[SECURITY] Fedora 7 Update: cacti-0.8.7b-1.fc7

Cacti is a complete frontend to RRDTool. It stores all of the necessary information to create graphs and populate 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 also handles the data gathering. There is SNMP support for those used to creating traffic graphs with MRTG.
