This is a feature request. Librenms has the MIB support feature where you can register a MIB with a device and librenmswill poll and graph the mib. This is known to create many useless graphs, and can clog both the librenms server and the devices.
So,I believe it would be useful to have an “Add OID” feature that will be applied on a specific device or device family (sysObjectId match) that will let us graph the particular OIDs that we need.
For starters, a statement in the config.php file, would do the job and avoid GUI work.
