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
Datadog Network Monitoring
- +Best-in-class dashboards and correlation with application and infrastructure telemetry
- +Very large integration catalogue across cloud and on-premises sources
- +Network Performance Monitoring ties flow data to service dependencies
- −SaaS only, and among the most expensive options once host and flow volume are counted
- −Cost visibility is poor until the first full month's bill arrives
Best for Cloud-native teams already standardised on Datadog for observability
Watch out Model the bill against realistic host and flow volume before committing
