Azure功能未将自定义事件、依赖项记录到应用程序洞察

Question

我们在C中开发了Azure函数V3。我们尝试将一些自定义事件、依赖项等记录到Azure Application Insights。我们无法使用遥测客户端登录app insights。代码运行良好，没有任何错误。此外，可以查看从配置文件检索到的仪表键。但是，Ilogger日志可以在app insights traces表中找到。请查找我们使用的以下代码，

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

请确保您使用了以下正确的软件包：

微软蔚蓝色的WebJobs。登录中。ApplicationInsights，3.0版。18

和

更新软件包Microsoft。网Sdk。功能最新版本3.0。9

如果您在本地运行项目，请在local中添加APPINSIGHTS\u INSTRUMENTATIONKEY。设置。json，如下所示：

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

或者如果您在Azure门户上运行它，请使用Azure函数配置应用程序见解。

然后我测试了您的代码，自定义事件或依赖项被正确地记录到Application insights中。以下是截图：

如果您仍然有问题，请让我知道（也请提供更多细节）。
