[!INCLUDE SQL Server]
This procedure posts a tracer token into the transaction log at the Publisher and begins the process of tracking latency statistics.
Information is recorded:
- when the tracer token is written to the transaction log;
- when the Log Reader Agent picks it up; and
- when the Distribution Agent applies it.
This stored procedure is executed at the Publisher on the publication database. For more information, see Measure Latency and Validate Connections for Transactional Replication.
