  Introduction
  
  Cabot is a free, open-source, self-hosted infrastructure monitoring
  platform
  that provides some of the best features of PagerDuty, Server Density,
  Pingdom
  and Nagios without their cost and complexity.It provides a web interface
  that allows
  us to monitor services and send telephone, sms or hipchat/email alerts to
  your
  on-duty team if those services start misbehaving or go down .
