The standard ranking of logging levels is as follows: ALL < TRACE < DEBUG < INFO < WARN < ERROR < FATAL < OFF.

What is log trace level?

TRACE. This is really fine-grained information—finer even than DEBUG. When you’re at this level, you’re basically looking to capture every detail you possibly can about the application’s behavior. This is likely to swamp your resources in production and is seriously diagnostic.
