Error logs could be useful if.....

1) You expect errors to occur

2) You are connected to another system, buss, or communications channel that can hit you with unexpected operational sequences

3) You plan a means to read out the error counters and try to make sensical use of such data.

But at the same time please note that error counters and logging are not substitutes for a well though out system design, a carefully coded software application that is thourougly tested, and a fault recoverable power system strategy.
