hw-check

Hardware health check and alerting.

• Check that edac-util drivers are loaded.
• Check that edac-util reports no errors.
• Check syslog for recent Hardware errors.
• Check sensors for any alarms (fan/temp/voltage). To do: Also monitor for anomalies.

For disk drive hardware checking and alerting see smartmontools.

Depends upon:

• edac-util for hardware error reporting.
• an appropriate edac driver module being loaded (e.g. amd64_edac_mod).
• lm-sensors for hardware sensor monitoring.
• the host being set up to send emails; one possibility is to use bsd-mailx and ssmtp, but several alternatives exist.
