Python wrapper around smartctl which is supposed to make it usable
Use all available SMART data to ascertain whether a disk is probably okay or not.
As customer available SMART attributes are basically unusable to predict failure, the script will schedule selftests in order to discover disk (hopefully) before they result in loss of data.
The -n parameter will trigger nagios compatible output.
The script can autodetect disks.
Sample output:
/dev/sda: Disk healthy /dev/sdb: Disk healthy /dev/sdc: Disk healthy /dev/sdd: Disk healthy /dev/sde: Disk healthy /dev/sdf: Disk healthy /dev/sdg: Disk healthy /dev/sdh: Disk healthy /dev/sdi: Disk healthy /dev/sdj: Disk healthy /dev/sdk: Disk healthy /dev/sdl: Disk healthy /dev/sdm: Disk healthy

Nagios compatible output:

Help output:
usage: smart_status.py [-h] (-a | -d DISKS | -b SMARTCTL) [-n] [-u {warning,critical}] [-w {unknown,critical}] [-i IGNORE [IGNORE ...]] [-s SCHEDULE] [-t THRESHOLD] [-v] [-x] [-c]
Hard drives use Self-Monitoring, Analysis and Reporting Technology (SMART) to export data about the health of a disk device. smart_status.py is a tool to parse this data and tries to detect pending or post disk failures and report on disk status. Unfortunately SMART failure prediction is rarely reliable. Reporting on actual disk failures however generally works.
optional arguments: -h, --help show this help message and exit -a, --autodetect, --all Autodetect disks and scan. -d DISKS, --disks DISKS Only handle specific disk device. -b SMARTCTL, --smartctl SMARTCTL Overide smartctl binary location if not in path. -i IGNORE [IGNORE ...], --ignore IGNORE [IGNORE ...] Ignore specific disk devices. Helpful when scanning for all disks. -s SCHEDULE, --schedule SCHEDULE Frequency in days after which a selftest is considered out of date and will be rescheduled. -t THRESHOLD, --threshold THRESHOLD Frequency in days after which a selftest is considered out of date and will be warned about but not rescheduled. -v, --verbose Print more status information. -x, --strict Strict checking. Report a device not supporting SMART attributes or selftest as unknown/error instead of relying on the unreliable general SMART health feedback. -c, --color, --colour Colorize output.
Nagios: Format output to be usable as a Nagios compatible plugin.
-n, --nagios Return data in a form usable as a nagios check. -u {warning,critical}, --unknown {warning,critical} Change alert level of unknown smart status. -w {unknown,critical}, --warning {unknown,critical} Change alert level of warning smart status.
