FAQ
I have just upgraded my Cloudera Manager to version 4.6. I installed all
the monitor roles(activity, service, host, event, alert) on my secondary
named node.
A few questions:
-Which server is best to install the monitor roles on? Is the secondary
named node ok?
-I notice that by default, all it seems to monitor is the server that the
monitor roles are installed on. (All the charts are just for the secondary
named node only). How do I configure it to monitor all the nodes in the
cluster?

    Hi Jaykay,

    The location of the monitor roles depends on the size of the cluster.

    If your cluster is small, it probably doesn't matter. If it is big, or you
    plan to add a lot of nodes to it in the future, having the monitor roles on
    a separate node (or nodes) may be a good idea. This node (nodes) should
    also run the corresponding database so that each database / monitor role
    pair is co-located.

    By default, it monitors all the servers from all the roles. What version of
    CM did you upgrade from?
