Hello Omkar,
You would have found the same in installation guides as well.
For your reference, you can find the same in below path.
Goto http://service.sap.com/swdc -> SAP Software Download Center -> Installation and Upgrades -> My Company's Application Components -> My Company's Software -> SAP Solution Manager -> Select your version -> SAP Solution Manager Diagnostics -> SMD Agent
Hope this helps.
Regards,
Denish
