About Charts

Last updated on 26 January, 2023

Dashboards are central in Dexda as a starting point from where you can quickly get a situation overview. Dashboards visualize data using charts of different types. Charts get their information from different data sources and types such as insights, alerts, and events. You can add filtering to charts, to customize the visualization output for specific purposes and user groups.

The following describes the concepts of charts and data filtering. For information on how to create dashboards, see Creating Dashboards. For information on how to view and act on dashboard information, see Using Dashboards.

Note: You need administration permission to manage charts on dashboards.

Chart Types

A chart provides a mechanism to query data and display it for consumption in a supported chart type. These provide numerous options to create summaries of aggregated statistics, as well as detailed data views. You can for example create a Ticker type of chart showing the number of priority-one alerts for customer-facing applications. Or you can create a Grid (table) type of chart displaying event details.

The following main data sources are available for querying when configuring customized charts:

  • Insights: Alerts created from automated machine learning.
  • Alerts: Alert records created from matched rules.
  • Events: Processed event records.

Supported chart types for the different data source types are described in the following.

Grid Chart

The grid type of chart displays source data in table format, for example a list of uncorrelated alerts.

Configuration options for a grid chart include the following:

  • Title: The name of the chart as displayed on the dashboard.
  • Columns: Columns selected from the column selector.
  • Filter: Option to add filter expressions to limit the query. If no filter is added, all events/alerts/insights will be shown.

For more information about filters and how to use them, see About Filters and Creating Filters.

Ticker Chart

The ticker chart type shows aggregations as count values, for example the total number of open insights or uncorrelated alerts.

Configuration options for a ticker chart include the following:

  • Title: The name of the chart as displayed on the dashboard.
  • Field: Data available for the ticker. Options here vary depending on type of data source.
  • Aggregation: Operators include MIN, MAX, SUM, MEAN, and COUNT.
  • Filter: Option to add filter expressions.

For more information about filters and how to use them, see About Filters and Creating Filters.

Aggregation Chart

Configuration options for an aggregation chart include the following:

  • Title: The name of the chart as displayed on the dashboard.
  • Group: You can group the aggregation for example by resource or tenant ID. Options vary depending on type of data source.
  • Field: Data available for the aggregation. Options vary depending on type of data source.
  • Aggregation: Operators include MIN, MAX, SUM, MEAN, and COUNT.
  • Filter: Option to add filter expressions.

For more information about filters and how to use them, see About Filters and Creating Filters.

Time Series Chart

The time series type of chart shows aggregation by time range, for example number of events received during a specific time range.

Configuration options for a time series chart include the following:

  • Title: The name of the chart as displayed on the dashboard.
  • Group: Options vary depending on type of data source.
  • Field: Data available for the aggregation. Options vary depending on type of data source.
  • Aggregation: Operators include MIN, MAX, SUM, MEAN, and COUNT.
  • Filter: Option to add filter expressions.

For more information about filters and how to use them, see About Filters and Creating Filters.

Filters

Dexda has a shared filter component that lets you define a query filter in a consistent way across applications like charts, rules and actions. When adding charts and building queries and aggregations to limit results, you have a number of fields to chose from. Available fields vary depending on the selected data source – events, alerts, or insights, for the chart. See About Filters and Creating Filters.
