I assume you created a new template for this device? I can help more if you 
post the template (more appropriate for the devmon list though). Also, what OS 
does it run ? Windows server ?

(while we have Cisco call managers in the company, I don't monitor or have any 
access to them, but I've been meaning to work on templates for Windows servers 
for devmon, and that I can test myself)

Also, I would prefer to let everyone benefit from investments users make in 
creating templates, so once it is working, please consider sending it to me to 
include (or, file a bug on the devmon SF tracker) and attach the templates to 
that.

Most of the current cisco templates shipped with devmon should result in a 
working CPU graph, I have them for cisco-6509, cisco-7207, cisco-asa etc.

E.g.: 
http://devmon.svn.sourceforge.net/viewvc/devmon/trunk/templates/cisco-6509/cpu/message?revision=28&view=markup

The linux-openwrt template works nicely (the formatting isn't quite the same 
as sent by the hobbit client, but graphing works fine) for me on disks on 
linux (on WRT54GL, and normal linux host) monitored via snmp:


http://devmon.svn.sourceforge.net/viewvc/devmon/trunk/templates/linux-
openwrt/disk/message?revision=38&view=markup

(the "plain" option for TABLE allows one to try and get something closer to 
what the Hobbit rrd modules expect).

If you can't come right with the examples above, it would help to see some of 
the data you get via SNMP, and your existing template (at least the 'message' 
files).

Note, these are the two devmon tests that can create graphs without the devmon 
collector for Hobbit.
