  1. Cacti Network Monitoring and Graphing

  2. What is Cacti? • Network graphing solution for the RRDTool’s • RRDtool is the OpenSource industry standard, high performance data logging and graphing system for time series data. • RRDTool – “Round Robin Database” graphing on demand. • Simple SNMP tools for retrieving data, requires additional plugins for more specific hardware. • Complete frontend to RRDTool, which allows you to manage data sources, graphs and gather data.

  3. Telford College and Cacti • Monitor wireless network switches and Access points • Monitor all windows based servers • Also monitoring network switches and routers for up time and availability

  4. Why Cacti? • Free open source solution • Live community; support, plugins, templates • Easy to implement and set up • Little Linux or PHP knowledge required in the first instance • Alerting and monitoring features

  5. Cacti Features • Manage data sources – these include routers, switches, PCs, servers or any other snmp enabled device. Other devices limited to ping. • User Management – permissions for certain areas • Extendable using plugins, eg graphs, monitor, reports • CatiEZ simple setup • Cacti EZ already includes plugins within the base install

  6. How does cacti work • Group of PHP scripts connected to a MySQL database • Cacti takes data generated by polling your IT infrastructure - stores it in the RRDTool. Then it graphs the data, plain and simple. • Web interface for selecting data and generating graphs. • Mostly used to measure traffic/errors/packets/CPU utilization

  7. Demonstration

  8. Conclusion • Flexible due to templates and plugins • You can add graphs in hierarchies to make neat and useful websites of graphs • There are lots of resources, extensions, plugins - it gets more complicated then. Also a faster, SNMP poller is available (cactid) • Once you grow you need to use scripts/helpers to maintain cacti database. E.g. Netdot, Netdisco, IPPlan etc
