how data has changed over time. For more details, see Use timechart to generate a single value and trend indicator.

Data formatting

Single value visualizations work best for queries that aggregate data using the stats command or create a time series chart using the timechart command. In particular, a single value's sparkline depends on data generated from the timechart command.

Use timechart command to generate trend indicator

To access trend indicators, your search must include the timechart command. Using timechart means that time series data becomes available to trend indicator processing. When you use the timechart command, instead of the stats command, the first column of results is the field _time. Use the table command to ensure the fields sort, so the value you want returned is in the first column.

For example, the following search will display count column as the major value, which is the number of log_level errors in some specified time range.

index=_internal source="*splunkd.log" log_level="error" | timechart count | table count _time

The resulting single value visualization will have an upward or downward arrow indicating the trend and the value of change.

Generate a single value visualization

1. Select the Add chart button ( ) in the editing toolbar and browse through the available charts. Choose the single value visualization.
   1. Add an icon by choosing an icon from the Add Icons dropdown menu ( ) and enabling the Major Value and Trend toggle. Icons only work in the Absolute layout.
2. Select the visualization on your dashboard to highlight it with the blue editing outline.
3. Set up a new data source by selecting + Create search and adding a search to the SPL query window. Or, you can select an existing data source under the Search, Saved search, or Chain search sections.
4. (Optional) You can also write a new ID that describes the search better than the default by changing the ID in Data source name.
5. Select Apply and close.

Configuration panel options for single value visualizations

You can use the Configuration panel to configure the following components.

Title (single value and single value radial)

Give your visualization a title. This is also helpful when searching for individual visualizations in the dashboard definition. This name is not the same as the automatically assigned unique ID.

Description (single value and single value radial)

Give your visualization a description to explain what the user is viewing.

Data Sources

Choose an existing search or create a new one.

Position & Size

You can use your mouse to change the size or location of the visualization panel, or the Position & Size section of the Configuration panel for sizing by pixel and for placement on the canvas.

Selected Data Field (single value)

Use the dropdown menu to select the field value from your search results that will be displayed as the major value.

Major Value & Trend (single value)

• Use the Unit Position dropdown menu to place a unit string before or after the major value.
• Use the Unit Label field to specify a unit using a string.
• Use Precision to choose the number of decimal places displayed.
• Use the Major Value Size (px) field to change the display size of the major value in pixels.
• Use Trend Display to choose to show the trending value as either a percent or an absolute number. You can also choose to remove the trend value from the visualization.
• Use the Trend Size (px) field to change the display size of the trend value in pixels.

Major Value & Trend (single value icon)

• Toggle the Enable switch to add a major value and a trending value to an icon.
• Use the Unit Position dropdown menu to place a unit string before or after the major value.
• Use the Unit Label field to add a unit using a string.
• Use Precision to choose the number of decimal places displayed.
• Use Major Value Size (px) to change the display size of the major value in pixels.
• Use Trend Display to choose to show the trending value as either a percent or an absolute number.
• Use Trend Size (px) to change the display size of the trend value in pixels.

Major Value & Trend (single value radial)

• Use the Unit Position dropdown menu to place a unit string before or after the major value.
• Use the Unit Label field to specify a unit using a string.
• Use Precision to choose the number of decimal places displayed.
• Use Trend Display to choose to show the trending value as either a percent or an absolute number. You can also choose to remove the trend value from the visualization.

Sparkline (single value)

Configure your sparkline.

• Off removes your sparkline
• Before places the sparkline to the left of the single value
• Below places the sparkline beneath the single value
• After places the sparkline to the right of the single value

Coloring

Use the Coloring section to set colors that will apply to value ranges returned by search-generated data sources.

Dynamic Elements There are multiple options to choose from for each single value visualization. Use the Dynamic Elements dropdown menu to select the visualization elements you want for color thresholding. After you've selected, the elements will populate in the configuration panel for further color formatting. For more information, see Add dynamic options to visualizations.

Interactions

Click + Add Drilldown to allow a user to click the value of a visualization to link to an external or internal URL.

Code

Select your visualization or its search to view and edit the source code in real-time. You can also change the Visualization ID to a more readable ID to help identify this visualization in the source code.

Add emphasis to a returned value using dynamic formatting

A caption, a unit notation, and threshold coloring emphasize the returned value. If you use a command that returns multiple fields or values, you can use the Major Value & Trend section in the Configuration panel to add a trend indicator and a sparkline (single value only) to show how data values compare.

Add dynamic coloring in several ways. For example, the following search uses the timechart command to track daily errors for a Splunk deployment and displays a trend indicator and sparkline.

index=_internal source="*splunkd.log" log_level="error" | timechart count

You can apply color thresholding to both the major value and the trend indicator.

For more information, see Add dynamic options to visualizations.

Source options for single value visualizations

While you can use the visual editor to set most of the options, there are additional options, such as coloring the area under the sparkline, that can only be set in the source editor for splunk.singlevalue, splunk.singlevalueicon, and splunk.singlevalueradial. These options are added to the options field of the visualization stanza. The following example shows a single value visualization with a dynamically colored major value and trend value. It also has a sparkline and a static background color.

Use the following search to reproduce the example.

index=_internal source="*splunkd.log" log_level="error" | timechart count
