Network Performance Monitoring & Observability
Monitor Latency, QoE, and SLA Compliance Across Every Environment
Users don’t care whether a slowdown originates in your data center, a cloud provider, or the link in between, they just know the application feels slow. Network performance monitoring with ntopng gives you the visibility to find out exactly where, catching latency spikes, bottlenecks, and SLA violations before they become support tickets.
The Problem
Performance Issues Hide Across Layers
Modern infrastructure spans physical networks, virtualized environments, and cloud services, and a performance problem can originate in any of them. Without unified visibility, teams waste time ruling out layers one by one while users wait.
Common blind spots include:
- No visibility into per-application or per-host latency, only aggregate link utilization.
- No way to correlate a performance complaint with what was actually happening on the network at that moment.
- SLA compliance tracked manually or after the fact, instead of continuously.
The Solution
Unified Performance Visibility with ntopng
- Real-time performance metrics: ntopng continuously measures round-trip time, retransmissions, jitter, and throughput per host, application, and interface, across physical, virtual, and cloud networks.
- Quality of Experience (QoE) scoring: see how network conditions translate into actual user experience for key applications, not just raw packet counts.
- Historical baselines: compare current performance against historical norms to quickly tell whether a slowdown is a new issue or expected variation.
- Application-aware analysis (nDPI): because ntopng classifies traffic at Layer 7, you can isolate performance data by specific application, not just by port or protocol guesswork.
- Distributed monitoring (nProbe): deploy flow probes at branch offices, WAN edges, or cloud environments to measure performance close to the source, then centralize the data in ntopng for a single view.
Use Cases
Diagnosing intermittent latency
A VoIP application has occasional call quality issues. ntopng correlates jitter and packet loss with specific time windows and paths, identifying a congested link that only saturates during peak hours.
Verifying SLA compliance
A managed service provider needs to prove uptime and latency commitments to a client. Historical performance data from ntopng provides an auditable record, without manual log correlation.
Spotting a bottleneck before users complain
Interface throughput trending toward saturation triggers an alert, giving the network team time to act before the link actually degrades service.
Comparing on-prem and cloud performance
A hybrid environment shows a cloud-hosted application performing worse than its on-prem counterpart. Side-by-side metrics pinpoint whether the issue is network path, cloud provider, or application configuration.
Why it matters
Why Teams Use ntopng for Performance Monitoring
- Cross-environment visibility: physical, virtual, and cloud networks in one console.
- Application-level detail: not just link utilization, but per-app and per-host performance.
- Historical context: every metric is comparable against past baselines, not just viewed in isolation.
- Scales with your network: from a single site to distributed, high-throughput environments.
