Module: RTKIT::Logging

Included in:

RTKIT

Defined in:

lib/rtkit/logging.rb

Overview

This module handles logging functionality.

Logging functionality uses the Standard library’s Logger class. To properly handle progname, which inside the RTKIT module is simply “RTKIT”, in all cases, we use an implementation with a proxy class.

Examples

require 'rtkit'
include RTKIT

# Logging to STDOUT with DEBUG level:
RTKIT.logger = Logger.new(STDOUT)
RTKIT.logger.level = Logger::DEBUG

# Logging to a file:
RTKIT.logger = Logger.new('my_logfile.log')

# Combine an external logger with RTKIT:
logger = Logger.new(STDOUT)
logger.progname = "MY_APP"
RTKIT.logger = logger
# Now you can call the logger in the following ways:
RTKIT.logger.info "Message"               # => "RTKIT: Message"
RTKIT.logger.info("MY_MODULE) {"Message"} # => "MY_MODULE: Message"
logger.info "Message"                     # => "MY_APP: Message"

For more information, please read the Standard library Logger documentation.
