prerequisite

smartd must be running with -A option to write smartd attribute information to files.

For this you need to set smartd_opts (or SMARTD_ARGS, check smartd.service content) in /etc/default/smartmontools:

# dump smartd attrs info every 600 seconds
smartd_opts="-A /var/log/smartd/ -i 600"

smartd appends logs at every run. It’s strongly recommended to use logrotate for smartd files.

configuration

local:
  log_path : '/var/log/smartd/'

If no configuration is given, module will attempt to read log files in /var/log/smartd/ directory.
