Description

Currently in NameNode UI, the Summary part also includes information:

Security is off.
Safemode is off.
**** files and directories, ***** blocks = **** total filesystem object(s).
Heap Memory used **** GB of **** GB Heap Memory. Max Heap Memory is **** GB.
Non Heap Memory used **** MB of **** MB Commited Non Heap Memory. Max Non Heap Memory is ****.

We could add similar information for router, for better visibility.
