Paolog (aka Paolo el loggero)

Paolog is a live web log viewer for Rails apps.

Disclaimer

This project was based on browserlog gem. It was adapted to work with Rails 5.

Installation

The simplest way to install Paolog is to use Bundler.

gem 'paolog'

Paolog is bundled as a Rails engine. Mount it on config/routes.rb.

MyApp::Application.routes.draw do
  mount Paolog::Engine => '/paolog'
end

With this setup logs/development, logs/staging, logs/production and logs/test are automatically available on the browser.

Limit

By default, paolog with display your last 100 lines of your log. If you want to see more lines you can use the limit parameter: /paolog?limit=150

Note for production environments

For most production environments, it's recommended to not serve logs without authentication. This gem blocks by default any requests to logs/* in such production environment (i.e. RAILS_ENV=production).

In case you want to allow those logs to be displayed under production (e.g. staging servers), use the following initializer:

# config/initializers/allow_logs_on_production.rb
Paolog.config.allow_production_logs = true

Authentication

The gem uses HTTP Basic Authentication method. In order to work you should user and password in your encrypted credentials as follows:

paolog:
  user: paolo
  password: elloggero
