Let’s talk about how to use Nest.js to implement simple request monitoring in node

How to use Nest.js to implement request monitoring in node? The following article will introduce to you how to implement a simple version of request monitoring using the node framework Nest.js. I hope it will be helpful to you!

When we usually do business processing, we want to see the live business request at a time end and look at some interfacescpu Memory When making targeted interface optimization based on usage conditions, a monitoring system should be built. But if you are starting a small project yourself and don’t have so many resources, how should you implement it? Here we use a third-party package nest-status-monitor of Nest to take a look.

Post nodejsFramework--Nest.js Chinese documentation to facilitate further learning Nest Chinese documentation (https://docs.nestjs.cn/)

Installing dependencies

• First install the required dependencies in our Nest project

• yarn add nest-status-monitor Status monitoring package

• ##yarn add @nestjs/platform-socket.io 6.10.14 The socket package that needs to be used is because the status monitoring package version is incompatible with the latest socket package, so the old version

## is installed. #Implementation

State monitoring configuration

• /* statusMonitor.ts */
  
  export default {
    pageTitle: 'Nest.js Monitoring ',
    // 配置端口
    port: 3000,
    // 这里记得加全局路由 '/api'
    path: '/status',
    ignoreStartsWith: '/health/alive',
    spans: [
      {
        interval: 1, // Every second
        retention: 60, // Keep 60 datapoints in memory
      },
      {
        interval: 5, // Every 5 seconds
        retention: 60,
      },
      {
        interval: 15, // Every 15 seconds
        retention: 60,
      },
    ],
    chartVisibility: {
      cpu: true,
      mem: true,
      load: true,
      responseTime: true,
      rps: true,
      statusCodes: true,
    },
    healthChecks: [],
  };

  ##referenced in the mian.ts file and registered

  /* main.ts */
import { StatusMonitorModule } from 'nest-status-monitor';
import statusMonitorConfig from './config/statusMonitor';
async function bootstrap() {
 ...
 // 注册状态监控
  StatusMonitorModule.setUp(statusMonitorConfig),
}
bootstrap();

• Effect

Start the project

yarn run start:dev

• ##Enter

  http: in the browser //localhost:3000/api/status
This is the set display address. You can also set up

• according to your own needs. As shown in the picture above, I just tested and sent two

  400
The request and a
• 200

  request are clearly displayed at the bottom. Summary

So far we have built a small tool that can monitor server conditions in real time without high development costs.
