NETDATA VS CACTI

From 5-Minute SNMP Graphs to Per-Second Network Observability

Q: Can Netdata replace Cacti for SNMP device monitoring?

Yes. Netdata supports SNMPv1/v2c/v3 polling with 100+ vendor profiles and zero-configuration auto-discovery. It covers the same routers, switches, and firewalls Cacti monitors — but at per-second granularity with automatic dashboards. Learn more about SNMP monitoring.

Q: What does Netdata do that Cacti cannot?

Netdata provides per-second data collection (vs Cacti’s 5-minute default), native NetFlow/IPFIX/sFlow analysis, live topology mapping via LLDP/CDP/BGP/OSPF, ML-powered anomaly detection with 18 models per metric, native SNMP trap collection with 150K+ definitions, and full-stack monitoring covering servers, containers, applications, and logs — all in one platform.

Q: What does Cacti do better than Netdata?

Cacti has a very large, mature community template ecosystem built over decades. For organizations that need simple, long-term SNMP utilization graphs of router and switch interfaces — and nothing else — Cacti is a proven, lightweight, and reliable choice. Its RRDtool backend is battle-tested for historical trend visualization.

Q: Is Netdata open source like Cacti?

Yes. Netdata’s agents are open-source and free to run. Netdata also offers optional Cloud (SaaS) and on-premises Parent services for fleet-scale dashboards, collaboration, and advanced features. Cacti is fully open-source under GPL and entirely self-hosted.

Q: Does Netdata support SNMP traps?

Yes. Netdata includes a native SNMP trap receiver supporting v1/v2c/v3 and INFORMs, shipping 150,000+ trap definitions from 800+ vendors as severity-tagged structured logs. Explore SNMP trap monitoring.

Q: How does Netdata's polling frequency compare to Cacti?

Netdata collects metrics every second by default with sub-second dashboard visualization. Cacti’s default polling cycle is 5 minutes (300 seconds). While Cacti can be tuned to 1-minute intervals with the Spine poller, it cannot match per-second granularity — and its RRDtool storage decays resolution over time.

Q: Can I use Netdata and Cacti together?

Yes. Some teams use Cacti for legacy long-term SNMP utilization graphs while deploying Netdata for real-time troubleshooting, flow analysis, anomaly detection, and full-stack observability. Netdata’s open architecture supports OpenMetrics, OpenTelemetry, and StatsD, so data can flow between systems.

Q: Does Netdata support NetFlow and IPFIX analysis?

Yes, natively. Netdata includes a built-in flow analyzer supporting NetFlow v5/v7/v9, IPFIX, and sFlow v5 with Sankey diagrams, geographic maps down to street level, top talkers analysis, and GeoIP/ASN enrichment. Explore the flow analyzer.

Q: How hard is it to migrate from Cacti to Netdata?

Netdata’s zero-configuration auto-discovery means you install agents, enable SNMP discovery, and dashboards build themselves — no manual template binding. For hundreds or thousands of nodes, Netdata typically deploys in hours to days, compared to the weeks or months of manual configuration traditional tools require. Read the network monitoring guides.

Q: Does Netdata have network configuration management (NCM)?

No. Netdata does not provide network configuration backup or change management (NCM). It focuses on observability — monitoring, alerting, flow analysis, topology, and troubleshooting. If you need NCM, consider pairing Netdata with a dedicated configuration management tool.

Cacti has earned its place as a reliable, open-source SNMP graphing tool with a massive legacy install base. But when you need per-second visibility, native flow analysis, live topology, ML-powered anomaly detection, and full-stack observability in a single platform, the gap becomes structural — not incremental.

Netdata delivers real-time network monitoring with zero-configuration auto-discovery, native SNMP trap collection, built-in NetFlow/IPFIX/sFlow analysis, and live topology mapping — all unified with server, container, and application metrics in one platform.

Explore Network Monitoring See How It Works

Per-Second Visibility

Netdata collects metrics every second with sub-second dashboard latency. Cacti’s default 5-minute RRD polling hides transient spikes and microbursts that cause real incidents.

Native Flow Analysis

Built-in NetFlow v5/v7/v9, IPFIX, and sFlow v5 analysis with Sankey diagrams, geographic maps to street level, and GeoIP/ASN enrichment. No community plugins required.

Live Topology Mapping

Automatic LLDP/CDP/BGP/OSPF device fabric discovery plus per-process and per-container connection maps. Click any node to see dependencies and dependants instantly.

ML Anomaly Detection

18 unsupervised ML models per metric with ~99% fewer false positives. Cacti relies on static Thold thresholds that require constant manual tuning.

Zero-Config Auto-Discovery

100+ vendor SNMP profiles with automatic device discovery. Cacti requires manual host and graph template assignment for every device.

Unified Full-Stack

Network, servers, containers, applications, and logs in one platform. Cacti is SNMP graphing only — you need additional tools for everything else.

What Changes When You Switch to Netdata

See Every Microburst in Real Time

Cacti’s 5-minute RRD polling averages away the transient spikes that cause packet loss and congestion. Netdata’s per-second collection captures every microburst, every link flap, every interface error — the moment it happens.

300x more granular than 5-min polling

Replace Manual Templates with Auto-Discovery

Cacti requires you to select and bind graph templates for every device manually. Netdata ships 100+ vendor SNMP profiles and automatically discovers devices, interfaces, and metrics — dashboards build themselves.
