Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) is an industry standard. S.M.A.R.T. performs disk monitoring and testing. It checks drive reliability and predicts hardware failures.

S.M.A.R.T. tests run on disks. Running tests can reduce drive performance. We recommend scheduling tests when the system is in a low-usage state. Avoid scheduling disk-intensive tests at the same time! For example, do not schedule S.M.A.R.T. tests on the same day as a disk scrub or resilver.

Name	Description
Check Interval	Enter the time in minutes for smartd to wake up and check if any tests are configured to run.
Power Mode	Select the power mode from the dropdown list. Options are Never, Sleep, Standby or Idle. S.M.A.R.T. only tests when the Power Mode is Never.
Difference	Enter a number of degrees in Celsius. S.M.A.R.T. reports if a drive temperature changes by N degrees Celsius since the last report.
Informational	Enter a threshold temperature in Celsius. S.M.A.R.T. sends a message with a LOG_INFO log level if the temperature is above the threshold.
Critical	Enter a threshold temperature in Celsius. S.M.A.R.T. sends a message with a LOG_CRIT log level and send an email if the temperature is above the threshold.
