help Cacti FAQ

What data source does Cacti commonly use for network graphs?

Cacti commonly collects device statistics through SNMP and stores the results for graphing. It is often used for interfaces, bandwidth, CPU, memory, and similar time-series data.

Is Cacti free and open source?

Yes. Cacti is open-source monitoring software that can be installed on infrastructure managed by the user. The operating cost comes from hosting, maintenance, and administration rather than a per-device SaaS fee.

Can Cacti monitor routers and switches from different vendors?

Yes, when the devices expose compatible SNMP objects or templates. Cacti's templates help map vendor-specific metrics into usable graphs.

How is Cacti different from Nagios?

Cacti is especially known for collecting and graphing time-series performance data, while Nagios is widely used for host and service checks with alerts. Many teams use one or both because graphing and alerting are separate needs.
