Rotozipper

Rotozipper is a simple Ruby gem which aims to simplify log rotation and zipping.

Add this line to your application's Gemfile:

gem 'rotozipper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rotozipper

Usage is simple. The gem provides a method launch of the Rotozipper module which takes three arguments:

• glob_path (required): the path in glob form of the folder where your logs are stored. For example, in a Rails application, you can set it to log/*.log.
• output_path (optional): the path where you want to save the rotozipped logs. Defaults to a relative history folder.
• logger_path (optional): the path of a log file where you want to store Rotozipper's operative logs. Defaults to STDOUT.

For example, to rotozip logs of a Rails application, you can execute:

Rotozipper.launch 'log/*.log', 'log/history'

This command will compress all the *.log files in the log folder, and the move them to log/history folder, adding a timestamp to keep track of the moment. The original files will be truncated to 0 bytes.

Rotozipper has whenever as a gem dependency, so if you need to schedule the rotozipping of your logs, you can simply create a file named config/schedule.rb in your Rails application, and then add the following lines:

# config/schedule.rb

every :week, at: '00:00' do
  runner %{ Rotozipper.launch 'log/*.log', 'log/history' }
end

And then schedule it by running the command whenever --update-crontab. Please refer to whenever documentation to know more about it features.
