Has anyone else had a need to monitor which uplink interface is currently 'Active'? If so, what was your method for accomplishing it?
The current issue we're facing is that our 4G failover simply works too well. We're finding sites that have had their primary cable/DSL/whatever circuit offline for days without anyone realizing it. We're looking at 700+ sites equipped with MX's and a 4G USB failover device, so this can amount to thousands in charges on our Verizon bill. There are definitely ways to get this information and I understand that, we're just having a hard time molding it to our needs.
For example, we could use the built-in alert 'The primary uplink status changes' on the template level and fire off an email to our ticketing system, however we don't necessarily care about an outage that only lasts 30 minutes. We could also monitor via SNMP when the primary uplink interface goes down, however that doesn't help in the case of routing troubles as the interface will still show it's up even though the MX has already failed over to the 4G interface.
Ultimately, we're looking for a way to track when the Cellular interface goes 'Active' on the MX for longer than 1 hour. We utilize Solarwinds for other monitoring, so it would be fantastic if I could find a way to do it within that.
