We have developed an IoT type device that includes an SNMPv3 agent. We are able to query the device and get all of the data using snmpwalk and also with PRTG. One of the requirements is that the data can be collected using OpenNMS but we can’t get that to work.
At the moment we are struggling to understand whether this is an issue with the SNMP agent in the device or whether we have something misconfigured in OpenNMS.
We have OpenNMS Horizon v26.1.0 installed on a Debian box. I have imported the MIB file that goes with the device and a file has been created as <opennms_install_dir>/etc/datacollection/Device-MIB.xml.
In the OpenNMS UI I have a node which shows HTTPS, ICMP and SNMP in the availability graphs which is correct - these are the three enabled protocols. If I look at the SNMP Interfaces under “Node Interfaces” it states “There are no SNMP interfaces for this node”.
How do I link this node to the imported MIB file?
