Linux::AtaSmart - XS wrapper around libatasmart
version 1.0.3
use v5.10.1; use Linux::AtaSmart; use Linux::AtaSmart::Constants qw/:all/; my $atasmart = Linux::AtaSmart->new('/dev/sda'); if (!$atasmart->smart_is_available) { die "Drive not SMART capable"; } say 'Disk size in bytes: ', $atasmart->get_size; say 'Awake: ' .

This is an XS wrapper around the Linux-only library, libatasmart. To read SMART info from a drive you will need to run as root, or have CAP_RAW_IO (which you will most likely have to set on your perl binary). HAVING GROUP WRITE PERMISSIONS IS NOT ENOUGH!
You may already have udisks installed, which you can query via Net::DBus.
On Debian-like systems, make sure you have libatasmart-dev installed.
libatasmart-dev
I have removed the sk_disk_ and sk_disk_smart_ prefixes for brevity.
sk_disk_
sk_disk_smart_
The SkDisk item is handled inside this module, you don't need to pass it to every method. You should create a new object to examine a different disk.
SkDisk
Results are returned directly by the methods, you don't have to pass references to be filled.
You don't have to manually call sk_disk_smart_read_data or sk_disk_smart_parse_data. This will be handled automatically by those methods that require it.
sk_disk_smart_read_data
sk_disk_smart_parse_data
All errors will throw exceptions via confess
confess
new(disk_device)
Creates a new Linux::AtaSmart object. Requires one argument, a string, identifying the disk to exmaine, e.g. /dev/sda, /dev/disk/by-label/HOME
Linux::AtaSmart
smart_is_available
Boolean.
smart_status
Boolean, true is GOOD, false is BAD.
check_sleep_mode
Boolean, true if awake, false if sleeping. Reading SMART data will wake up the disk, so check this first if you care.
dump
Prints all the available SMART info for the disk to STDOUT.
get_bad
Returns the number of bad sectors on the disk.
get_overall
Returns an integer corresponding to the overall status of the drive. See Linux::AtaSmart::Constants.
get_power_cycle
Returns number of times the disk has been power cycled.
get_power_on
Returns the total time this disk has been powered-on as a Time::Seconds object. The C library actually uses milliseconds, complain if you'd prefer that.
get_size
Returns the disk capacity in bytes.
get_temperature
Returns current disk temperature in celsius. The C library actually uses millikelvins, complain if you'd prefer that.
self_test(TEST_TYPE)
Starts a test of TEST_TYPE. See Linux::AtaSmart::Constants.
