How to integrate Node APM with Node.js cluster?

For PM2 Cluster mode, you dont need this setup. You can just follow normal installation steps.

All you have to do is, to install the atatus-node from npm, and then add require(‘atatus-node’) statement in the first line of your server code(NOT in your cluster code). Please refer our example:

// index.js
var cluster = require('cluster');

if (cluster.isMaster) {
    // Count the machine's CPUs
    var cpuCount = require('os').cpus().length;

    // Create a worker for each CPU
    for (var i = 0; i < cpuCount; i += 1) {
        cluster.fork();
    }

    // Listen for dying workers
    cluster.on('exit', function () {
        cluster.fork();
    });
} else {
    require('./server');
}

// server.js
// This should be the first line of your server.js
var atatus = require("atatus-nodejs");
atatus.start({
    licenseKey: "YOUR_LICENSE_KEY",
    notifyHost: "YOUR_ON_PREMISE_URL",
    appName: "YOUR_APP_NAME"
});

// Your Backend CODE
