Azure Application Insights with Node.js -监视用户统计信息

我按照文档（https://learn.microsoft.com/en-us/azure/azure-monitor/app/nodejs）将我的Node.js应用程序连接到Azure Application Insights，只使用了几行基本代码：

let appInsights = require("applicationinsights");
appInsights.setup(process.env.APPLICATIONINSIGHTS_CONNECTION_STRING).start();

在此之后，请求，响应时间等被很好地收集，但我想有关于用户的信息（用户数量，他们的设备类型等）。我没有找到任何基本的例子如何做到这一点。任何参考一个简单的例子？

已创建NodeJS应用程序并添加了与app.js中的应用程序洞察相关的代码。

我的app.js文件：

let  appInsights = require("applicationinsights");
appInsights.setup("Copy the Connection String from Application Insights Instance").start(); 

var  createError = require('http-errors');
var  express = require('express');
var  path = require('path');
var  cookieParser = require('cookie-parser');
var  logger = require('morgan');
var  indexRouter = require('./routes/index');

var  usersRouter = require('./routes/users');
var  app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended:  false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', indexRouter);
app.use('/users', usersRouter);
app.use(function(req, res, next) {
next(createError(404));
});
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {}; 
res.status(err.status || 500);
res.render('error');
});  
module.exports = app;

我的本地文件夹结构：

如MSDoc中所述，在views文件夹下的index.ejs中添加了Javascript函数。

我的index.ejs文件：
