Description:
ndb_mgm is not able to show node statistics and info.

How to repeat:
n/a

Suggested fix:
It would be good to be able to see these stats (and others) by issuing a command from the ndb_mgm client, while this information is available by directly querying ndb_mgmd that is not sufficient.

Possibly also make ndb_mgm query this information periodically and issue an alert if allocated memory is near exhaustion.

verified the first part, periodic polling should be a task performed by an external monitoring tool though, ndb_mgm should only be used to provide the needed data on request

Ok, how about making this tool do many other health related checks regularly? (I can't think of any at this point, though)
