Thanks for your job.

smartd tracks the other attributes as well. By default, changes of normalized attribute VALUE will appear as LOG_INFO in syslog.

To monitor changes of normalized and RAW values of attribute 232 as LOG_CRIT, try this in /etc/smartd.conf:

/dev/sda -a -r 232! -R 232!

Note that SMART attributes are not standardized at all. In practice, SSDs have much more vendor-specific differences than HDDs. There is no "one size fits all" solution for SSDs.
