A new local system monitoring feature has been added, allowing to monitor numerous vital server metrics.

Most important metrics will be displayed when doing a pm2 ls:

┌─────┬─────────────────┬─────────────┬─────────┬─────────┬──────────┬────────┬──────┬───────────┬──────────┬──────────┬──────────┬──────────┐

// Or instanciate a custom PM2 instance

var pm2 = new PM2.custom({
  pm2_home :    // Default is the legacy $USER/.pm2. Now you can override this value
  cwd      :    // Move to CWD,
  daemon_mode : // Should the process stay attached to this application,
  independant : // Create new random instance available for current session
  secret_key  : // Keymetrics secret key
  public_key  : // Keymetrics public key
  machine_name: // Keymetrics instance name
});

// Start an app
pm2.start('myapp.js');

// Start an app with options
pm2.start({
  script   : 'api.js',
  instances: 4
}, function(err, processes) {
});

// Stop all apps
pm2.stop('all');

// Bus system to detect events
pm2.launchBus((err, bus) => {
  bus.on('log:out', (message) => {
    console.log(message);
  });

  bus.on('log:err', (message) => {
    console.log(message);
  });
});

// Connect to different keymetrics bucket
pm2.interact(opts, cb)

// PM2 auto closes connection if no processing is done but manually:

pm2.disconnect(cb) // Close connection with current pm2 instance
pm2.destroy(cb)    // Close and delete all pm2 related files of this session

• [#2071 #2075] Fix pm2-dev command

This release is about PM2's internals refactoring, homogenization in action commands (in terms of behavior and outputs). Some interesting features has been added, as YAML file support (for application declaration) and some syntaxic sugar. The Keymetrics interface has been enhanced, dividing by two the memory usage and avoiding any possible leak in any potential scenarios. Reconnection system has been refactored too, we kindly ask our Keymetrics users to upgrade to this version ASAP.

This version has been heavily tested in testing, production environments and deeply monitored in terms of CPU and Memory usage.
