Cactid in portage
Recently, I got around to finally getting cactid into portage for those cacti lovers out there. Its a great alternative to the php based snmp poller with a significant improvement on speed. If you use cacti, please give cacti-cactid a try!
echo "net-anaylyzer/cacti-cactid ~x86" >> /etc/portage/package.keywords
emerge cacti-cactid
Let me know if you have any issues.
