Description of problem:
========================
I had a 4node cluster on Console with 3.1.3 build. Nagios (with mail notification) was also configured on the rhsc-mgmt node. While updating the gluster version from 3.1.3 to 3.2 of the hosts, it is advised to move them to maintenance on Console. After doing so, we would _not_ expect nagios to continue monitoring the hosts. But it does.

This results in receiving unnecessary and innumerable mail notifications stating the poor health of the many services corresponding to every volume and host and cluster. It is not alarming to the admin to receive such mails as one knows that the hosts are undergoing an update, but it is not something that one would have expected, certainly not the _number_ that one actually receives.

RameshN did mention that Console does not interact with Nagios, other than allowing it to display the graphs, and that the intended result can be achieved by explicitly scheduling a downtime (for a particular duration) in Nagios homepage. 

If we choose to live with it (no harm), then it should be documented advising users to do the needful if they choose to do so.
