Add this line to your application's Gemfile:

gem 'ext_logger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ext_logger

Usage

1. Initialization object (It automatically creates non-existent directories based on paths):

    logger = ExtLogger.new(log_path, {age: 7/'weekly', size: 1024000, split_format: '%Y%m%d%H%M', log_max_num: 5})

1. Output normal log (Extended logger.info):

    logger.info("log content")

1. Output debug log (Extended logger.info):

    logger.debug("log content")

1. Output error log (Extended logger.error):

    logger.error("log content")

1. Output warning log (Extended logger.warn):

    logger.warn("log content")

1. Output fatal log (Extended logger.fatal):

    logger.fatal("log content")

1. Output exception log (Extended logger.error):

    logger.exception(e) # when rescure Exception => e

1. Output memory usage (Extended logger.warn):

    logger.record_memory        # at the begin of programme
    logger.record_memory('end') # at the end of programme
