This may sound like a silly question but what I am attempting to do is
enable Ping Only as a starting method of monitoring devices. Now, this
may be because I do not understand enough about how Zenoss works but it
appears to not be doing it on devices as of right now. But when I look
in Networks on the autodiscovered devices I see that there are devices
there that are being pinged and attempted on monitoring through SNMP but
I really am only interested in monitoring at the very basic level of
ping or some other TCP connectivity test ALL devices that I have in
/devices.

The thing is that I need to start here. I am more towards monitoring
Network Devices, not servers. So I want to start as a proof of concept
on the very basic use of Ping to test connectivity before I move onto
SNMP querying. Why? Because I will have to do a lot of Mib customization
since these are not Cisco devices.

Does that make sense? Does it monitor via ping all devices in /Devices,
or do you have to enable that?

You have the right version number ;-) Erik was referring to the  
*section* of the Admin Guide, though -- not the version number.

I may have misinterpreted what you are asking, but maybe this will  
clarify:

  * the portscan functionality is for "modeling" or "discovering"  
services running on your network, and shouldn't be run very  
frequently (e.g., only when your network changes)
  * Zenoss does not use portscan for host availability checking -- it  
uses zenping for that

Again, please forgive if I have misunderstood your question.
