#1606 new enhancement

SCSI Selftest Log does not print when JSON format requested

Keywords: json scsi Cc:

Description (last modified by Christian Franke)

Running the command 'smartctl -jl selftest /dev/sdX' works as expected when the device is ATA/SATA but does not output the selftest log data in the JSON when the device is SCSI/SAS.

* Demonstration of Problem *

comment:3 Changed 5 months ago by Marc

I don't know if I should create a new ticket or just leave this comment, but I discovered that there is similar behavior (missing data in the SCSI json output) for the 'smartctl -jl error' and 'smartctl -jA' outputs.

When outputting the error log normally, it contains a line "Non-medium error count: 0". When outputting in json format the non-medium error count is not present, and I would request that it be added.

When outputting the -A SMART information normally it outputs 7 lines in addition to the temperature:

Accumulated power on time, hours:minutes 6947:07
Manufactured in week 03 of year 2014
Specified cycle count over device lifetime:  50000
Accumulated start-stop cycles:  45
Specified load-unload count over device lifetime:  600000
Accumulated load-unload cycles:  2802
Elements in grown defect list: 0

When outputting -A in json mode you only get the grown defect count and the power on hours:mins. The other 5 data points are not included. I would request that at least the two 'Accumulated' values be added to the json output, the other 3 are not as important IMHO.
