update the route-emitter metrics docs
| Metric | Description | Unit |
| ------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | ---- |
+| `RoutesTotal` | Number of (http and tcp) route associations (`external routes * backend instances`) in the route-emitter's routing table. Emitted periodically every emit cycle. | number |
+| `HTTPRouteCount` | Number of (http and tcp) route associations (`external routes * backend instances`) in the route-emitter's routing table. Emitted periodically every emit cycle (only in local mode). | number |
+| `TCPRouteCount` | Number of exposable ports (i.e. container ports) in the routing table. Emitted periodically every emit cycle (only in local mode). | number |
| `AddressCollisions` | Number of detected conflicting routes. A conflicting route is a set of two distinct instances with the same IP address on the routing table. | number |
-| `LockHeld.` `v1-locks-route_emitter_lock` | Whether a route-emitter holds the route-emitter lock: 1 means the lock is held, and 0 means the lock was lost. Emitted periodically by the active route-emitter. | 0 or 1 (boolean) |
-| `LockHeldDuration.` `v1-locks-route_emitter_lock` | Time the active route-emitter has held the route-emitter lock. Emitted periodically by the active route-emitter. | ns |
| `MessagesEmitted` | Cumulative number of messages the route-emitter sends over NATS to the gorouter. | number |
-| `RouteEmitterSyncDuration` | Time the active route-emitter took to perform its synchronization pass. Emitted periodically. | ns |
-| `RoutesRegistered` | Cumulative number of route registrations emitted from the route-emitter as it reacts to changes to LRPs. | number |
-| `RoutesSynced` | Cumulative number of route registrations emitted from the route-emitter during its periodic route-table synchronization. | number |
-| `RoutesTotal` | Number of routes in the route-emitter's routing table. Emitted periodically. | number |
-| `RoutesUnregistered` | Cumulative number of route unregistrations emitted from the route-emitter as it reacts to changes to LRPs. | number |
+| `RouteEmitterSyncDuration` | Time the route-emitter took to perform its synchronization pass. Emitted periodically. | ns |
+| `RoutesRegistered` | Cumulative number of NATs route registrations emitted from the route-emitter as it reacts to changes to LRPs. | number |
+| `RoutesUnregistered` | Cumulative number of NATs route unregistrations emitted from the route-emitter as it reacts to changes to LRPs. | number |
+| `RoutesSynced` | Cumulative number of route **registrations** emitted from the route-emitter during its periodic route-table emission. | number |
| `ConsulDownMode` | Whether the route-emitter is able to connect with the consul correctly | 0 or 1 boolean |
-| `HTTPRouteCount` | Number of HTTP Routes in the route-emitter's routing table. Emitted periodically and only on local mode. | number |
-| `TCPRouteCount` | Number of TCP Routes in the route-emitter's routing table. Emitted periodically and only on local mode and when tcp enabled. | number |
+| `LockHeld.` `v1-locks-route_emitter_lock` | Whether a route-emitter holds the route-emitter lock: 1 means the lock is held, and 0 means the lock was lost. Emitted periodically by the active route-emitter. | 0 or 1 (boolean) |
+| `LockHeldDuration.` `v1-locks-route_emitter_lock` | Time the active route-emitter has held the route-emitter lock. Emitted periodically by the active route-emitter. | ns |
