For the MBean attributes, we show every cluster node in a
column and the values underneath. This causes the number
of columns to be really large for large clusters.
We need to provide a collapsed view, where there will
only be one column for attribute values.
If an attribute value differs for different nodes, we
will show a link,
which will take the user to another page, where the
be listed row-wise (one row for every node in the cluster).
This lets the number of nodes to grow, without affecting
the page layout. For a Read-Write attribute, the values can
be changed on this new page.
If the attribute value is the same across the cluster,
it will be
shown in the mbean view, and it can be changed for the
If some nodes in the cluster are down, then these nodes
should be listed in the top section of the page.
