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.
- 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)
$ gem install last-resort
$ 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
If there is sufficient demand, we plan on adding more complicated schedules.
