如何使用 opentelemetry 將數據發送到 azure monitor（app insight）來部署服務？

Question

我有一個簡單的反應 nodejs 應用程序 ( http://23.100.37.60:3080/ ) 托管在 AKS 中，下面是我的 nodejs 后端服務器文件、我的部署清單 yml 文件和我的 docker 文件。 我按照此說明（ https://learn.microsoft.com/en-us/azure/azure-monitor/app/opentelemetry-enable?tabs=nodejs ）嘗試通過 opentelemetry 將數據發送到 app insight，但從未看到任何數據流入應用程序洞察力。 我想知道我是否配置不正確。 感謝您的幫助！

const tracerProviderConfig = {

const meterProviderConfig = {

const provider = new NodeTracerProvider(tracerProviderConfig);
diag.setLogger(new DiagConsoleLogger(), DiagLogLevel.ALL);

const meterProvider = new MeterProvider(meterProviderConfig);

// Create an exporter instance.
const exporter = new AzureMonitorTraceExporter({
  connectionString: "my connection string copied from app insight"
});

// Add the exporter to the provider.
provider.addSpanProcessor(new SimpleSpanProcessor(exporter));

provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));

provider.register();

registerInstrumentations({
  instrumentations: [new HttpInstrumentation()],
});

const tracer = trace.getTracer("example-basic-tracer-node-server");

app.use(bodyParser.json());
app.use(express.static(path.join(__dirname, '../my-app/build')));

app.get('/api/users', (req, res) => {
  console.log('api/users called!')
  res.json(users);
});

app.post('/api/user', (req, res) => {
  const span = tracer.startSpan("add-user-span");
  const user = req.body.user;
  console.log('Adding user:::::', user);
  users.push(user);
  span.addEvent('a user has been added', {
      'user': JSON.stringify(user)
  })
  span.end();
  res.json("user addedd");
});

app.get('/', (req,res) => {
  res.sendFile(path.join(__dirname, '../my-app/build/index.html'));
});

app.listen(port, () => {
    console.log(`Server listening on the port::${port}`);
});

您問題中的 docker 文件使用圖像節點：10，這兩個版本均不受支持：-

• 應用洞察，以及
• 開放遙測

查看以下文檔的先決條件部分以了解詳細信息 - 為 .NET、Node.js 和 Python 應用程序啟用 Azure Monitor OpenTelemetry

您可以嘗試使用 AppInsights 和 OpenTelemetry 都支持的較新節點圖像（v14、16 或 18）。

另外，請注意此預覽版的限制。 由於不支持“實時指標”，AppInsights 的數據攝取可能會延遲幾分鍾。 等待大約 5 分鍾，讓數據出現在 AppInsights 中。 您可以使用 applicationInsights 日志中的union *查詢來檢查幾分鍾后是否有任何數據到達 AppInsights 工作區。
