Apologies for the late reply, but I've only just recently started
using the --rate feature myself (and it's an excellently useful
feature by the way so full kudos to Ton Voon and anyone else involved
in making that happen).

The check_snmp plugin will (on my system anyway), store the temporary
files under /usr/local/nagios/var/check_snmp/ .  If that directory
doesn't exist, it will create it - on my system it did so with
drwx------ permissions.

It's usually best to test plugins logged in as 'nagios' to avoid this
sort of problem, but to be honest I don't always bother and end up
hunting down the temporary files too!
