Monitoring replication
Storage Mirroring offers a variety of methods for monitoring Storage Mirroring mirroring. Statistics include information like
connection up-time, target status, bytes queued or sent, and so on. The informational data includes processing notifications,
warnings or errors. Below is a brief description of how four of the monitoring methods are applicable to the Storage Mirroring
connection. For detailed information on these and other monitoring methods, see
Monitoring Tools on page 13-1.
! Text Client—The Storage Mirroring Text Client window displays a minimal number of statisical and informational data
on screen.
! The DTCL status command displays statisical and informational data. Identify the connection ID by locating the number
in the left column of the Text Client window and use the status command to display the information.
! LogViewer—LogViewer is a utility within Storage Mirroring that gathers Storage Mirroring alerts and information
messages. Alerts are proccessing notifications, warnings, and error messages. For detailed steps on how to use
LogViewer, see
LogViewer on page 13-35.
! DTStat—DTStats is a utility that takes snapshots of Storage Mirroring statistical data and writes the information to a file.
For detailed steps on how to use DTStat, see DTStat on page 13-26.
Replicating permissions by name
1. To determine the permissions setting, use the get command with the ReplicateNTSecurityByName option.
2. To modify the permissions setting, use the set command with the ReplicateNT SecurityByName option. By

replicated to the target. You will want to enable this feature if you are using local security groups.

replicated to the target. You will want to disable this feature if you are using domain security groups.
