SMART App doesn't work

[arabesc]

The problem

LibreNMS is installed on a FreeBSD 13.0-RELEASE-p4 system. The SMART App doesn't work on it.

hi @arabesc

is your case same as mine ?
#13917

[f0o]

if you use RRDCached, then disable it and it will work again.

Alternatively upgrade RRD* to a newer version (1.4.8 did not work but 1.7.x did work. I dont know which specific version introduces the LIST command)

You should test /etc/snmp/smart script as your FreeBSD snmpd user, ie sudo -u snmp /etc/snmp/smart' (if snmpd run as snmp user) not as root. On my side I had to extend smart /usr/bin/sudo /etc/snmp/smart` in /etc/snmp/snmpd.conf and in /etc/sudoers.d add a snmp-smart file with:

snmp ALL=(ALL) NOPASSWD: /etc/snmp/smart, /usr/bin/env smartctl
