[Devmon] MDS9000 fibre channel switch

[Peter W. <pet...@gm...>]

Hi all,

In the past I've discovered a few times that CRC errors on our fibre channel
switch caused us many harm. I installed devmon next to Xymon and I made a
status-check with the documentation. All is working well, for the status
check (online, location etc). So far so good.

Now I want some real stuff to be monitored. The 20 fibre channel ports on
the switch (CRC errors, underrun etc). I have access to this switch. I have
access to the MIB description (
http://www.cisco.com/en/US/docs/storage/san_switches/mds9000/sw/rel_2_x/fabricware/mibs/reference/guide/alliance.html)
but I am wondering...
If I would like to monitor all 20 ports, do I have to create 20 subdirs with
contents (oids, thresholds ) for each port? There mus be an easier approach,
but then again: I'm fairly new to devmon.

When I issue a snmpwalk-command, for example:

$ snmpwalk -v2c -c public ip.address.masked.here 1.3.6.1.3.94.4.5.1.40

It responds with 20 ports.

How can I sample it all up to one oids-file (for example in the
fc_error-directory) but have an table-like-output for each switchport.

Any help is very much appreciated.

Regards, Peter
