Reference to the after() function



Returns synthetic ongoing events that start when the input events end.


eventExpression Set of events that determine the start times of the returned synthetic events.


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

  • Starts at the end time of a corresponding event described by the expression.
  • Continues indefinitely.

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

Events after

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