Defines logging severity levels.
Logs that contain the most detailed messages. These messages may contain sensitive application data.
These messages are disabled by default and should never be enabled in a production environment.
Logs that are used for interactive investigation during development. These logs should primarily contain
information useful for debugging and have no long-term value.
Logs that track the general flow of the application. These logs should have long-term value.
Logs that highlight an abnormal or unexpected event in the application flow, but do not otherwise cause the
application execution to stop.
Logs that highlight when the current flow of execution is stopped due to a failure. These should indicate a
failure in the current activity, not an application-wide failure.
Logs that describe an unrecoverable application or system crash, or a catastrophic failure that requires
immediate attention.
