I installed net-snmp agent (5.7.3) on my openBSD device, and provisioned
it to openNMS Horizon 19.0.1 for a test. There is not any private mibs
installed on the device.
After capturing all the SNMP traffic on the device, I found there are
many OIDs (almost 390 ) requested by openNMS. If we look at the default data
collection configuration file--datacollection-config.xml, we can find some
well-known vendors data group. In the captured SNMP traffic, I found the
following vendor data collection groups: bluecat, ericsson, zertico, zeus,
Dell, net-snmp(making sense).
My question is: all those vendors(bluecat, ericsson, zertico, zeus,
Dell) data groups are necessary? can someone give some hints?
