Ok, I think I see what is going on. Liebert uses an OBJECT-IDENTITY OID tree `lgpEnvTemperature` to label various metrics, rather than store them as strings in the target device.
This style of MIB identity lookup table is not supported by the snmp_exporter. No reason we don't support it, but it's not a commonly used technique. Most devices output their descriptions from the device as strings. Although, a quick search of some MIBs, it appears to be popular with UPS vendors. I suppose we should file a feature request issue for this. On Mon, Mar 18, 2024 at 1:07 AM Jonathan Davis <[email protected]> wrote: > Thank you for the assistance.
