Xlog v0.0.1

Xlog - awesome logger for your Rails app. Logs everything you need in well-formatted view with timestamp, caller path and tags.

Usage

Log any info with .info method

Xlog.info('Some info text') # [2019-04-30 12:29:13 UTC] [ArtilesController.show] [info] Message: Some info text

Log important info with .warn method

Xlog.warn('Validation failed') # [2019-04-30 12:29:13 UTC] [ArticlesController.update] [warn] Message: Validation failed

Xlog has awesome .error and .and_raise_error methods

def index
  10 / 0  
  @orders = Order.all  
  rescue StandardError => e
    Xlog.and_raise_error(e, data: { params: params }, message: 'Some message text here')
end

...and the output

[2019-04-30 11:48:33 UTC] [Admin::OrdersController.index] [error] ZeroDivisionError: divided by 0. 
  | Message: Some message text here
  | Data: {:params=><ActionController::Parameters {"controller"=>"admin/orders", "action"=>"index"} permitted: false>} 
  | Error backtrace: 
  | /home/me/test_app/app/controllers/admin/orders_controller.rb:7:in `/'
  | /home/me/test_app/app/controllers/admin/orders_controller.rb:7:in `index'

The only difference between Xlog.error and Xlog.and_raise_error is that second one raises error after logging.

Xlog automatically defines Rails application name and environment. It writes logs into log/xlog_[environement].log

Xlog also supports custom tags

Xlog.tag_logger('custom_tag')
Xlog.info('Some text') # [2019-04-30 12:29:13 UTC] [ArtilesController.show] [info] [custom_tag] Message: Some info text

Clear tags with:

Xlog.clear_tags

Configuration

Xlog is ready to use right out of the box, but it's possible to reconfigure default logger. Default logger is simple Logger.new. Add this code to config/initializers/xlog.rb and set any custom logger you want.

Xlog.configure do |config|
  config.custom_logger = Logger.new(STDOUT) # or Logger.new('foo.log', 10, 1024000) or any other
end

It's possible to set third-party logger like Logentries(r7rapid)

require 'le'

Xlog.configure do |config|
  config.custom_logger = Le.new(logentries_key, 'eu', tag: true)
end
