Azure 功能未记录自定义事件、对应用洞察的依赖性

Question

我们在 C# 中开发了 Azure Function V3。我们尝试将一些 custom events, dependencies 等记录到 Azure Application Insights。我们无法使用 TelemetryClient 登录应用洞察。代码运行良好，没有任何错误。此外，可以看到从配置文件中检索到 instrumentation key。但是 Ilogger 日志可以在应用洞察跟踪 table 中找到。请在下面找到我们使用的代码，

public class CommunityCreate
    {
        private readonly TelemetryClient telemetryClient;
        public CommunityCreate(TelemetryConfiguration telemetryConfiguration)
        {
            this.telemetryClient = new TelemetryClient(telemetryConfiguration);
        }

        [FunctionName("Function1")]
        [return: ServiceBus("sample", Connection = "ServiceBusProducerConnection")]
        public async Task<string> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = "Account/{id:int?}")] HttpRequest req, string id, ILogger log)
        {
            //log.LogInformation("C# HTTP trigger function processed a request.");
            DateTime start = DateTime.UtcNow;

            string name = req.Query["name"];

            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = name ?? data?.name;

            var evt = new EventTelemetry("Function called");
            evt.Context.User.Id = name;
            this.telemetryClient.TrackEvent(evt);

            // Generate a custom metric, in this case let's use ContentLength.
            this.telemetryClient.GetMetric("contentLength").TrackValue(req.ContentLength);

            // Log a custom dependency in the dependencies table.
            var dependency = new DependencyTelemetry
            {
                Name = "GET api/planets/1/",
                Target = "swapi.co",
                Data = "https://swapi.co/api/planets/1/",
                Timestamp = start,
                Duration = DateTime.UtcNow - start,
                Success = true
            };
            dependency.Context.User.Id = name;
            this.telemetryClient.TrackDependency(dependency);


            telemetryClient.TrackEvent("Ack123 Recieved");
            telemetryClient.TrackMetric("Test Metric", DateTime.Now.Millisecond);


            return name;
        }
}

Answer 1

请确保您使用的是正确的软件包，如下所示：

Microsoft.Azure.WebJobs.Logging.ApplicationInsights, version 3.0.18

和

更新包Microsoft.NET.Sdk.Functions最新版本3.0.9.

如果您是运行本地项目，请在local.settings.json中添加APPINSIGHTS_INSTRUMENTATIONKEY，如下所示：

{
    "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "xxxx",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "APPINSIGHTS_INSTRUMENTATIONKEY": "xxx"
  }
}

或者，如果您运行它在 azure 门户上，请使用 azure 功能配置 Application insights。

然后我测试了您的代码，自定义事件或依赖项已正确登录到 Application insights 中。这是屏幕截图：

如果问题仍然存在，请告诉我（并提供更多详细信息）。
