Cacti is a complete frontend to rrdtool, it stores all of the necessary information to create graphs and populates them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain Graphs, Data Sources, and Round Robin Archives in a database, cacti handles the data gathering also. There is also SNMP support for those used to creating traffic graphs with MRTG. The Plugin Architecture for Cacti was designed to be both simple in nature and robust enough to allow freedom to do almost anything in Cacti. The Plugin Architecture for Cacti is integrated into this package.
