Prometheus (1)Summary
Binary indicator (0 or 1) showing whether this device is currently operating as an active exit node for other tailnet members. Exit nodes route internet traffic for connected peers. Value of 1 indicates the device is accepting exit node connections and routing traffic, while value of 0 means it's not serving as an exit node. Critical for tracking exit node availability and preventing single points of failure.

Exit node routing failure disrupting traffic flowcritical
When an exit node goes offline or becomes unreachable while devices are configured to route through it, network connectivity for those devices is disrupted. This represents a single point of failure for devices relying on exit node routing for internet access or specific network segments.
