Re: Node sysObjectID

Hi Trev,

   OpenNMS doesn't have any MIB data built-in for this OID, therefore it 
won't collect any data unless you install a MIB, which I presume you are 
doing? (I looked back at your email about the Liebert Aircon and you 
were talking about installing MIBs there - incidentally, YES - you do 
need to generate snmp graph properties templates as well - I'm not sure 
if that question got answered)...

So in order to handle your tape library you first need to take the 
Quantum MIB files and compile them using the MIB Compiler in the OpenNMS 
GUI.. You need to generate datacollection, graphs and events, and 
restart OpenNMS to be sure it's actually loaded them. The node in 
question also needs to have at least one primary SNMP interface.

Next, check your /etc/opennms/datacollection-config.xml file and make 
sure that there's an <include-collection> tag which includes the 
generated Quantum MIB data. Take note of the name attribute of the 
'snmp-collection' which includes your events.
Check your /etc/opennms/collectd-config.xml file - and locate the 
package which contains your SNMP collector with a parameter of 
'collection' which matches the name of you noted above, and then pay 
close attention to the 'filter' tag to be sure that it's not excluding 
your device for any reason.

Then have a look through the generated datacollection file in 
/etc/opennms/datacollection - be certain that there are OID definitions 
which match what you're seeing in snmpwalk.

Once this is all in place, aside from checking the graphs you can poke 
around in the /var/lib/opennms/rrd/<node_id>/ directory and see if it's 
actually collecting any data.

If it's still not working then I think you'll need to take a closer look 
at the debug log output from instrumentation and collectd.
