20 Pie chart

Description

These parameters and the possible property values for the respective dashboard widget field objects allow to configure the Pie chart widget in dashboard.create and dashboard.update methods.

Widget fields properties are not validated during the creation or update of a dashboard. This allows users to modify built-in widgets and create custom widgets, but also introduces the risk of creating or updating widgets incorrectly. To ensure the successful creation or update of the Pie chart widget, please refer to the parameter behavior outlined in the tables below.

Parameters

The following parameters are supported for the Pie chart widget.

Parameter type name value
Refresh interval 0 rf_rate 0 - No refresh;
10 - 10 seconds;
30 - 30 seconds;
60 - (default) 1 minute;
120 - 2 minutes;

900 - 15 minutes.

Data set

The following parameters are supported for configuring a Data set.

The first number in the property name (e.g. ds.0.hosts.0, ds.0.items.0) represents the particular data set, while the second number, if present, represents the configured host or item.

When configuring the widget on a template dashboard, only items configured on the template should be set.

Note: To configure multiple items, create a dashboard widget field object for each item with an incremented number in the property name.

Parameter behavior:

Items (Widget) 1 ds.0.itemids.0._reference Instead of Item ID:
ABCDE._itemid - set a compatible widget (with its Reference parameter set to "ABCDE") as the data source for items.

Note: To configure multiple widgets, create a dashboard widget field object for each widget with an incremented number in the property name.

Examples

The following examples aim to only describe the configuration of the dashboard widget field objects for the Pie chart widget. For more information on configuring a dashboard, see dashboard.create.

Configuring a Pie chart widget

Configure a Pie chart widget in the following way:

  • 2 data sets for a total of 9 items on 1 host.
  • The first data set is of type "Item list" and consists of 3 items that are all with type "Normal" and represented by a different color.
  • The second data set is of type "Item patterns", consists of 6 items, has a configured aggregation for each item, and is represented by a custom color.
  • The second data set also has a custom data set label.
  • Data in the pie chart are displayed as a doughnut chart with a custom width and total value with units in the center.
  • Data in the pie chart are displayed and aggregated for a custom time period of the last 3 hours.
  • Pie chart legend displays configured items in 4 rows.
