Log Message:
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.
