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
LibreNMS
- +Excellent auto-discovery across a very wide range of network vendors
- +Free with no device limit, and a distributed poller model for larger estates
- +Strong fit for ISP and service provider environments
- −Polling interval is conventionally five minutes — not built for sub-minute resolution
- −Alerting and reporting are functional rather than polished
Best for Network teams and service providers wanting broad device coverage at no licence cost
Watch out If you need second-level granularity, this is the wrong tool architecturally
