I get the following error when running the job via cron or manually. I know that the fxp0 is an Intel NIC but I have a realtek NIC using rl0. Any suggestions?
/usr/local/www/cgi-bin/rrdutil.cgi -a update
ERROR: couldn't find oid for fxp0!
Figured it out myself. Edit the /usr/local/etc/rrdutil.conf file and modify it with your NIC adapter.
