ianha/LastResort

Last Resort is a Ruby gem for monitoring email sent by automated services (monit, logging packages, external ping services, etc.) and calling your phone to tell you about the important ones. Using free and trial tiers available from context.io, twilio and heroku, Last Resort can be deployed in a reliable environment and perform up to 1500 emergency calls for free.

Requirements

Ruby 1.9.x
Accounts with context.io, twilio and optionally heroku, but don't worry -- our commandline utility will help you through the process.
Git (if you're deploying to Heroku)

Installation

$ gem install last-resort

Getting started

$ last-resort new my-awesome-project

This will create a new monitoring project with a sample my-awesome-project/schedule.rb file, and all that's needed to get up and running on a Rack server (or Heroku) quickly.

Example schedule.rb file

configure :from_env

# DEFINE YOUR CONTACTS

contact :ian, "416-123-1234"
contact :scott, "416-321-4321"
contact :victor, "416-123-4321"

# DEFINE WHAT EMAILS YOU WANT TO WATCH FOR

match :subject => /Server down/ # external ping service
match :subject => /Resource limit matched/ # monit

# DEFINE WHO TO CALL AND WHEN

between 19..22, :on => [:wednesday, :thursday] do
  call :victor
end

between :off_hours, :on => :weekdays do
  call :scott
end

between :all_hours, :on => :weekends do
  call [:ian, :scott, :victor]
end

Roadmap

If there is sufficient demand, we plan on adding more complicated schedules.
