23. Reallocation Event Count

24. Current Pending Sector Count

25. Offline Uncorrectable Sector Count

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"

You may need to create the smartd directory before smartd will write to it:

mkdir -p /var/log/smartd

Otherwise, all the smartd .csv files may get written to /var/lib/smartmontools (default location). See also https://linux.die.net/man/8/smartd for more info on the -A --attributelog=PREFIX command.

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.
