How Do I Get OpenNMS to Collect Data from All SNMP Interfaces?
OpenNMS has the concept of primary and secondary SNMP interfaces. These interfaces must by definition have an IP address. By default the interface with the lowest IP address is designated as primary, and becomes the interface on which all SNMP data collection is performed for the node. By default, performance data is collected only for primary and secondary SNMP interfaces. You can choose other interfaces (particularly non-IP ones) whose data should be collected from the web UI by selecting “Configure SNMP data collection per interface”. If you would like to collect data on all of the interfaces on the node, you need to make a change to the /opt/OpenNMS/etc/datacollection-config.
