debug::history

note
This operator is for debugging purposes only, and should not be used in production deployments.

This operator generates a history entry in the event metadata underneath the field provided in the name config value. Data is pushed to the array as a Striong in the form: "event: <op>(<event_id>)".

This can be used as a tracepoint of events in a complex pipeline setup.

This operator manipulates a section of the event metadata.

Configuration options:

  • op - The operation name of this operator
  • name - The field to store the history on

Outputs:

  • out

Example:

define operator history from debug::history
with
op = "my-checkpoint",
name = "event_history"
end;
