=AMQPLogging

A ruby logger class that logs to an {AMQP}[http://www.amqp.org/] exchange

==Basic Configuration By default the logs are routed to the host, exchange and key specified in DEFAULT_OPTIONS. You can change the configuration when creating the logger object by specifying an argument hash:

require 'amqp_logging'

logging_config = { :routing_key => "applogging", :host => AppConfig.amqp_logging.host, :exchange => AppConfig.amqp_logging.exchange }

logger = AMQPLogging::Logger.new(logging_config) config.logger = logger

==Routing Keys

You can set the routing key with a string or use a generator that respondes to call, receives the logline as the first argument and returns the routing key.

Example:

You can use a lambda or whatever responds to #call as the routing key generator

AMQPRoutingKeyGenerator = lambda do |logline| if logline =~ /(?:engine[([^]]*)]): (Completed in|Processing|Session ID)?/ key = "logs.app.#{$1}" key << ".statistics" unless $2.nil? else key = "logs.app.system" end key end

AMQPLogging::Logger.new($stdout, :routing_key => AMQPRoutingKeyGenerator)

==Fallback to disk

The support for a fallback logdevice was removed with version 0.5.0. A multi logger thatallows you get the same behaviour will follow soonish.
