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 .
