I have a scenario where we have two ISP’s which we use for all network traffic. The primary is a T1 and the secondary is DSL. There are times when the primary gets overloaded and the secondary kicks in. People then notice slower browse times and uploads and dowloads. Only after some complaints do we realize the secondary is handling traffic. Is there a way to monitor when the secondary is handling if there is an issue with the primary? I was thinking a traceroute type of check but i dont know how that would be configured, im not a networking guru. I am already monitoring the up/down of the device.
