It seems likely that this device is failing to respond to these OIDs using GET, but they worked using WALK (as used during discovery, and I assume OidView).

You should verify you can snmpget these OIDs before going any further.

You can get the exact commandline we use to query them by doing ./poller.php -h <host> -m sensors -d

Subject: [Observium] APC ATS - Output/Input voltage

Hello,

I have a problem with Rack-mount Transfer Switches from APC

Observium shows zero voltage but OidView returns the correct values, what is wrong ?

Best regards,
