Scrolls is a library for generating logs of the structure
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install scrolls
Scrolls follows the belief that logs should be treated as data. One way to think of them is the blood of your infrastructure. Logs are a realtime view of what is happening on your systems.
Need to know!
I apologize, some of these are a WIP.
- Sending logs to syslog using Scrolls
- Logging contexts
- Adding timestamps by default
- Misc Features
require 'scrolls' Scrolls.add_timestamp = true Scrolls.global_context(:app => "scrolls", :deploy => ENV["DEPLOY"]) Scrolls.log(:at => "test") Scrolls.context(:context => "block") do Scrolls.log(:at => "exec") end begin raise rescue Exception => e Scrolls.log_exception(:at => "raise", e) end

This library originated from various logging methods used internally at Heroku. Starting at version 0.2.0 Scrolls was ripped apart and restructured to provide a better foundation for the future. Tests and documentation were add at that point as well.
