+| DEBUG  | Logs that are used for interactive investigation during development. These logs should primarily contain information useful for debugging and have no long-term value.  |   |
+| INFO | Logs that track the general flow of the application.   |   |
+| WARNING | Logs that highlight an abnormal or unexpected event in the application flow, but do not otherwise cause the application execution to stop.  |   |
+| ERROR |  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. |   |
+| CRITICAL  | Logs that describe an unrecoverable application or system crash, or a catastrophic failure that requires immediate attention.  |   |
