+### 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.
