javascript - Node.js - cluster.fork() - 如何检查工作人员中的工作人员数量？

Question

使用时cluster.fork，有没有办法检查worker创建的数字在工人本身内？

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
}

cluster.worker.id应该是一个递增的数字。

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