Logs, in general, should never be seen by the user. I'm referring more to development and run-time logs. Things like the httpd log. Of course, we may be talking around each other due to semantic differences.

Sometimes, when I'm writing up logging capability, I'll have certain messages go to one log, which would be the error log. I'll also have more detailed information go to another log. Then, I can read a small log to find that a problem occurred. Using timestamps, I can find out where in the other log the error is, then find out what occurred.

*shrugs* Different folks, different strokes. Whatever works.

We are the carpenters and bricklayers of the Information Age.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
