In the general case:
$ mco rpc puppet status:
is a single call after discovery, it does one thing and provides only
the one UI. `mco rpc` is a attempt to make a one-size-fits-all user
interface to ANY agent that complies to the RPC framework. In this goal
it succeeds in as much as you can call anything and see the results.
But it fails in that people who want to build tools ontop of mcollective
have their own uses and contexts.
So as a puppet user for example, you'd rather see:
dev1.devco.net: Currently idling; last completed run 23 minutes 10
seconds ago
dev4.devco.net: Currently idling; last completed run 19 minutes 38
seconds ago
dev2.devco.net: Currently idling; last completed run 9 minutes 51
seconds ago
than pages of this:
dev1.devco.net
Applying: false
Daemon Running: true
Lock Message:
Enabled: true
Idling: true
Last Run: 1489155759
message: Currently idling; last completed run 23 minutes 34
seconds ago
Since Last Run: 1414
Status: idling
`mco puppet status` produce the first output.
It's a way for people to write tools that either just show the results
in different ways or do higher order orchestrations like the 'mco puppet
runall' does.
There's no true answer to which is better/faster.
