Kadira not working correctly with meteorhacks:cluster multi-core setup

[hyperborea]

Ever since I've activated the cluster package using CLUSTER_WORKERS_COUNT the kadira dashboard appears to be missing data. Could it be that only the main node is sending metrics over?

Same Problem here.

@hyperborea I found a solution:

1. Don't use Auto Connect
2. Set different hostname for each cluster worker

Meteor.startup(function() {
  const { id, secret } = Meteor.settings.kadira;
  let hostname = 'your_hostname';

  // Check if cluster is active
  if (process.env['CLUSTER_WORKER_ID']) {
    // append number of cluster to the hostname
    hostname += `.${process.env['CLUSTER_WORKER_ID']}`;
  }

  Kadira.connect(id, secret, { hostname });
});

Every cluster worker counts as a session in Kadira. So with 4 cors you will see at least 5 sessions (cluster balancer + 4 workers).
