Configure a top-list visualization in Dynatrace

Shows query results as a top list.

Example top list

Select a different metric

By default, this visualization shows the first metric of a multi-metric query.

To select a different metric from a multi-metric query, select the letter next to the metric you want to visualize. In this example, you would change the selection from A (CPU usage %) to B (Memory used %).

Visual settings

Visualization

You must select Top list to display this type of visualization.

Fold transformation

The fold transformation combines a data points list (a timeseries: a collection of data points over the time period) into a single data point.

  • The default fold transformation is Auto, which automatically selects the most appropriate time aggregation based on the metric.
  • You can manually override Auto with any of the following: Last value, Average, Count, Maximum, Minimum, Sum, Median, Value, Percentile 10th, Percentile 75th, Percentile 90th.
  • If you need to see the last reported value for a metric (rather than an aggregation), select Last value.

Per-metric visual settings

Rename a metric

You can change the name of a metric as it is displayed on the chart and in the chart legend. The query definition retains the metric's original name.

  1. In the Visual settings section, select Edit pen icon for the metric you want to rename.
  2. Edit the name, and then select the checkmark to save the new name.

Unit and Format

Use the Unit and Format settings to determine how your data is displayed.

Unit

Use the Unit setting to set the unit in which the metric is displayed.

  • None = No unit displayed
  • Auto = Dynatrace selects an appropriate display unit
  • Other selections specify the exact unit to display. The options here depend on the metric's unit. A time metric, for example, offers alternative units for displaying time.
  • To add a custom unit/suffix string, type the custom string in the Unit box and then select it from the list.

Format

Use the Format setting to configure the number of decimal places displayed for the selected metric.

  • None = No formatting.
  • Auto = Dynatrace selects an appropriate format. For example, where None would display 5.062357754177517 %, Auto would display 5.06 %.
  • Other selections specify the number of decimal places to display: 0, 0.0, 0.00, 0.000

Examples

Example: bytes

When the basic unit of the metric is byte:

  • If you set Unit to Auto, Dynatrace automatically expresses the results in a human-readable unit, which in this case could be GiB.
    Note: A byte-based unit can have either a binary or decimal base, which will determine whether Dynatrace selects, for example, GiB or GB. If no base is defined in the metric itself, a decimal base is used.
  • If the automatically selected unit isn't suitable in your case, you can force Dynatrace to express the same values in a specific unit (Unit = B, KiB, or MiB).
  • If you want to see raw data (no conversion), you can set Unit to None and see the results in the basic unit of the metric (which in this case is bytes).
Example: dollars and cents

When the basic unit of a metric is dollars and cents:

  • For smaller values, to see the results expressed in exact dollars and cents: set Unit to Auto, and set Format to 0.00 (to have two decimal places for the cents)
  • For larger values, to see the results expressed in thousands, millions, or billions of dollars and no cents: set Unit to k, mil, or bil, and set Format to 0 (to see nothing after the decimal point).
Example: exact counts

When the basic unit for the metric is a count:

  • To see an exact count: set Unit to Auto, and set Format to None.
  • To see a rough count: set Unit to something like k, mil, or bil (depending on the magnitude of your values), and set Format to 0.0, 0.00, or 0.0000 (depending on how many decimal places make sense in combination with the selected Unit setting).
Example: thresholds

When setting threshold values:

  • If you select a Unit (for example, MiB), the Threshold settings are then prepared to match the selected unit, so you just need to enter threshold values without specifying MiB.
  • If you set Unit to Auto (to let Dynatrace automatically scale the displayed output), you still need to set Threshold values in a specific unit such as bytes.

Add color override

To force a different color (override the color palette) for a specific series such as a selected host

  1. In the Visual settings section, select Add color override
  2. Select the series from the list
  3. Select the override color for that series

Thresholds

To enhance your visualizations, you can set thresholds that are reflected in your visualization.

Set thresholds

To enhance your visualizations, you can set thresholds that are reflected in your visualization.

This example shows a Graph visualization of CPU usage % (builtin:host.cpu.usage) before and after adding thresholds. The effect is similar for other visualizations with thresholds.

The thresholds also affect how the tiles are displayed on your dashboards.

Set thresholds

Tip: Set Threshold values after you set Unit:

  • If you set Unit first, the threshold settings are prepared to match the selected unit.
  • If you change Unit after you set threshold values, the threshold values are not automatically adjusted to match the new unit setting.

To set thresholds

  1. In the Thresholds section, enter threshold values

    Set threshold values

  2. Adjust threshold colors optional

Hide or show threshold colors

To hide or show threshold colors without deleting the threshold settings, in the Thresholds section, select Preview.
