从本地service fabric将日志写入应用程序洞察

Question

我正在尝试将Azure App insights service集成到service fabric App中，用于日志记录和检测。我正在本地VM上运行fabric代码。我完全遵循了这里的文档[场景2]。docs.microsoft.com上的其他资源似乎也指明了相同的步骤。[例如：https://docs.microsoft.com/en-us/Azure/service-fabric/service-fabric-diagnostics-event-aggregation-eventflow出于某种原因，我在App Insights中看不到任何事件条目。执行此操作时，代码中没有错误：

ServiceEventSource.Current.ProcessedCountMetric("synced",sw.ElapsedMilliseconds, crc.DataTable.Rows.Count);

EventFlowConfig.json内容

    {
      "inputs": [
        {
          "type": "EventSource",
          "sources": [
            { "providerName": "Microsoft-ServiceFabric-Services" },
            { "providerName": "Microsoft-ServiceFabric-Actors" },        
            { "providerName": "mystatefulservice" }
          ]
        }
      ],
      "filters": [
        {
          "type": "drop",
          "include": "Level == Verbose"
        }
      ],
      "outputs": [
        {
          "type": "ApplicationInsights",
          // (replace the following value with your AI resource's instrumentation key)
          "instrumentationKey": "XXXXXXXXXXXXXXXXXXXXXX",
          "filters": [
            {
              "type": "metadata",
              "metadata": "metric",
              "include": "ProviderName == mystatefulservice && EventName == ProcessedCountMetric",
              "operationProperty": "operation",
              "elapsedMilliSecondsProperty": "elapsedMilliSeconds",
              "recordCountProperty": "recordCount"
            }
          ]
        }
      ],
      "schemaVersion": "2016-08-11"
    }

在ServiceEventSource.cs中

[Event(ProcessedCountMetricEventId, Level = EventLevel.Informational)]
    public void ProcessedCountMetric(string operation, long     elapsedMilliSeconds, int recordCount)
    {
        if (IsEnabled())
            WriteEvent(ProcessedCountMetricEventId, operation, elapsedMilliSeconds, recordCount);
    }

编辑从“Program.cs in fabric stateful service”添加诊断管道代码

using (var diagnosticsPipeline =
                ServiceFabricDiagnosticPipelineFactory.CreatePipeline($"{ServiceFabricGlobalConstants.AppName}-mystatefulservice-DiagnosticsPipeline")
            )
            {
                ServiceRuntime.RegisterServiceAsync("mystatefulserviceType",
                    context => new mystatefulservice(context)).GetAwaiter().GetResult();

                ServiceEventSource.Current.ServiceTypeRegistered(Process.GetCurrentProcess().Id,
                    typeof(mystatefulservice).Name);

                // Prevents this host process from terminating so services keep running.
                Thread.Sleep(Timeout.Infinite);
            }

事件源是一个棘手的技术，我已经使用它一段时间了，总是有问题。配置看起来不错，没有访问环境就很难调查，所以我会提出我的建议。

你必须注意以下几点：

如果您正在侦听来自其他进程的etw事件，则您的进程必须使用具有“性能日志用户”权限的用户运行。检查您的服务在哪个标识上运行，以及如果它是性能日志用户的一部分，则检查谁有权创建事件会话以侦听这些事件。
