Hi all, I'm trying to work out the documents of 2 new GShell commands added in G2.2.

(1) Cluster/deploy
(2) Cluster/heartbeat

Cluster/deploy is quite easy to understand but I am confused about the usage of (2). What does the heartbeat mean here, a newly added farm node?  What's the scenario when a user want to use this command?

Could anyone shed more light on me, if you can provide a sample, that would be much appreciated.

Thanks in advance.
