I couldn't use the somix templates with --if-template or --host-template

I used the same approach as above.

[ Incidently if you follow the examples at the site above it may be out of
date as far as CPU usage monitoring. Cisco seemed to change the MIB where
one could monitor the CPU usage after a particular revision of IOS 12.x.
There is a document on the cisco web site with the title "How to Collect CPU
Utilization on Cisco IOS Devices Using SNMP" that talks about it. So you may
want to check this out. I don't know if any of the other somix templates
would be out of date or need changes depending on the revision of OS. So
check vendors docs before using the OIDs suggested there. ]
