Creating a Custom Module based on OIDs?

You may want to look for the "Anatomy of a DataSource: SNMP" video on the LM Academy. If I remember correctly it does cover the process of creating custom SNMP-based DataSources. It likely uses the old Interface though, so it may look a bit different in the actual portal.

You can also look at just about any Datasource that uses the SNMP collection method, like for example "snmpTCPUDP". Some of them use a Script collection method which you can also try but unless you know groovy scripting, I would stick with SNMP collection as it's a bit easier and based on the info above, I don't think you need to get fancy with scripts.

Note that you will only need to use the OID numbers and not the MIB "BM-MQ-APPLIANCE-STATUS" stuff.
