Event List Widget

The Event List widget is the main way of exploring events in LogScale, as it displays events as they are ingested into LogScale, and is the default visualization on the Search UI page for events.

Think of an event as a line from a log file: you can select a portion of lines from a given search interval to be viewed in the widget, as shown in Figure 139, “Event List”.

Input Format

The table below describes the main columns that are typically displayed in the Event List.

@timestamp and @rawstring columns are displayed by default in a given format. For example, @rawstring is displayed as Log line format. However, the formatting for fields in the Event List can be changed, see Field Data Types for more information.

Field Type Description
@id string Meta field automatically generated by LogScale for all events.
@timestamp datetime The timestamp of the events is used to order events in the list.
@rawstring string The content of the line. Usually this value is automatically assigned during parsing.

Event List will list as many results as returned by the LogScale server, which defaults to the 200 most recent events of the search interval. You can increase this by using the tail() function, for example tail(1000), but this can cause performance issues in the UI if too many elements are rendered.

Keyboard Navigation

You can use the keyboard to navigate the event. Alt+Ctrl+Down and Alt+Ctrl+Up will move the selection up and down the list, while displaying the fields in the inspection panel.

Widget Properties

The following properties are displayed under General in the widget's side panel:

  • Title

    The title of the widget as displayed in the dashboard. As in the example Figure 139, “Event List”, it could be Errors Over Time.

  • Description

    The description of the chart. This is free form text supporting markdown syntax.

    This same description appears in the dashboard as a tool-tip when hovering over the question mark on top of the widget.

  • Default time

    The default current time selection defined at section or widget level within the dashboard.

  • Time selector arrows

    Click + to enter a customized jump size (in milliseconds) to use when moving the interval earlier or later in time in the widget time selector.

Click the three-dot menu icon ⋮ on the widget and select Styling to configure the following properties:

  • Column properties

    Allows configuring the properties of the selected column, as described in Column Properties.

  • Size

    Allows adjusting the width of the selected column (fit to content, fit to event list, custom).

ANSI Code Support

Attention

Feature Availability

ANSI escaping of results is only available for Self-Hosted customers, controlled by the ReplaceANSIEscapeCodes dynamic configuration variable.

In Cloud environments, ANSI code support has been removed starting from version 1.112.1. See Troubleshooting: ANSI Escape Codes Trigger a Warning for more information.

The Event List widget supports ANSI codes for colour markup and text formatting. To use ANSI codes, you must escape the ANSI markup using the hexadecimal character, either \x1B or \u0018.

The ANSI markup only works for unstructured text within the Event List, whether in the search or a dashboard. You cannot use ANSI markup within titles or other text, and ANSI codes are not interpreted for XML or JSON formatted data.

For example, setting the @rawstring to add a colorized element:

logscale
@rawstring:="Colorizing \x1B[31m some \u001B[0m text"
