We've been running big brother for some years, and we monitor several hundred servers in 2 data centers.

We are currently running a pilot of xymon (4.3.0 svn), and just as with big brother, we have redundant monitoring servers. A xymon server in california monitors hosts in both california and arizona, and a xymon server in arizona monitors hosts in both data centers as well.

For the most part, xymon is performing well, but it is a bit of an annoyance with xymon that we get duplicate notifications, as each xymon server sends it's own notifications for every event.

Big brother sends a single notification for each event, as controlled by the alerting failover.

Is there any way to eliminate the duplicate notifications from xymon?
