I'd like feedback from the other developers and/or smartmontools users about some of the possible ways things that one might implement for printing raw values: (1) SIMPLE add -r ATT option, that would print the RAW values along with the normalized attribute values, if the NORMALIZED Attribute changes, for attribute ATT (2) SIMPLE add -P Report changes in 'Prefailure' raw values add -U Report changes in 'Usage' raw values add -B equivalent to -P -U (3) (SLIGHTLY) HARDER add equivalents of the -I and -i options to ignore some attributes, when reporting changes in the raw values It seems to me that in general there are not very many raw Attributes that one wants to track (perhaps temperature is the only one). This argues in favor of (1). On the other hand, (1) would not report all changes in temperature, just those that also make the Normalized Attribute value change... In favor of (2) is that it lets the user track all the raw Attribute values. But for many of these, it would be a nuisance. Eg, the power-on time will change every hour (or every minute or second for some disks!). So then it seems that we'd also need (3), which is a nuisance, not so much to code but because it bloats the data structures and also requires additional letters that can be used in /etc/smartd.conf -- we are practically running out of the alphabet. Sigh. Comments, anyone?? Bruce |
