What is Plugin Architecture ?

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. Cacti itself is designed nicely enough that integrating into it is fairly easy with very little modifications necessary.

What is the different between Cacti Plugins and Plugin Architecture?

Cacti Plugins is plugins to support cacti itself, Plugin architecture is just design to manage cacti plugins and install cacti plugin on the fly.

I have a problem when my server reach 100MB++ traffic in my Cacti Server.
All my cacti graph will suddenly spike and the graph will show an abnormal traffic.

After i searching google and found actually cacti can solved my traffic more than 100MB ++ with graph template with 64bit counter.

But the problem is i can't have my cacti graph to show me 95th percentile on 64bit counter graph.

What is Cacti ?

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 handles the data gathering. There is also SNMP support for those used to creating traffic graphs with MRTG.
