如何在Application Insights数据中更改自定义属性名称

Question

是否可以为Application Insights中的现有页面视图数据更改自定义属性的名称？

Answer 1

您可以在页面查看事件离开浏览器之前用telemetry initializer更改页面查看事件的任何属性：

在您从门户网站获得的初始化代码段后立即添加此代码。

...
window.appInsights = appInsights;

// Add telemetry initializer
appInsights.queue.push(function () {
    appInsights.context.addTelemetryInitializer(function (envelope) {
        var telemetryItem = envelope.data.baseData;

        // To check the telemetry item’s type:
        if (envelope.name === Microsoft.ApplicationInsights.Telemetry.PageView.envelopeType) {
            // this statement removes url from all page view documents
            telemetryItem.url = "URL CENSORED";
        }

        // To set custom properties:
        telemetryItem.properties = telemetryItem.properties || {};
        telemetryItem.properties["globalProperty"] = "boo";

        // To set custom metrics:
        telemetryItem.measurements = telemetryItem.measurements || {};
        telemetryItem.measurements["globalMetric"] = 100;
    });
});
// end of insertion

appInsights.trackPageView();

此外，您可以在Google Analytics（分析）查询中的查询时间对列进行别名或复制：

pageViews | summarize sum(itemCount) by NameB=tostring(customDimensions.NameA) | ...

pageViews | extend NameB = customDimensions.NameA | ...
