Redhat disk free NULL2

RAM, traffic, Processor, ... is monitored with SNMP with success. But senssor "SNMP Disk free" is not working.

If I use SNMP V1 the error message is "NULL2", if V2 error message is:

"#N SNMP_EXCEPTION_NOSUCHINSTANCE223"

It is probably somehting missing in my snmpd.conf like in this thread: Can't use SNMP Linux disk free

Would you help me to know what is the missing line? I tried to add "includeAllDisks 10%".

Hi Yann,

SNMPd was reloaded after the configuration changes? This one might also be interesting:

Hi,

I think I had restarted the daemon, I suppose this action reload the config as well? It works fine now with V1 and V2 and with the extra line: includeAllDisks 10%.

Thank you.
