I've implemented a work-around that works for me, by using the following line in xymonclient-freebsd.sh:</div><div><br></div><div>netstat -ibn|egrep "<Link|Name"| grep -v ^lo | while read A B C D E F G; do [ $A = "Name" ] || { C=<a href="http://0.0.0.0/0">0.0.0.0/0</a>; D=0.0.0.0; }; printf "%-5s %5s %-13s %-17s %12s %6s %14s %14s %6s %14s %6s\n" $A $B $C $D $E $F $G; done<br>
</div><div><br></div><div>The output now only includes interface lines with "<Link" that are not loopback devices (thus ignoring all the non-physical entries), and the "<Link#1>" and MAC address lines have been replaced with dummy values that parse correctly on the server. I now have useful interface graphs for my FreeBSD systems.</div>
<div><br></div><div>This is an ugly hack, and I only want this in place until a proper solution can be implemented.</div><div><br></div><div>So, I'm proposing that the xymonclient-freebsd.sh script be modified to use this line for [ifstat]:</div>
<div><br></div><div> netstat -ibn | egrep "<Link|Name"|grep -v ^lo</div><div><br></div><div>(This could leave the loopback addresses in place, and I don't think anyone would mind.)</div><div><br></div><div>
