I wrote a perl script to query the graphs over snmp, net-snmp allows
scripts to be run, and doesn't run it more often then every 30 seconds
even if you query it over and over.

$ snmpget NAMESERVER SNMP_COMMUNITY enterprises.ucdavis.extTable.extEntry.extOutput.2
enterprises.ucdavis.extTable.extEntry.extOutput.2 = 60146054 7198491
10306427 11192315 281 1878 13503 408 4877 88864234

See what the graphs look like at http://www.campin.net/DNS/ (bottom).

I've never documented it or released the code (I'd have to ask my
employer for permission), but if people would like me to see if I can do
it, I will check into it.

OBTW, there's huge problems with SNMP implementations right now, you
really need packet filter protection if you're using SNMP.
