DS220+ Resource Monitor stopped showing any values

[bispawel]

Hello everyone,
since yesterday evening, when I had a voltage drop at home the NAS turned off, the resource monitor stopped showing any values - it’s totally empty

Silence in logs and notifications. What can I do with this ?
thanks and best regards

I have the same problem with my DS1821+

Usually (back in the day) this was due to SNMP service. Try and stop it/restart it and see if that will solve the issue.

Already tried that by adding a SNMPv3.
Applied the settings, no change.
Removed the settings, no change.

IMll try with the older version maybe.

I get this error when trying to enable it.

It still looks like it gets enabled but something is not right. Rebooted after enabling. No changes. Disabled it and got the same error. I'm not sure where to look.

I also get this error when trying to enable or disable usage history.

The problem was a corrupted snmpd.0.conf file.

Deleting it and restarting the snmp server with the systemctl restart snmpd command should fix it.

Thanks for posting this solution!

For the benefit of future beginners that might land here, I ssh'd into the synology, then did a

$ sudo rm /var/lib/net-snmp/snmpd.0.conf (to delete that file, then)
$ sudo systemctl restart snmpd

Resource Monitor working again!

Confirmed this worked for me, just running the second command gave error:

"Job for snmpd.service failed. See "systemctl status snmpd.service" and "journalctl -xe" for details."

I also did a $ sudo cat /var/lib/net-snmp/snmpd.0.conf
Just to see what was in there.

After running the

$ sudo rm /var/lib/net-snmp/snmpd.0.conf #to remove
$ sudo systemctl restart snmpd #to restart

Worked and i'm left with a snmpd.conf #no snmpd.0.conf

Only thing i'm thinking is that I was playing with and changing my network configuration (Physical) and 10GBE via PCIE
not sure what caused this or why it would have snmpd and why othertimes have snmpd.0 but thanks for this

Not sure how I would have solved otherwise.
