What are the supported values of REDASH_LOG_LEVEL?

In case of I want to log messeges more than warning level, could I set a parameter of REDASH_LOG_LEVEL?
At regulary situation, I need not INFO messages.

The default value of REDASH_LOG_LEVEL is INFO, only described.

This is basic matter, but waits for any advice.

Redash uses Python’s log levels.

Thanks you a lot!!
I will try continue to understand redash.
