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 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 , and collects SMART data +at the frequency specified by the option . 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. + +OPTIONS +------- +-r :: +--run-tim=:: + (optional) Number of hours to log data (default = 20 hours) + +-f :: +--freq=:: + (optional) How often you want to log SMART data + (0.25 = 15' , 0.5 = 30' , 1 = 1 hour, 2 = 2 hours, etc.). Default = 10 hours. + +-o :: +--output-file=:: + (optional) Name of the log file (give it a name that easy for you to remember + what the test is). You can leave it blank too, the file name will be generated + as --.txt. + +-n :: +--test-name=:: + (optional) Name of the test you are doing. We use this string as part of the name of the log file. + + +EXAMPLES +-------- +* Temperature characterization: ++ +------------ +# nvme virtium save-smart-to-vtview-log /dev/yourDevice --run-time=100 --record-frequency=0.25 --test-name=burn-in-at-(-40) +------------ ++ + +* Endurance testing: ++ +------------ +# nvme virtium save-smart-to-vtview-log /dev/yourDevice --run-time=100 --record-frequency=1 --test-name=Endurance-test-JEDEG-219-workload +------------ ++ + +* Just logging: Default logging is run for 20 hours and log every 10 hours. ++ +------------ +# nvme virtium save-smart-to-vtview-log /dev/yourDevice +------------ + +NVME +---- +Part of the nvme-user suite -- cgit v1.2.3
