Log4r using yml configurator: The log message won't include trace

199 views Asked by At

I'm trying to configure log4r with yml configuration file. Everything is configured as per the doc, but the log message won't include the class_name or trace. However it works fine with manual configuration without yml , but since it doesn't provide flexibility of configuring the logger, i can't do it that way. According to the doc, log4r config, logger should include trace with

trace: true

I added trace: true from config as well as from logger instance. But it's not working out. The %C in formatter pattern outputs the name of the logger used instead i.e.

logger = Log4r::Logger["development"]

gives log message in the format

150612 17:05:25 [development] DEBUG: hello there

My config.rb

application_config:
  # define all pre config ...
  pre_config:
    custom_levels:
      - DEBUG
      - INFO
      - PRINT
      - WARN
      - ERROR
      - FATAL
    global:
      level: DEBUG
      trace: 'true'
    root:
      level: DEBUG
      trace: 'true'
    parameters:
      - name   : x
        value  : aaa
      - name   : y
        value  : bbb

  # define all loggers ...
  loggers:
    - name      : development
      level     : DEBUG
      additive  : 'false'
      trace     : 'true'
      outputters:
        - stderr
        - logfile

    - name      : production
      level     : WARN
      additive  : 'false'
      trace     : 'true'
      outputters:
        - logfile


  # define all outputters (incl. formatters)
  outputters:
    - type     : StdoutOutputter
      name     : stderr
      level    : DEBUG
      formatter:
        date_pattern: '%y%m%d %H:%M:%S'
        pattern     : "%d [%c] %l: %m "
        type        : PatternFormatter


    - type        : DateFileOutputter
      name        : logfile
      level       : DEBUG
      date_pattern: '%Y%m%d'
      trunc       : 'false'
      dirname     : "logs"
      filename: "development.log"
      formatter   :
        date_pattern: '%y%m%d %H:%M:%S'
        pattern     : '%d %C %l: %m'
        type        : PatternFormatter

and my logger.rb class

require 'log4r'
require 'log4r/yamlconfigurator'
require 'log4r/outputter/datefileoutputter'
require 'log4r/outputter/consoleoutputters'    
yml_config = YAML.load_file(File.expand_path('../../yaml/log4r.yml', __FILE__))
Log4r::YamlConfigurator.decode_yaml yml_config['application_config']
module MyLogger
  def ms_logger
    Log4r::YamlConfigurator['class_name']= class_name

    return @ms_logger if @ms_logger

    @ms_logger = Log4r::Logger["environment"]
    @ms_logger.trace = true
    @ms_logger
  end

end

I included the module in the class where i need to add logger and called the logger method

ms_logger.info("hello there")

Why don't you try to configure manually without including YML configurator, that worked for me
