A large number of our systems have dual port network cards and I'm wondering if there is an easy way to monitor if a particular interface is down.
Each adapter has the following information in the client data,
General Statistics:
No mbuf Errors: 0 Adapter Reset Count: 1 Adapter Data Rate: 2000 Driver Flags: Up Broadcast Running Simplex 64BitSupport ChecksumOffload PrivateSegment LargeSend DataRateSet
I'm wondering if I could check the value highlighted and alert if it is not "up" without having to write an external script to do it?
I can't see anything in the analysis.cfg man page so I thought I'd ask here.
Thanks,

Not out of the box, you'll have to do some scripting yourself.
Since it's a large number of systems and you already have the data available in the client data, it seems an obvious candidate for a server-side module.
Take a look at the "xymond_rootlogin.pl script in the Xymon sources (you'll find it in the xymond directory). Adapting this to fit your needs should be a rather simple job for someone who is familiar with Perl programming (sad to say, I'm not).

I didn't test it and it has been quite some time, but I bonded two NICs for failover to the same switch. If one interface was down it put something in /var/log/messages. I monitored that entry.
Not saying this is a good, tested or even working approach, but that is what I did years ago.
