[opennms-discuss] OpenNMS 1.1.0 and datacollection.xml

[Sean O'N. <se...@se...>]

Before I f' this file up, I want to understand how things work a bit 
more.  I've read over the FAQ entry 
http://faq.opennms.org/faq/fom-serve/cache/109.html and I have a somewhat 
understanding of how thing work.  I need to read it a couple more times and 
let it sink in.  But I have some questions already ...

I have a SS20 running Net-SNMP 5.0.6.  In the default datacollection.xml 
that comes with OpenNMS, the sysoidMask used for Net-SNMP is
.1.3.6.1.4.1.2021.250.  In the FAQ entry, this mask is commented out and 
the sysoidMask used it .1.3.6.1.4.1.2021.  Well the ...2021.250 doesn't 
exist within my OID tree on this SS20 - I think because I'm running 
Net-SNMP.  Is the .1.3.6.1.4.1.2021.250 a holdover for UCD-SNMP or something ?

I'm rather naive about SNMP at this level.  I do have UCD MIB information 
available but I'm confused why the ...2021.250 comes is there even though I 
know it won't work on my system.  I guess this explains why on my SS20 the 
only SNMP data being collection is Traffic Utilization, Bytes In/Out, 
Errors In/Out.  Its missing CPU, memory, and all that.

So if I wanted to collection CPU, memory, etc, would I basically update the 
sysoidMask and remove the .250 at the end in datacollection.xml ?

Just curious if I'm on the right track.
