uHDD.health[*] doesn't detect failure with zabbix 3.4

[sabelka]

When smartctl -H detects a drive failure it returns an error code greater 0. (see man smartctl section RETURN VALUES). The zabbix-agent treats this case as command failure and returns ZBX_NOTSUPPORTED to the server.

Possible fix: changing the UserParameter configuration to return a zero error code in all circumstances, e.g. with

UserParameter=uHDD.health[*],sudo smartctl -H $1 || true

instead of

UserParameter=uHDD.health[*],sudo smartctl -H $1

Thanks! Can you share a STDOUT output of failed test?

[sabelka]

Sure! Here you go:

smartctl -H /dev/sdc
