### Enabling To enable the monitoring server, start the NATS Streaming Server with the monitoring flag -m (or -ms) and specify the monitoring port. Monitoring options ``` -m, --http_port PORT HTTP PORT for monitoring -ms,--https_port PORT Use HTTPS PORT for monitoring (requires TLS cert and key) ``` To enable monitoring via the configuration file, use `http: "host:port"` or `https: "host:port"`. There is no explicit configuration flag for the monitoring interface. For example, after running this: ``` nats-streaming-server -m 8222 ``` you should see that the NATS Streaming server starts with the HTTP monitoring port enabled: ``` (...) [53359] 2017/12/18 17:44:31.594407 [INF] Starting http monitor on 0.0.0.0:8222 [53359] 2017/12/18 17:44:31.594462 [INF] Listening for client connections on 0.0.0.0:4222 (...) ``` You can then point your browser (or curl) to [http://localhost:8222/streaming](http://localhost:8222/streaming)
