I encourage people to think a few moments about what to log and at what level.

You’re kind of telling a story to future potential trouble-shooters.

When you don’t think about it at all (it doesn’t take much), you tend to log too much and too little and at the wrong level.

But this article isn’t right either. Lower-level components typically don’t have the context to know whether a particular fault requires action or not. And since systems are complex, with many levels of abstractions and boxes things live in, actually not much is in a position to know this, even to a standard of “probably”.
