Parameters

ParameterDescription

Description

The until() event function returns a set of synthetic events, where each synthetic event:

  • Starts at the beginning of epoch time (Jan 1, 1970)
  • Ends at the start time of a corresponding event described by the expression.

The following diagram represents an events() query that returns 3 events (A, B, and C). Using that events() query as the input to until() produces 3 synthetic events that each end when the corresponding input event begins:

Note: Synthetic events are displayed by the query, but not stored in Wavefront.
