Excellent Question Allisson, as I have just been wondering the same thing.
Suresh, does the same thing apply to the other Plugins, such as
AppManager and CMDB ie installing them on the Central server will
allow anyone with access to Central to view data collected by all Plugins?
This would be my preferred configuration, subject to the
limitations you provided above, which would leave the Probes as device
discovery/data collector servers which does popultae into Central.
Cheers
