Introduction

Cacti is an open source, web-based graphing tool designed as a frontend to RRDtool's data storage and graphing functionality. Cacti allows a user to poll services at predetermined intervals and graph the resulting data. It is generally used to graph time-series data like CPU load and bandwidth use. A common usage is to query network switch or router interfaces via SNMP to monitor network traffic.

CSE monitors its compute systems' renewable hardware resources with Cacti. We monitor these series of data over time:

• number of logged-in users
• number of processes
• network traffic
• per-filesystem disk usage
• CPU usage
• memory usage
• system load
