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 132, “Event List”.

Input Format

Find in table below 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 have to be 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

Use the widget's Edit Style panel to configure the following properties.

  • Title

    The title of the widget as displayed in the dashboard. As in the example Figure 132, “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 tooltip when hovering over the question mark on top of the widget.

  • Show in context...

    You can perform a context based search, that is, see the context surrounding a specific event of your widget, by clicking the + sign next to each event, and then selecting the desired fields: the event will be shown back in the main Search UI page.
