You're getting stats for the physical interface. I don't think net-snmp lets you get stats for a single IP. One workaround would be a get-alias-stats script that pulls info from netstat for a particular IP: #! /bin/sh # usage: get-alias-stats <ip> ip=$1 netstat -ibn -f inet | while read line ; do set -- $line if [ "$4" = "$ip" ] ; then echo $7 echo ${10} uptime | sed -e "s/.*up \(.*\), .*user.*/\1/" hostname fi done Call that in mrtg, and pass it the alias IP you're interested in: Target[alias1]: `get-alias-stats 1.2.3.4` -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
