From: Daniel Baumann This command automates the process of collecting SMART data periodically and
saving the data in a ready-to-analyze format. Each entry is saved
with timestamp and in csv format. Users can use excel to analyze the data.
-Some examples of use cases are collecting SMART data for temperature characterization,
-collecting data to calculate endurance, or collecting SMART data during a test
-or during normal operation.
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
On success, the command generates a log file, which contains an entry for identify device -(current features & settings) and periodic entries of SMART data.
This command runs for the time specified by the option <run-time>, and collects SMART data -at the frequency specified by the option <freq>. If the output file name is not specified, -this command will generate a file name that include model string and serial number of the device.
If the test-name option is specified, it will be recorded in the log file and be used as part -of the log file name.
