new ganglia interface
* Why a new interface ?
** To allow more options for graphing
** TO create different graph types
** To integrate alerting framework
** Creating a API model for integration with other Applications
** To easily create arbiruartary aggregate graphs for comparison

* How do we group the graphs ?
* A graph signifies a single metric historic pattern.
** Multiple metrics can be graphed in a single graph if it matches the following cretiria
** Different metrics but for same server grouped by "Metrics Group"
** Same metric with different servers grouped by "Metrics Group"

* Grouping via Metrics group if multiple metrics
