Monitor disk usage of all your ec2 instances
================================================

Pulls disk usage stats(df) of all your instances and sends an email to the
specified email address. You can also add filters to get notifications when disk usage of a partition crosses a predefined value.

Run :
bundle install

Usage:
bundle exec irb
require "./disk_monit.rb"
ec2 = EC2Helpers.new(70, ec2 access key, ec2 secret key, "[email protected]")
ec2.get_disk_info_of(ec2.app_servers)

TODO:
  1. Ability to pull other stats.
  2. Dynamic filters.
