There are a number of possible reasons. Here are a few things to check:

  1. Have you invoked Puppet at least once on all your nodes? Puppet sets up MCO.
  2. Have you confirmed that there's no connectivity issues between your nodes and the ActiveMQ instance on your MCO masters?
  3. Check the logs on your managed nodes. Is the MCO agent running? Does it report any errors?
  4. How large is your install size? Beyond 1000 nodes, MCO needs some tuning.
  5. Have you tried increasing your timeouts, to give the nodes more time to respond?

Also, are the same nodes consistently missing, or do you see different results each time MCO runs?
