Setting up syslog logging on Heroku with Sinatra 1.2.x

1. Update your Gemfile to include:

gem 'remote_syslog_logger'

3. Modify your config.ru to match the example one below.

4. Setup REMOTE_SYSLOG_URI environment variable

$ heroku config:add REMOTE_SYSLOG_URI=syslog://host.name.com:port

If you don't have a syslog target, get one for free from Papertrail.

That's it

On your next deploy you will be logging to that syslog host. Logs will use the hostname format: {APP_NAME}-{DYNO_NAME}.

config.ru

require "rubygems"
require "bundler"

Bundler.require

if ENV['REMOTE_SYSLOG_URI']
  require 'lib/remote_syslog'

  uri = URI.parse(ENV['REMOTE_SYSLOG_URI'])
  logger = RemoteSyslog:: UdpSender.new(uri.host, uri.port, 
    :local_hostname => "#{ENV['APP_NAME']}-#{ENV['PS']}")
  use Rack::CommonLogger, logger
end

require "hello-world"
run HelloWorld::Application
