Add current time before log message

Question

I created a custom logger for my application, called CRON_LOG, just by adding this piece of code to config/environment.rb

CRON_LOG = Logger.new(\"#{Rails.root}/l         


        

Answer 1

You can redefine the proper method (e.g. adding the following to environment.rb or in an initializer):

class Logger
  def format_message(severity, timestamp, progname, msg)
    "#{timestamp} (#{$$}) #{msg}\n"
  end
end

[Caution: this could disrupt other loggers; see Stephen's answer for a safe solution - jph]

Answer 2

The easiest way to make a SysLog-formatted logger is to assign a formatter directly:

logger = Logger.new Rails.root.join('path', 'to', 'log')
logger.formatter = Logger::Formatter.new
logger.info 'Hello, world!'
# Writes:
#
#   I, [2011-06-02T20:02:34.579501 #15444]  INFO -- : Hello, world!
