typescript - Application Insights TrackEvent 从未在 Azure 中保留

Question

我正在尝试为 Node 实现 SDK 以跟踪我们代码库中的自定义事件。我编写的服务是从异步方法链中调用的，并在 Azure Functions 中运行：

public async handleEvent(event: Event) {
    // Do stuff

    // Then report event
    this.reportEvent(event);
}

private reportEvent(event: Event) {
    if (this._applicationInsightsService) {
        this._applicationInsightsService.reportEvent(event)
        this._context.log("Successfully sent event to application insights")
    } else {
        this._context.log("Could not send metrics to application insights, service is not defined")
    }
}

服务本身如下所示：

export class ApplicationInsightsService {

    private _instance: ApplicationInsights

    private constructor(connectionString: string) {
        this._instance = new ApplicationInsights({ 
            config: {
                connectionString: connectionString
            } 
        })
        this._instance.loadAppInsights()
    }

    public static create() {
        if (process.env.APPLICATION_INSIGHTS_CONNECTION_STRING === undefined) {
            throw new Error("APPLICATION_INSIGHTS_CONNECTION_STRING undefined, cannot report metrics")
        }
        return new ApplicationInsightsService(process.env.APPLICATION_INSIGHTS_CONNECTION_STRING)
    }

    public reportEvent(event: Event) {
        this._instance.trackEvent({
            name: event.type,
            properties: event
        })
        this._instance.flush()
    }
}

customEvents但是，当我查询表时，我发送的事件在 Azure 门户中永远不可见。我已经等了超过 10 分钟，因为我知道应用程序洞察可能会有延迟。

我尝试过调用异步刷新并await在调用它时使用，但这也无济于事：

Promise.resolve(this._instance.flush(true))

环境变量APPLICATION_INSIGHTS_CONNECTION_STRING的格式为InstrumentationKey=xxx;IngestionEndpoint=https://westeurope-1.in.applicationinsights.azure.com/.

我的问题似乎与C# Application Insight Failure: TrackEvent Does not send to Azure Application Insight非常相似，但我真的需要休眠/超时来考虑时间吗？

我运行它时的日志输出什么也没说，没有产生任何错误，也没有任何异常：

我错过了什么？

更新

所以显然有一个JavaScript 和一个Node SDK 让事情变得更加混乱。我将尝试使用 Node SDK，但我不明白为什么前者不应该工作。

解决方案

ApplicationInsightsService 的以下构造有效：

// Previously:
// import { ApplicationInsights } from "@microsoft/applicationinsights-web"
import { TelemetryClient } from "applicationinsights"

export class ApplicationInsightsService {

    private _instance: TelemetryClient

    private constructor(connectionString: string) {
        this._instance = new TelemetryClient(connectionString)
    }
}

对于节点应用程序：

做：npm install --save applicationinsights

不要：npm install --save @microsoft/applicationinsights-web

工程建设如下ApplicationInsightsService：

// Previously:
// import { ApplicationInsights } from "@microsoft/applicationinsights-web"
import { TelemetryClient } from "applicationinsights"

export class ApplicationInsightsService {

    private _instance: TelemetryClient

    private constructor(connectionString: string) {
        this._instance = new TelemetryClient(connectionString)
    }
}

对于节点应用程序：

做：npm install --save applicationinsights

不要：npm install --save @microsoft/applicationinsights-web
