I've dabbled with monitoring our ONS 15454's, but the mibs are really poorly
written, and I'm not quite certain what data you can get from them. Since
it is sonet, you don't really get traffic stats, since it just transmits
idles if it has no other data.
The one thing I was really hoping to get from the box was alarms, but they
are completely broken until ONS version 4.0....
If you want to try monitoring the ports that are listed, just set a
reasonable maxbytes value and uncomment everything. But I imagine the
reason that ifSpeed is zero is that the ifInOctet counters don't increment
for any ports other than the ethernet blade.
You can dig into the transmission mibs, though, and on occassion find
something useful there about BERs.

Subject: [mrtg] Need some help
I am trying to use MRTG to monitor a Cisco ONS (Optical Network
Switch). This ONS is a carrier class switch used in
telecommunications. The ONS is sitting on an OC-48 sonnet ring and is
tied to an identical ONS at our remote location over an OC-3 overlay.
The OC-3 overlay is a 155Mb connection.
I downloaded the Cisco SONNET mibs from Cisco's website and used
cfgmaker to make a configfile with a statement to Load MIBs using the
LoadMIBs: /location/mibname.mib line file for this ONS box.
If I look at the config file, I get the following:
# Created by
# /usr/local/mrtg-2/bin/cfgmaker --global 'WorkDir:
/usr/local/www/ITWeb/MRTG' --global 'Options[_]: growright, bits'
--global 'Unscaled[_]: ymw' --global 'Refresh: 300' --global 'Interval:
5' --global 'WriteExpires: Yes' --global 'LoadMIBs:
/usr/local/mrtg-2/mibs/CISCO-SONET-CAPABILITY.mib,/usr/local/mrtg-2/
mibs/CISCO-SONET-EXT-CAPABILITY.mib,/usr/local/mrtg-2/mibs/CISCO-SONET-
MIB.mib' --dns-domain=coxnews.net --community=***** --show-op-down
--no-down fcpp-ons
### Global Config Options
# for UNIX
# WorkDir: /home/http/mrtg
# or for NT
# WorkDir: c:\mrtgdata
### Global Defaults
# to get bits instead of bytes and graphs growing to the right
# Options[_]: growright, bits

Unscaled[_]: ymw
Refresh: 300

I find it quite interesting that cfgmaker created a complete config
file for this ONS box, but commented out every line because "The
following interface is commented out because: * has a speed of which
makes no sense".
Any suggestions, or any one else using MRTG to monitor commercial grade
telco equipment?
Thank you,
