Cacti
- +Free, stable and extremely light on resources
- +Long-established SNMP graphing with a large body of community templates
- +Runs happily on modest hardware in small or isolated environments
- −Graphing-first: alerting requires plugins and is not a core strength
- −Interface and workflow are dated, and development pace is slow
Best for Small or isolated networks needing long-term interface graphing at no cost
Watch out Treat this as a graphing tool rather than a monitoring and alerting platform
Icinga
- +Free and open source with no device ceiling, and a far better interface than Nagios Core
- +Configuration as code fits infrastructure-as-code workflows well
- +Clustering and zones handle distributed and segmented networks properly
- −Initial setup is genuinely involved — expect to spend real time on it
- −Documentation assumes a level of familiarity that newcomers often lack
Best for Infrastructure teams who want configuration as code and no licence cost
Watch out This rewards investment; it punishes teams looking for something quick
