Infrastructure Monitoring System

This is a monitoring system written mostly using Python and Bash.
Assets to be monitored send their service status to predefined location for that asset.
Service status is a string of the form "SERVICE STATUS|date|STATUS DESCRIPTION|STATUSCODE".
bin/enterprise_monitor.sh runs from cron every 60 seconds.
The system is capable of sending alerts as a text message or email. New alert delivery system can added.
It can send service recovery alerts as well. The entire system is tunable using config files in conf/
Alert recipients, assets and services to be monitored, alert frequency etc can be controlled from the config files.
I have used this in production since early 2010.
