Personally, I use SNMP for read-only network gathering information.

Depending on the device you are trying to poll, you can generally
retrieve almost all information from a device.

What you have described that you have already seems like SNMP. Can you
give an example of a device that you want to 'test' against?

Assuming that you have an SNMP v2 device available for polling, try this
on your FreeBSD box:

# pkg_add -r net-snmp
# rehash
# snmpwalk -v2c -c your_ro_community ip_or_name_of_device

If you want specifics to test against, let me know off-list, and I'll
give you a Cisco router to poll.
