核心应用程序日志记录请求，但不跟踪应用程序洞察

Question

我注意到我的 .net core 应用程序正在记录请求，但没有跟踪我的 azure 应用程序见解。

我正在我的 Startup.cs

中设置应用程序洞察

services.AddApplicationInsightsTelemetry(options =>
            {
                options.InstrumentationKey = Configuration["ApplicationInsightsInstrumentationKey"];
            });

我像这样在我的控制器中注入 ILogger

private readonly ILogger<HealthCheckController> _logger;

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

[HttpGet]
public IActionResult HealthCheck()
{
    // Custom EventId for logging
    var eventId = EventDefinition.TestMicroservice.HealthCheckController.HealthCheck;

    _logger.LogInformation(eventId, "Test Microservice health check successful.");

    return Ok("Test Microservice is running!");
}

我错过了什么吗？ 我多次点击控制器，并且看到请求被记录，但在跟踪下找不到我的自定义日志消息。

所以我发现，尽管我想使用 ILogger，但我仍然能够注入 TelemetryClient。 当我保留上面的代码时，我必须添加 .ConfigureLogging

        protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
        {
            return new ServiceInstanceListener[]
            {
                new ServiceInstanceListener(serviceContext =>
                    new KestrelCommunicationListener(serviceContext, "ServiceEndpoint", (url, listener) =>
                    {
                        ServiceEventSource.Current.ServiceMessage(serviceContext, $"Starting Kestrel on {url}");

                        return new WebHostBuilder()
                                    .UseKestrel()
                                    .ConfigureServices(
                                        services => services
                                            .AddSingleton<StatelessServiceContext>(serviceContext))
                                    .UseContentRoot(Directory.GetCurrentDirectory())
                                    .ConfigureAppConfiguration((context, config) =>
                                    {
                                        var configurationPackage = FabricRuntime.GetActivationContext()?.GetConfigurationPackageObject("Config");
                                        
                                        // Add Key Vault
                                        var kv = configurationPackage.Settings.Sections[KeyVaultOptions.Position].Parameters;                                        
                                        var credential = new ClientSecretCredential(kv["TenantId"].Value, kv["ClientId"].Value, kv["ClientSecret"].Value);
                                        var client = new SecretClient(new Uri(kv["Url"].Value), credential);

                                        config.AddAzureKeyVault(client, new AzureKeyVaultConfigurationOptions());
                                        config.Build();
                                    })
                                    .ConfigureLogging((context, logging) =>
                                    {
                                        logging.AddApplicationInsights(
                                            context.Configuration["ApplicationInsightsInstrumentationKey"]);
                                        logging.AddFilter<ApplicationInsightsLoggerProvider>("", LogLevel.Trace);
                                    })
                                    .UseStartup<Startup>()
                                    .UseServiceFabricIntegration(listener, ServiceFabricIntegrationOptions.None)
                                    .UseUrls(url)
                                    .Build();
                    }))
            };

默认情况下，ApplicationInsights 仅收集警告或更高级别的警告。您可以按照此处的文档进行更改：https://learn.microsoft.com/en-us/azure/azure-monitor/app/asp-net-core#how-do-i-customize-ilogger-logs-收藏

这对我有帮助：

.ConfigureLogging((context, logging) =>
                                {
                                    logging.AddApplicationInsights(
                                        context.Configuration["ApplicationInsightsInstrumentationKey"]);
                                    logging.AddFilter<ApplicationInsightsLoggerProvider>("", LogLevel.Information);
                                })
