Expand description

Records events as they are observed by a node.

Tracing events isn’t useful under normal operation. It can aid in understanding when and how inconsistencies were introduced. As such, some tests set a tracer so that they can emit a trace if they fail.

See NodeBuilder::traced_by.

Required Methods

A promise was made.
