Detect Netbackup agents installed on NBU master server

Is there is any way to figure out which all agents are installed on NBU master server ?

Please can someone list the available agents in NBU 7.5.

Is the list of installed agents in stored in registry or some file?

Below link list all the client and agents available with NBU 7.5, but I am little bit confused about which all are agents and not client.

Please correct if I am wrong.
