如何将我的 pino 日志从 Nestjs 应用程序发送到 azure 中的应用程序洞察

Question

这是我的 pino 配置

import { config } from 'dotenv';
import { Params } from 'nestjs-pino';

config();


const pinoConfig: Params = {
  pinoHttp:
    {
      level: process.env.NODE_ENV !== 'production' ? 'debug' : 'info',
      formatters: {
        level: (label, number) => {
          return { level: label };
        },
      },
      customReceivedMessage: function(req, res) {
        return `request ${req.id} received: ${req.method} ${req.url}`;
      },
      customSuccessMessage: function(req, res) {
        return `${req.method} ${req.url} completed`;
      },
      customErrorMessage: function(req, res, err) {
        return `request ${req.id} to ${req.method} ${req.url} errored with status code: ${res.statusCode} message: ${err.message}}`;
      },
      
      transport: process.env.NODE_ENV !== 'production'
        ?
        {
          target: 'pino-pretty',
          options: {
            singleLine: true,
            ignore: 'pid,hostname,req.headers,req.remotePort,req.remoteAddress,req,res',

          }
        }
        : undefined
      ,
      
    }
};

export default pinoConfig;

在我的 main.ts 文件中

import { NestFactory, Reflector } from '@nestjs/core';
import { AppModule } from './app.module';
import { SwaggerModule } from '@nestjs/swagger';
import { Logger, LoggerErrorInterceptor } from 'nestjs-pino';


async function bootstrap() {
  const PORT = process.env.PORT || 3001;
  const HOST = process.env.HOST || 'localhost';
  const PROTOCOL = process.env.PROTOCOL || 'http';
  const app = await NestFactory.create(AppModule, { cors: true });
  app.useLogger(app.get(Logger));
  app.useGlobalInterceptors(new LoggerErrorInterceptor());

...
  await app.listen(PORT);
  const serverUrl = `${PROTOCOL}://${HOST}:${PORT}`;

...
}

bootstrap();

pino 日志在本地工作正常。但是，我还想将这些日志发送到 azure 中的应用程序洞察。我该怎么做呢？ 我已经创建了应用程序洞察资源，并且知道我的仪器和连接密钥。

通过使用

applicationinsights

npm 包 -

npm install applicationinsights

。

• 导入包并在

  main.ts

  文件中设置 Application Insights：

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { TelemetryClient } from 'applicationinsights';
import { setupInstrumentation } from 'applicationinsights/NestJs';

async function bootstrap() {
  const PORT = process.env.PORT || 3001;
  const HOST = process.env.HOST || 'localhost';
  const PROTOCOL = process.env.PROTOCOL || 'http';

  // Initialize Application Insights
  const instrumentationKey = 'YOUR_INSTRUMENTATION_KEY'; // Replace with your key
  const telemetryClient = new TelemetryClient(instrumentationKey);
  setupInstrumentation(telemetryClient);

  const app = await NestFactory.create(AppModule, { cors: true });

  // Start Application Insights telemetry
  telemetryClient.trackNodeHttpDependency();

  await app.listen(PORT);
  const serverUrl = `${PROTOCOL}://${HOST}:${PORT}`;

  console.log(`Application is running on: ${serverUrl}`);
}

bootstrap();

• 更新

  pinoConfig.ts

  文件以包含 Azure Application Insights 传输。

pinoConfig.ts：

import { config } from 'dotenv';
import { Params } from 'nestjs-pino';
import { TelemetryClient } from 'applicationinsights';

config();

// Initialize the Application Insights client
const appInsights = new TelemetryClient(process.env.APP_INSIGHTS_INSTRUMENTATION_KEY);

const pinoConfig: Params = {
  pinoHttp: {
    level: process.env.NODE_ENV !== 'production' ? 'debug' : 'info',
    formatters: {
      level: (label, number) => {
        return { level: label };
      },
    },
    customReceivedMessage: function (req, res) {
      return `request ${req.id} received: ${req.method} ${req.url}`;
    },
    customSuccessMessage: function (req, res) {
      return `${req.method} ${req.url} completed`;
    },
    customErrorMessage: function (req, res, err) {
      return `request ${req.id} to ${req.method} ${req.url} errored with status code: ${res.statusCode} message: ${err.message}}`;
    },
    transport: [
      {
        target: 'pino-pretty',
        options: {
          singleLine: true,
          ignore: 'pid,hostname,req.headers,req.remotePort,req.remoteAddress,req,res',
        },
      },
      // Add Azure Application Insights transport
      {
        target: 'pino-azure-appinsights',
        options: {
          client: appInsights,
        },
      },
    ],
  },
};

export default pinoConfig;

您可以在

portal>application insights>overview

中找到仪器密钥。

在应用程序洞察>调查>交易搜索中检查日志。
