In this lesson, we also talked about how to use the replication monitor, replication agent job history, and the Msrepl_Errors table to find out replication issues.

This lesson also talked about how to measure replication latency using the tracer tokens in the replication monitor.

In the next lesson, we'll talk about AlwaysOn high availability and disaster recovery.
