I’m setting up the parent-child relationships for my network devices, and I’ve ran into a bit of a conundrum. I have switches that are linked together in a loop, to allow for multiple paths in the event of a port or cable failure of course. However, if I try to set these up in Nagios as they are physically connected, I will end up with switch A depending on switch B, AND vice versa. I’d like the 2-D map to accurately reflect the layout, and would like the reachability logic to function. I realize I may be getting a little bit beyond availability monitoring which is Nagios’ forte, and I may look at Weathermap for link monitoring. This bugs be though. Also, it would be nice if a host could depend upon a service (say, an SNMP ifOperStatus of a particular port).
Any suggestions or workarounds? Thanks a million.
