# 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
|
|
```
|
