Getting HTTP 404 response when logging from asp.net core 6.0 app to local Seq server (localhost:5341-CodePudding

Running this test on MacOS.

Getting the following error when logging to Seq http endpoint.

2022-04-17T00:46:06.4931040Z Exception while emitting periodic batch from Serilog.Sinks.Http.Private.Sinks.HttpSink: Serilog.Debugging.LoggingFailedException: Received failed result NotFound when posting events to http://localhost:5341

Here is the asp.net core 6.0 code snippet that's attempting to log to seq URL. Seq is running locally in docker (http://localhost:5341/ url show sup the dashboard on safari)

    using var log = new LoggerConfiguration()
    .WriteTo.Http(requestUri:"http://localhost:5341")
    .CreateLogger();
    
    Serilog.Debugging.SelfLog.Enable(Console.Error);
   
    log.Information("hello from serilog");

If I try to use the follwoing seq cli command (from terminal) to log a message on the same endpoint , it works just fine. I am not sure why I am getting the http 404 when trying to do the same from c# asp.net core app.

docker run --rm --net host datalust/seqcli:latest log -m Hello2 -s http://localhost:5341

Here is the intercept from wireshark showing the http 404 response.

Update:

While the Seq server is running in docker. The asp.net core test app is running on the local macOS terminal. using command dotnet run

CodePudding user response：

Was missing this package dotnet add package Serilog.Sinks.Seq

Figured to log to Seq need to use WriteTo.Seq("http://localhost:5341") instead of WriteTo.Http(requestUri:"http://localhost:5341").

This fixed the issue.
