At each node in the tree, a Ganglia Meta Daemon (gmetad) periodically polls a collection of child data sources, parses the collected XML, saves all numeric, volatile metrics to round-robin databases and exports the aggregated XML over a TCP sockets to clients.
Although the web frontend to ganglia started as a simple HTML view of the XML tree, it has evolved into a system that keeps a colorful history of all collected data.
The Ganglia web frontend is written in the PHP scripting language, and uses graphs generated by gmetad to display history information.

Researchers have also identified the basal ganglia as the mediating site for the generation of goal-oriented behavior, the expression of emotions in an appropriate manner, and the suppression or inhibition of inappropriate responses, suggesting that dysfunction of this region plays a role in the pathogenesis of obsessive-compulsive behaviors.
