Frontend (Web-based dynamic access) composition is a Linux configuration monitoring system performance software, the interface beautiful, rich, powerful and ganglia and rely on a webserver to show the status of the cluster, with RRDtool to store data and generate graphs, XML parsing is required so expat is required. Configuration file parsing requires libconfuse.

Ganglia is a monitoring server, cluster of open source software, can be used to express the recent one hours, the recent day, the recent week, the recent January. Recent year of server or cluster CPU load, memory, network, hard disk and other indicators.

The power of the ganglia is that the ganglia server can collect all the client data from the same network segment through a single client. The ganglia cluster server can collect all client data from its subordinates through a server. This system design means that a server can manage tens of thousands of machines through different tiers.

This function is unmatched by other mrtg,nagios,cacti.
