[smartmontools-support] new "temperature changed" messages

[martin f k. <ma...@ma...>]

I am very happy to see smartd/CVS now logging temperature changes in
a way that's a lot easier to parse.

While generating the new logcheck rules, I ended up wondering when
an exclamation mark is used.

Basically there are two types of messages: those identifying change:

  Temperature changed +1 Celsius to 46 Celsius (Min/Max 44/58)
  Temperature changed -3 Celsius to 41 Celsius (Min/Max 41!/58)
  Temperature changed +2 Celsius to 34 Celsius (Min/Max 34/34!)

and those reporting limits reached:

  Temperature 58 Celsius reached limit of 55 Celsius (Min/Max 58/58!)=20
  Temperature 56 Celsius reached limit of 55 Celsius (Min/Max 56/56)
  Temperature 61 Celsius reached critical limit of 60 Celsius (Min/Max 61/6=
1)
  Temperature 56 Celsius reached limit of 55 Celsius (Min/Max 56!/58)

Writing the logcheck rules, I want to be 100% sure about what I am
doing, and it's not entirely clear to me yet.

What do the exclamation marks mean?

Is there anything else I should know? Maybe you can suggest what
kind of messages I

  - can/should filter out completely
  - should elevate to a security warning

Thanks,
