我需要一个.NET 3.0工作服务来登录Azure Application Insights和EventLog。这些都不起作用(几乎(！

这是我的CreateHostBuilder:

public static IHostBuilder CreateHostBuilder(string[] args)
{
return Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
IConfiguration configuration = hostContext.Configuration;
WatchdogOptions options = configuration.GetSection("WorkerOptions").Get<WatchdogOptions>();
if (options == null) throw new WatchdogException("WorkerOptions settings are not set");
services.AddSingleton(options);
services.AddHostedService<Worker>()
// .AddApplicationInsightsTelemetryWorkerService();
;
})
.ConfigureLogging(logging =>
{
logging.ClearProviders();
//logging.AddConsole();
logging.AddApplicationInsights("<instr-key>");
logging.AddEventLog(new EventLogSettings
{
SourceName = "PNWatchdog",
LogName = "Watchdog"
});
});
}

1(无论我做什么事件日志都没有来自我的工作人员的任何记录。我确实在应用程序设置中设置了日志级别：

{
"Logging": {
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
}
},
"EventLog": {
"LogLevel": {
"Default": "Information",
"Microsoft.Hosting.Lifetime": "Information"
}
}
}

2(Application Insights只有在.AddApplicationInsightsTelemetryWorkerService()被注释掉时才获取记录并且检测密钥被硬编码在logging.AddApplicationInsights("8d3bc77d-1cc3-4c4a-83e4-6d8aaa87f8f7")中。应该怎么做才能从应用程序设置中获取密钥？

3(为什么这么麻烦

更新

这是完整的app.development.settings:

{
"Logging": {
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
},
"EventLog": {
"LogLevel": {
"Default": "Information",
"Microsoft.Hosting.Lifetime": "Information"
}
}
},
"ApplicationInsights": {
"InstrumentationKey": "8d3bc77d-1cc5-what-ever-0000000000"
}
}

更新2

ApplicationInsights添加到日志记录部分：

{
"Logging": {
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
},
"EventLog": {
"LogLevel": {
"Default": "Information",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"ApplicationInsights": {
"LogLevel": {
"Default": "Information"
}
} 
},
"ApplicationInsights": {
"InstrumentationKey": "8d3bc77d-1cc5-4c4a-83e4-6d8aaa87f8f7"
}
}

更新3

Logging:ApplicationInsights:LogLevel:的属性名称已更改

{
"Logging": {
"LogLevel": {
"Default": "Debug",
"System": "Information",
"Microsoft": "Information"
},
"EventLog": {
"LogLevel": {
"Default": "Information",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"ApplicationInsights": {
"LogLevel": {
"PushNotificationsWatchdog.Worker": "Information"
}
}
},
"ApplicationInsights": {
"InstrumentationKey": "8d3bc77d-1cc5-4c4a-83e4-6d8aaa87f8f7"
}
}

同样的事情-App Insights中没有记录。仪表键正确。

感谢@peter bons！

所以我更改了ConfigureServices()和ConfigureLogging()的顺序，并使用了UPDATE 2中的appsettings，现在它可以工作了！我们开始了：

public static IHostBuilder CreateHostBuilder(string[] args)
{
return Host.CreateDefaultBuilder(args)
.ConfigureLogging(logging =>
{
logging.ClearProviders();
logging.AddConsole();
logging.AddEventLog(new EventLogSettings
{
SourceName = "PNWatchdog",
LogName = "Watchdog"
});
})
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<Worker>()
.AddApplicationInsightsTelemetryWorkerService();
})
.UseWindowsService(); // windows only feature
}
