The endpoint [http://localhost:8222/streaming/isFTActive](http://localhost:8222/streaming/isFTActive) indicates, through the HTTP response code, if this server is running as the active server of a fault tolerant (FT) group. If the server is the active server, the HTTP response code returned is 200, otherwise 204 (which indicates either that the server is running as a FT standby server, or simply not running in FT mode).
