Tagged loggers like ActiveSupport::TaggedLogger make logging both named and unnamed tags visible for better application debugging. Currently log_tags only supported an array of tags such as:
config.log_tags = [ :remote_ip, ->(request) { some_computed_value } ] However as this list gets long it has two issues: 1. Parsing JSON logs requires positional references (ie remote_ip will always be at some index) 2. Some tags look similar and are hard to discern in a log message. For example a datadog trace id and epoch time look indistinguishable to a human reading those logs I submitted https://github.com/rails/rails/pull/38009 as one solution -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
