Log4r-XMPP

Log4r-XMPP adds a XMPP/Jabber outputter to Log4r.

$ gem install log4r-xmpp

The following gems are required to use Log4r-XMPP:

• log4r

• xmpp4r (home.gna.org/xmpp4r)

• Do NOT include Log4r into your namespace! XMPP4r uses the generic Logger library and would become present in your namespace.

Requiring ‘log4r-xmpp’ will add an XMPPOutputter to Log4r. It is as simple as using any other Log4r::Outputter and can use most formatters in addition to the default.

:buffsize   => The number of logging events to buffer before sending (default 1)
:username   => Sending user's XMPP/Jabber account username
:password   => Sending user's XMPP/Jabber account password
:resource   => Optional sending user's XMPP/Jabber resource (default 'Log4r')
:recipients => An array of accounts to send Log4r log statements to

require 'log4r-xmpp'

options = { :buffsize   => 10,
            :username   => 'log4r@example.com',
            :password   => 'secret',
            :resource   => 'Log4r',
            :recipients => ['recipient1@example.com', 'recipient2@example.com']
          }

outputter = Log4r::XMPPOutputter.new('xmpp', options)

mylog = Log4r::Logger.new 'mylog'
mylog.outputters = outputter

mylog.debug "This is a test message sent at level DEBUG"

Requiring ‘log4r-xmpp/yamlconfigurator’ will patch Log4r::YamlConfigurator to accept an array list of recipients. Substitutions are still taken into consideration.

XMPP4r’s logger facility logs to an internal logger named ‘xmpp4r’. Attach an outputter to view additional warning information.
