Description
An informational message is something that was recorded for
audit purposes, usually a user action or a change of states that is
normal behavior.
A warning is not as severe as an error, but if possible, the
condition should be corrected before it becomes an error. It
might also be a condition that requires additional monitoring or
maintenance.
An error typically indicates a failure or critical condition that
impairs service or an expected function.
