I am trying to monitor free disk space for our Synology NAS through PRTG. I have downloaded and imported the MIBs, but do not see anything related to disk space in any of the MIBs. Instead, I just see things like temperature and uptime. Is there something I am looking in the MIBs to be able to monitor free disk space? I tried using PRTG's SNMP disk free sensor and the Synology physical disk sensor (as well as logical, just to test), but the SNMP one was not reporting accurate numbers and the Synology PRTG ones didn't help either.

I have tried both SNMPv3 and SNMPv2 to see if more accurate numbers would be shown. No difference was made between the two. Has anyone gotten their's to work? If so, how were you able to get it to work?

Hello there,

Simply use the SNMP Disk Free Sensor, see also here.

Kind regards,

Hello techstation,

In this case I would recommend to send us an email (support@paessler.com) with screenshots from the disk free sensor (tabs "Overview" and "Settings") and from the Synology's user interface or whatever else that shows that the numbers don't match.

Thank you & kind regards,

Erhard
