Well, what I mean is there are all sorts of obscurity builtin that I 
don't understand (and haven't found clear simple documetation):  MIBs, 
Community, security, etc.  I'd love to have a SNMP HOWTO for Linux.   
Installing snmp may not be hard, but USING it is another example.

Say, for example, I want to check disk usage.  I know how to do that 
using std plugins, or even if I had to write my own.  But how does one 
do that using SNMP? I don't even know to identify what to ask for.  How 
do I securely set it up so that only I can get the information necessary 
even on a publicly accessible host?
