Method: Logging::Logger#level=

Defined in:
lib/logging/logger.rb

#level=(level) ⇒ Object

call-seq:

level = :all

Set the level for this logger. The level can be either a String, a Symbol, or an Integer. An ArgumentError is raised if this is not the case.

There are two special levels – “all” and “off”. The former will enable log messages from this logger. The latter will disable all log messages from this logger.

Setting the logger level to nil will cause the parent’s logger level to be used.

Example:

log.level = :debug
log.level = "INFO"
log.level = 4
log.level = 'off'
log.level = :all

These produce an ArgumentError

log.level = Object
log.level = -1
log.level = 1_000_000_000_000
