无法在Azure函数上使用Serilog.sinks.datadog.logs版本0.5.4查看DataDog日志 我正在学习Azure函数应用程序。我的功能应用程序是将日志写入DataDog的计时器触发器。我面临的问题与版本不兼容有关。 以下作品（我可以在

Question

，但是，我想使用最新的软件包，以下内容不起作用：

<PackageReference Include="Serilog" Version="4.2.0" />
<PackageReference Include="Serilog.Sinks.Datadog.Logs" Version="0.5.4" />

Serilog.sinks.datadog.logs版本0.5.4应与Serilog> = 2.9.0兼容，而Serilog.Sinks.sinks.periodicbatching是安装正确版本的传递依赖性。

i可以使用较低版本的

Serilog

（> = 2.9.0，Serilog.Sinks.Datadog.Logs0.5.4，反之亦然。 有人可以告诉我应该是我的下一步吗？

Create

.net9.0隔离的Azure函数

使用<4.2.0) to find the right fit for

Serilog.Sinks.Datadog.Logs

版本

0.5.4

Answer 1

Serilog

版本4.2.0.

。

I与.NET 9.0隔离的Azure函数进行了测试，并且可以按预期工作。

public static class Function1
{
    [Function("MyFunction")]
    public static void Run(
        [TimerTrigger("0 */2 * * * *")] FunctionContext context)
    {
        // Serilog logs
        Log.Information("C# Timer trigger function executed at: {time}", DateTime.Now);
        Log.Information("Time in UTC: {time}", DateTime.UtcNow);
        Log.Information("This is Datadog LOG");

        // ILogger logs
        var logger = context.GetLogger("Function1");
        logger.LogInformation("This is an Azure Functions log message.");
        logger.LogWarning("This is a Warning message");
        logger.LogError("this is a error message");

    }
}

PROGRAM.CS：

var host = new HostBuilder()
    .ConfigureFunctionsWebApplication()
    .ConfigureServices(services =>
    {
        Log.Logger = new LoggerConfiguration()
            .WriteTo.DatadogLogs(apiKey: "<DataDog_APIKey>")
            .CreateLogger();
    })
    .Build();

host.Run();

 -host.json：

{
    "version": "2.0",
    "logging": {
        "applicationInsights": {
            "samplingSettings": {
                "isEnabled": true,
                "excludedTypes": "Request"
            },
            "enableLiveMetricsFilters": true
        }
    }
}

Console输出：

Functions:

        MyFunction: timerTrigger
