Under Monitored FRS replica sets, click Add/Remove
Replica Sets.
Under Domain, choose the domain that contains the
replica sets you want to monitor.
The list of domains includes all domains trusted by the forest
where the console is installed. You can also type in a domain name
that is externally trusted.
Under FRS replica sets, click the replica set, and then
click Add.
After you click OK, you are prompted to choose the
servers on which to install providers. Select the option you
prefer.
If you want to collect data from the providers immediately
after they are installed, click Collect initial data from WMI
providers after installation. For more information about the
initial provider deployment, see Monitoring FRS Using
Ultrasound.
