Node.js - cluster.fork() - 如何檢查工作人員中的工作人員數量？

Question

使用cluster.fork時，有沒有辦法檢查創建的worker在工作人員本身內的編號？

if(cluster.isMaster) {
    console.log(`Master ${process.pid} is running`);    
    // Fork workers
    for (let i = 0; i < cores.length; i++) {
        cluster.fork();
    }
    cluster.on('exit', (worker, code, signal) => {
        console.log(`worker ${worker.process.pid} died`);
    });
}
else{   
    var number = CLUSTER_NUM; //Get the spawned number of the worker
}

Answer 1

cluster.worker.id應該是一個遞增的數字。

if (cluster.isWorker) {
  console.log(cluster.worker.id); // 0, 1, 2 etc.
}
