try:

snmpwalk host public enterprises

by default snmpwalk 'walks' the MIB-2 tree - AFAIK a generic snmp
tree that all version 2 snmp implementations must support. The
enterprises tree is used for vendor specific stuff, eg the process
monitoring in UCD, etc..

(AFAIK)

it's used for views, it's a way of defining a label for a
source/community tuple and allows you to have different access rights
for the same community depending on who is asking.

man snmpd.conf

but the snmp security stuff is really convoluted stuff. If it seems
confusing leave access to just a read-only community and remove all
rw communities/views.

no idea.

try:

snmptable localhost public system.sysORTable

and it will make a bit more sense. sysORTable /seems/ to describe
what kinds of "things" are supported (MIBs?). Indeed anywhere you see
"xxxx.xxxTable.xxx...." in snmpwalk output, you can do:

snmptable host community xxxx.xxxTable

to view a much clearer table of the values. eg, try:

snmptable localhost public dskTable

or to view the process info stuff you configured:

snmptable localhost public enterprises.ucdavis.prTable

or just:

snmptable localhost public prTable

it's not, it's just that SNMP is a good idea (trees of numbered
attributes) that grew into a monster at the hands of, AFAICT, many
committees and vendor implementations.
