+# Check The Current Named Log Level
+
+I'm connected to a `rails console` session for an active Rails app. I want to
+check the current log level.
+
+```ruby
+> Rails.logger.level
+=> 1
+```
+
+The `1` doesn't mean much to me at a glance. I can translate that to the
+severity level using the `Logger::SEV_LABLE` constant.
+
+```ruby
+[44] pry(main)> Logger::SEV_LABEL[Rails.logger.level]
+=> "INFO"
+```
+
+Ah yes, `INFO`, that makes sense as the default.
+
+I can see all the severity levels by inspecting the constant itself.
+
+```ruby
+[45] pry(main)> Logger::SEV_LABEL
+=> ["DEBUG", "INFO", "WARN", "ERROR", "FATAL", "ANY"]
+```
+
+As I convenience, I can set the label using the index, the string, or even a
+symbol.
+
+```ruby
+> Rails.logger.level
+=> 1
+> Rails.logger.level = "WARN"
+=> "WARN"
+> Rails.logger.level
+=> 2
+> Rails.logger.level = :debug
+=> :debug
+> Rails.logger.level
+=> 0
+```
+
+See the [Debugging Rails Applications
+guide](https://guides.rubyonrails.org/debugging_rails_applications.html#log-levels)
+for more details.
