SysLogger

Ruby Logger for interacting with syslog using RFC 5424 format.

syslogger is a wrapper around the standard ruby Logger for logging via syslog. Messages passed to syslogger are formatted by default with RFC 5424. It allows for communication through sockets or files.

gem install syslogger5424

or add the following line to Gemfile:

gem 'syslogger5424'

and run bundle install from your shell.

require 'syslogger'

log = SysLogger.new
log.info("Hello\nWorld")
# <190>1 2014-10-02T11:59:52.524177-07:00 HOSTNAME - - - [meta x-group="79748942"] Hello
# <190>1 2014-10-02T11:59:52.524177-07:00 HOSTNAME - - - [meta x-group="79748942"] World

When strings containing newlines are logged, lines are seperated and written. These lines are grouped together by the meta SD-ID under the x-group parameter.

The default facility is local7 (23). To change this or any other information in the header, set the logger's formatter after creation.

require 'syslogger'

log = SysLogger.new
log.formatter = SysLogger::Formatter::RFC5424.new("APP-NAME", "PROCID", "MSGID", "kern")

log.info("Hello\nWorld")
# <6>1 2014-10-02T12:16:54.222893-07:00 HOSTNAME APP-NAME PROCID MSGID [meta x-group="78784030"] Hello
# <6>1 2014-10-02T12:16:54.222893-07:00 HOSTNAME APP-NAME PROCID MSGID [meta x-group="78784030"] World

By default, SysLogger will write to $stdout. To override, either pass a device to the constructor or a block that can be called to create the device.

require 'syslogger'

log = SysLogger.new(&SysLogger::Creators::unix_dgram_socket("/path/to/datagram/socket"))
log.info("Hello\nWorld")
