2. 后端設置

In Java, .NetCore, Node.js, Istio agents/probe, you should set the gRPC service address to ip/host:11800, with ip/host where your backend is.

config/application.yml

    gRPCHost: ${SW_CORE_GRPC_HOST:127.0.0.1}
    gRPCPort: ${SW_CORE_GRPC_PORT:11800}

3. UI 設置

config/application.yml

    restHost: ${SW_CORE_REST_HOST:127.0.0.1}
    restPort: ${SW_CORE_REST_PORT:12800}

webapp/webapp.yml

server:
  port: 8080

collector:
  path: /graphql
  ribbon:
    ReadTimeout: 10000
    # Point to all backend's restHost:restPort, split by ,
    listOfServers: 127.0.0.1:12800

4. 安裝 nodejs agent

4.1 安裝 nodejs module

npm install skyapm-nodejs@latest --save

4.2 初始化

It’s important that the agent is started before you require any other modules in your Node.js application. and you should require and start the agent in your application’s main file.
重要：在您的Node.js應用程序中，需要任何其他模塊之前，啟動代理skyapm-nodejs。

require('skyapm-nodejs').start({
    // Service name is showed in sky-walking-ui. Suggestion: set an unique name for each service, one
    // service's nodes share the same code.
    // this value cannot be empty.
    serviceName: 'test',
    // Collector agent_gRPC/grpc service addresses.
    // default value: localhost:11800
    directServers: 'localhost:11800'
});
