Edge Delta Aggregation Event Widget

Overview

After selecting a type, the options open in the Filter pane. In this example, Event is selected.

You can filter the contents of an Event Widget using the filters pane, similarly to filtering on the Events page. This includes filtering by the Event Type, Monitor, Custom Facets you have configured already, and by variables present on your dashboard.

Data Sources

You select Monitor or Kubernetes in the Event Domain to choose which type of events to include in the graph.

Next, you configure the source options. You can do this on the Edit tab or the Source tab. The Edit tab enables you to manually select filters, while the Source tab enables you to paste a search query, for example one copied from the Event Explorer. As you select options on the Edit tab, a query is built on the Source tab.

On the edit tab, you can select the following filters

• Aggregation: specify how numeric data is calculated and summarized.
• Query: specify an event search query or reference a query or string variable.
• Group By: You can group the events by available facets including Custom Facets, and you can select a facet variable to group by dynamically depending on the dashboard user’s selection.

On the Compare to tab you can add a historical series for the selected data source. This series can show a particular look-back period or it can show the previous time range for currently selected look-back period:

Visualization Options

Click Visualization Options to configure how data is presented. For example you can specify whether to show the Legend, the data format of the series, and custom colors per data series.

Add Series Colors You can specify colors for the graphs using the Coloring method options:

• Auto: This option chooses a palette depending on the widget type.
• Default palette: This option uses the built-in Edge Delta color palette that is designed for readability and to work with the interface colors.
• Random palette: This option uses randomly selected colors for each series.

• Custom palette: You can use this option to choose a set of colors which are assigned sequentially to the series. Right click to remove a color.

• Continuous color mapping: This option changes series colors on a gradient depending on its y-axis value. You set the value range and colors. This is useful for visualizing gauges and indicating a threshold.

• Discrete color mapping: This option is similar to Continuous but you set intervals and colors for each interval. The colors do not change in a gradient but rather switch as the series passes the interval.

Rather than using preset templates you can configure specific colors for specific series in the charts. To do this expand the Style overrides section and create a new item for each series, then specify a Fixed color:

Display Options

Click Display Options to configure the widget labels, a tooltip and footer text. You can set the Time Filter to either inherit from the parent dashboard, or you can set a custom look back period.
