Now, that is technically right, but from an operational point it's more Administratively down, or should simply be ignored. Would it be possible to suggest either a general 'mark interface as failover to interface X' functionality, or could this be a special probe that has this functionality? --- end of quote --- Thanks for the good question. I have been thinking about how InterMapper should display warnings for individual interfaces, and this plays into it. There seem to be two aspects: 1) Per-interface utilization and error rate thresholds (warning/alarm/critical). These would change the halo/backgrounds on the links when the traffic exceeds the specified % utilization/error rate. 2) The ability to ignore errors, discards, and outages for each interface. They would mirror (and override) the per-device settings in the "Set Behavior" window. Open Questions: - How should alerts/notifications be tied to traffic thresholds? If traffic exceeds the link's threshold, should the device status *always* change to warning/alarm/critical? Should it always send a notification? - How should default thresholds be set? A 56kbps frame relay link would have vastly different utilization and error thresholds than a 100Mbps ethernet, which might still be different from an OC192... I think we need to apply a sensible set of defaults automatically to the various kinds of links, and make it easy for customers to change them. - Failover/backup links. In some sense, it's *good* that a backup link is down, and it might be notable if the link ever comes up - because that means that the primary link has failed. (My initial thought is that this is a special case, and should be handled by a separate "interface up" probe that alerts if the interface goes up. Once we have multiple probes per icon, these could be combined...) I welcome any feedback. Thanks!
