Constant Summary

CLIENT =

"CLIENT"

SERVER =

When present, “timestamp” is the moment a producer sent a message to a destination. “duration” represents delay sending the message, such as batching, while “remote_endpoint” indicates the destination, such as a broker.

Unlike CLIENT, messaging spans never share a span ID. For example, the CONSUMER of the same message has “parent_id” set to this span’s id.

"PRODUCER"

CONSUMER =

When present, “timestamp” is the moment a consumer received a message from an origin. “duration” represents delay consuming the message, such as from backlog, while “remote_endpoint” indicates the origin, such as a broker.

Unlike SERVER, messaging spans never share a span ID. For example, the PRODUCER of this message is the “parent_id” of this span.
