[Bug]: Older(?) APC devices getting incorrectly Tagged as APC-UPS due to Over-Generalised SNMP tagging. #21103
Description
Bug description
When attempting to add certain APC devices with an OID of around 1.3.6.1.4.1.318. it appears that no profile can be forced, and it attempts to pull "default" metrics for it.
On closer inspection, it appears that the file
And the file
Is using the OID start of 1.3.6.1.4.1.318.1.* which is simply too generalist - if you look at OIDBase you can see that It splits into 4, and if you look into the .1 that apc-ups.yaml uses, you can note that there's a large variety of products that are not ups related in there.
The Solution is simple -
- change the
apc-ups.yamlfile to use the OID1.3.6.1.4.1.318.1.1.1.*as its base. - Change the apc.yaml file to also account for the correct OIDS, instead of targeting every PowerNet MIB at once (so, for example, target both
1.3.6.1.4.1.318.1.1.1.*to account forapc-ups.yaml, and1.3.6.1.4.1.318.1.3.4.*to account forapc-pdu.yaml - (nice to have, down the line) Have the full PowerNet MIB profile configured within SNMPs default.
Expected behavior
Devices using the PowerNet MIB that are not already accounted for shouldn't be included within the existing SNMP profiles
Steps to reproduce
- Attempt to add a custom OID profile stemming from the APC/PowerNet MIB - for instance,
1.3.6.1.4.1.318.1.1.10.* - Watch as nothing happens and it pulls default tcp/udp configuration data.
- Pull hair out wondering why there's sign of what OIDs you were expecting
- Profit!
