Description
smartd has knowledge of the state of all the hard drives in the system, and as such it is a perfect abstraction layer between the hardware and services or software that would make use of such information.
Unfortunately, although it is a daemon, it currently behaves in a cron-like fashion, by querying the HDD at specified intervals and optionally sending emails when a fault is detected.
My proposal is to add a Unix socket interface to smartd so that the last-checked HDD state and drive inventory can be queried from external software. I am proposing a simple query interface: 1-line command, 1-line response.
What smartd should provide on the socket:
- a hello, I am running message; smartd version string included
- a command to shut down
- a command to reload the configs
- a command to provide internal daemon statistics, like daemon runtime, etc
For the drive data that should also be:
- a command to enumerate the drives monitored by smartd
- a command to provide SMART variables for the specified drive (including SCSI/ATA specifics)
Optionally, these might make sense too:
- a command to get/change device settings (-g -s in smartctl)
- a command to deal with self-tests, SMART-GPT logs

We would also use a simple socket client to print out the daemon state and data.
