AD Replication Monitoring Monitor modifies its own object in the OpsMgrLatencyMonitors container and then detects how long the change takes to propagate to all other domain controllers in the domain.
An alert is generated if replication of the change takes longer than the interval that is specified as a monitor parameter. An associated rule converts this to an alert.
The account that the MOM service runs under must have sufficient permissions to create, read, and modify objects in each monitored directory partition.
The following partitions can be monitored (adjusted by monitor parameters):
Domain directory partition
Configuration directory partition
Application directory partition
See individual alerts for details.
