A new version of check_smart, a monitoring plugin to monitor physical hard drives, solid state drives and NVMe drives, is now available. Version 6.14.1 contains several bugfixes and is therefore a pure bugfix release.

Fix SSD Lifetime Check when using warning thresholds

The first bug concerns the SSD Lifetime check, which can be launched using the parameter -l or --ssd-lifetime. When this was used in combination with a warning threshold list (using -w or --warn), the threshold for the Percent_Lifetime_Remain ATA attribute was always reset to the default warning value (90).

Pull request #93 from Yannick Martin solves this issue and the threshold can now be correctly overwritten using -w / --warn. Thanks for submitting the issue and the PR!

$ sudo ./check_smart.pl --skip-load-cycles -l -i auto -g '/dev/{sdb,sda}' -w Percent_Lifetime_Remain=85
OK: [/dev/sdb] - Device is clean [/dev/sdb] - Percent_Lifetime_Remain is non-zero (2) (but less than threshold 85) --- [/dev/sda] - Device is clean [/dev/sda] - Percent_Lifetime_Remain is non-zero (2) (but less than threshold 85)|

Fix debug output for raw attribute list

The "Raw Attribute List" tells check_smart.pl which ATA attributes to parse. The default list (see check_smart documentation for the current default value) can be overwritten using the -r / --raw parameter. In combination with --debug, the current raw attribute list can be seen in the debug output.

However this did not work for special parameters, such as -l / --ssd-lifetime. This dynamically adds the Percent_Lifetime_Remain attribute to the list - but it is not shown in the debug output. Pull request #94 fixes this.

Fix --hide-serial in debug output

The parameter --hide-serial can be used to hide the drive's serial number in the plugin output. However it was missed that the debug output (using --debug) can still show the serial number in the debug output. This was fixed in pull request #94 by using the command smartctl -q noserial in the background when check_smart.pl was launched with --hide-serial.
