MMS alerting from another tree

Hi,

Is it possible for my MMS server in one tree to monitor servers in another
tree? I've set it all up and even created a rule (ZfS7) to trigger all
alerts for the host address in the remote tree but it doesn't appear to be
working?

All IP traffic is currently configured to pass from the MMS server to the
host address so it's not a firewall/ACL issue.

Will I need to install another site server in the remote tree?


Thanks in advance,
Carl Francis.
