Monitoring of these additional JMX metrics can be useful: 

Topology

-        Current topology version

...

-        Method to count nodes grouped by some node attribute  

Communication SPI

-        Received messages count grouped by message type

...

-        Sent messages count grouped by receiver node 

Partitions allocation (for cache groups)

...

-        Maybe some methods to show partitions map/partition distribution statistics in the cluster

Jobs execution

-        Total jobs execution time (now job execution statistics gathered since node started and can't be used to calculate average execution time between probes, implementation of this metric can solve this problem)

Cache

-        Topology validation status for cache
