Serilog Graylog cannot log in Graylog

Question

I am new to graylog. I cannot log into graylog. When I do a search for the message, I look for source:xxx-yyy or just a keyword test9999, look for all the latest logs, my message is not there. What could I be doing wrong?

Server name and port are correct.

LoggerConfiguration loggerConfiguration = new LoggerConfiguration();
         
         loggerConfiguration
            .Enrich.FromLogContext()
            .Enrich.WithProperty("source", "xxx-yyy")
            .Enrich.WithProperty("test", "test9999");

         loggerConfiguration.WriteTo.Graylog(new GraylogSinkOptions
         {
            HostnameOrAddress = "server",
            Port = 12201,
            TransportType = TransportType.Udp,
            MinimumLogEventLevel = LogEventLevel.Information,
            Facility = "local2",
            ShortMessageMaxLength = 12000,
            StackTraceDepth = 10,
            MessageGeneratorType = MessageIdGeneratorType.Timestamp
         });

Answer 1

The problem was the Stream was not setup in the server. So the solution was to setup a stream with a certain rule (that I had to add a field for), and I had to be allowed to access this stream.
