Well, you should NOT change the DS's own inputs.conf, but rather create a few applications - each containing an inputs.conf file.
On the DS, create an 'app' under $SPLUNK_HOME/etc/deployment-apps/ for each type of server.
Such an app could contain an inputs.conf file specifying [monitor] stanzas relevant for that type of server.
Then you create/edit the serverclass.conf (typically under $SPLUNK_HOME/etc/system/local/) on the DS, defining which servers should have what app.
Then you make sure that the forwarders know whom to contact for configuration information, i.e. run ./splunk set deploy-poll <ip:port> on each forwarder. (replace ip:port with your DS ip and port (8089 by default)).
Then you can run ./splunk reload deploy-server on your DS.
If everything went well, your forwarders should contact the DS, download the new app, and start sending the logs.

hope this helps,
