StackSpot.Logging.OpenTracing 1.0.0

StackSpot logging Extension OpenTracing

Componente projetado para complementar o log da aplicação com tracing.

Versões suportadas

• net5.0
• net6.0

Uso

1. Adicione o pacote NuGet StackSpot.Logging.OpenTracing ao seu projeto.

dotnet add package StackSpot.Logging.OpenTracing

2. Configure as variáveis.

• APP_NAME - nome da aplicação - Campo Obrigatório
• LOG_LEVEL - level de log, valores: DEBUG, INFO, WARN, ERROR, FATAL.

Quando executar na máquina local, você pode configurar as variáveis de ambientes no arquivo launchSettings.json.

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "profiles": {
    "Sample.WebApi": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "sample",
      "environmentVariables": {
        "APP_NAME": "MyAppName",
        "LOG_LEVEL": "INFO",
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "applicationUrl": "http://localhost:5000"
    }
  }
}

Você pode configurar as variáveis no arquivo appsettings.json.

{
  "AppName": "MyAppName",  
  "LogOptions": {
    "LogLevel": "Info"
  }
}

3. Adicione ao seu IServiceCollection via services.AddLogger() no Startup da aplicação ou Program.

Utilizando váriavel de ambiente

services.AddLogger()
        .WithOpenTracing();

Utilizando appsettings.json

services.AddLogger(Configuration)
        .WithOpenTracing();

Implementação

Estendemos os métodos do ILogger<> transformado o output, adicionalmente estamos provendo duas sobrecargas novas para suportar TAGs e log de Objetos no campo Data.

[ApiController]
[Route("[controller]")]
public class SampleController : ControllerBase
{
    private readonly ILogger<SampleController> _logger;

    public SampleController(ILogger<SampleController> logger)
    {
        _logger = logger;
    }

    [HttpGet()]
    public async Task<IActionResult> Get()
    {
        var someEntity = new SampleEntity();
        _logger.LogDebug("My DEBUG Log Message", someEntity, "Tag01", "Tag02");
        return Ok();
    }
}

Exemplos

Fornecemos uma aplicação simples de exemplo, verifique a pasta /src/sample deste repositório.

Sobrecargas disponíveis.

Debug

_logger.LogDebug("My DEBUG Log Message");
_logger.LogDebug("My DEBUG Log Message", "Tag01", "Tag02");
_logger.LogDebug("My DEBUG Log Message", someEntity, "Tag01", "Tag02");

Info

_logger.LogInformation("My INFO Log Message");
_logger.LogInformation("My INFO Log Message", "Tag01", "Tag02");
_logger.LogInformation("My INFO Log Message", someEntity, "Tag01", "Tag02");

Warning

_logger.LogWarning("My WARNING Log Message");
_logger.LogWarning("My WARNING Log Message", "Tag01", "Tag02");
_logger.LogWarning("My WARNING Log Message", someEntity, "Tag01", "Tag02");

Error

_logger.LogError("My ERROR Log Message");
_logger.LogError("My ERROR Log Message", "Tag01", "Tag02");
_logger.LogError("My ERROR Log Message", someEntity, "Tag01", "Tag02");

Fatal

_logger.LogFatal("My ERROR Log Message");
_logger.LogFatal("My ERROR Log Message", "Tag01", "Tag02");
