Hi Uddipan,

In my Opinion
 Hadoop Jobtracker Interface provides every Details Including
   # number of Map slots
   # number of Reducer slots

 and other Infromation can also be found in Log files generated.
 Which can also be explored through the same Interface.
 Jobtracker address : Masternode:your_port/jobtracker.jsp <http://#>

Other useful details can also be found.
