LTSV::Logger

Logger for LTSV(Labeled Tab-separated Values) format. See http://ltsv.org/ about LTSV.

Installation

Add this line to your application's Gemfile:

gem 'ltsv-logger'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ltsv-logger

Usage

Use Hash instead of String message:

# e.g.: rails
require 'ltsv-logger'

LTSV::Logger.open(File.join('log', "event_#{Rails.env}.log"))
ltsv = { method: "GET", uri: "/foo", status: 200 }
LTSV.logger.info ltsv # => time:2013-04-02 21:55:05 +0900 method:GET uri:/?max_id=9235&page=2 status:200

If logging Hash like request parameters, serialize Hash. e.g.:Hash.to_json:

# e.g.: rails
# params = { max_id: 9235, page: 2, controller: 'foo', action: 'bar' }

ltsv = { method: "GET", uri: "/?max_id=9235&page=2", status: 200, params: params.to_json }
LTSV.logger.info ltsv # => time:2013-04-02 21:55:05 +0900 method:GET uri:/?max_id=9235&page=2 status:200 params:{"max_id":"9235","page":"2","controller":"foo","action":"bar"}

Maybe, to use Marshal is not good, because it's difficult to deserialize with other programe launguage.

Other way, you can use String, as usual:

LTSV.logger.info "This is sample." # => time:2013-04-02 21:55:05 +0900 message:This is sample.
