How will we be able to determine which of our 10,000 forwarders is down?
Hi
You should use monitoring console and enable forwarder monitoring. Then you can just check which are down.
Settings -> MC -> Forwarders -> Forwarders: Deployment.
There is also alert: DMC Alert: Missing Forwarders which you could enable.
Another way is just install e.g. Meta Woot or TrackMe app and configure those to follow up your forwarders.
