Create a timeline query

To generate a timeline, use a search that returns results in the correct data format.

Query syntax

To generate a timeline visualization, use this search syntax.

... | table _time  <resource_field> [<color_field>] [<duration_field>] 


Query components

A timeline search includes the following components.

_time

  • Required
  • Indicates event start time.


resource_field

  • Required
  • Indicates the resource or category to plot on the timeline.


color_field

  • Required for visualizations using sequential or categorical colors.
  • Determines colors for events and activity intervals.
  • If you are not using colors in the visualization, leave this field out of the query.


duration_field

  • Optional
  • Use durations measured in milliseconds.
  • Indicates the activity duration.
  • Can be generated by the transaction command.
Note: The transaction command returns a duration in seconds. Use the following eval command to convert the value to milliseconds.
...| eval duration = (duration * 1000) 

Search result data formatting

A timeline search returns results formatted as a table with multiple columns.

Check the Statistics tab after running a search to make sure that the results table includes the required columns in the following order.

Results table columns

First Second Third Fourth
_time Resource Color (required for categorical or sequential colors) Duration (optional)


Example query

Here is part of a search tracking weather events in different regions.

... | stats count by _time, duration, "NERC Region", "Event Description" | table _time "NERC Region" duration

The search generates the following results table.
