Dual port network cards 🔗 link

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.
