We've created a bunch of fakes interfaces on devices that interconnect sites. For each link, the 2 nodes located on extremities have a fake interface with IP’s on a 127.0.0.0/30 network (127.0.0.0/30, 127.0.0.4/30 and so on). Only these networks have the "zDrawMapLinks" property set to "true".
Everything works fine for sites with only 1 link. If an end-point of a link goes down, only the related link goes down on the map.
However, we’ve sites connected to multi-sites and, when one devices goes down, even links located on other networks not related with the faulty device are appearing on a down state (red) on the map.
Does somebody else are experiencing the same problem?
We're using zenoss 3.2.1 on a centos.
From the administrator manual:
On "locations" topic:
The color of the line will represent the highest severity of any events affecting the connection. These are determined by:
On our case, there's no ping down or other critical state at either end of the connection nor any event on the interfaces.
Are there suppressed event on any of the associated devices? I don't recall if these events cause WAN line updates on the map, but if they do there's a good chance your event console isn't showing suppressed state events.
We haven't suppressed any event on the associated devices where the links should be on a green state.
I've a question: could the link be represented down because the layer 3 dependecy of any of the associated device be down?
