Feel the Pulse of Your Infrastructure - Per-Second Visibility at Any Scale

True real-time means fixed 1-second data collection and 1-second visualization latency, resulting in sub-2-second total latency from event to insight. This matters because most operational anomalies last 2-10 seconds - invisible to systems averaging data over 10-60 second intervals. Per-second granularity catches microbursts, transient spikes, and cascading failures the moment they occur, enabling rapid iteration during incidents and immediate validation of changes.

Netdata’s distributed edge architecture processes data where it’s generated - each agent is a complete observability engine handling collection, storage, ML, and queries locally. This eliminates central bottlenecks that plague traditional monitoring. Parents aggregate streams from multiple agents, and active-active clustering provides high availability. Adding nodes adds capacity, not complexity - proven at 4.5+ billion metrics/second globally with 100,000+ node single installations.

Netdata has no practical cardinality limits. While Prometheus requires federation complexity or Thanos/Cortex architecture beyond 8M active series, Netdata handles unlimited dimensions through distributed storage and built-in protections. Each agent manages its own cardinality locally, and parents scale horizontally - no single point of failure or performance cliff. Monitor ephemeral containers, microservices, and dynamic workloads without constraints.

Netdata’s per-node pricing includes unlimited metrics, logs, users, and features - eliminating volume-based charges that spiral with scale. Edge processing eliminates egress costs (data stays local until viewed), and industry-leading compression (0.6 bytes/sample) reduces storage expenses. Traditional platforms charge per-host PLUS per-metric PLUS custom metrics PLUS log ingestion PLUS features - costs that multiply exponentially with infrastructure growth.

No. Netdata uses less than 5% CPU and 150MB RAM per agent while collecting thousands of metrics per second and running 18 ML models per metric. The University of Amsterdam study (ICSOC 2023) confirmed Netdata as the most energy-efficient monitoring solution - lowest CPU, RAM, and execution time impact - while collecting per-second data. Efficient engineering, not compromise, enables comprehensive real-time monitoring.

Netdata trains 18 unsupervised k-means models per metric using different time windows. Anomalies are flagged only when ALL models agree - achieving 99% false positive reduction in anomaly detection through consensus. The Anomaly Advisor automatically correlates anomalies across thousands of metrics, surfacing root cause in the top 30-50 most relevant results. AI explains issues in plain language with recommended actions - transforming hours of manual investigation into minutes of guided troubleshooting. Learn more about AI troubleshooting.

Yes, by design. Netdata’s unlimited cardinality architecture handles dynamic workloads without performance degradation. Auto-discovery detects new containers instantly, algorithmic dashboards adapt automatically, and ML trains on new metrics within 15 minutes. When containers disappear, their data remains accessible for historical analysis while UI updates cleanly. Perfect for Kubernetes, auto-scaling groups, and serverless environments. See Kubernetes monitoring.

Standalone Agents are complete observability systems - collection, storage, ML, alerts, dashboards - operating independently. Parents aggregate streams from multiple Agents, providing centralized dashboards, longer retention, and high availability through clustering. Agents can offload ML training, alerting, and storage to Parents, reducing production system load. Recommended architecture: Parent cluster every ~500 nodes (2M metrics/second). Learn more about Netdata Parents.

All observability data stays local on Agents and Parents - only metadata (node names, chart titles, alert configs) travels to Netdata Cloud for unified dashboards. Queries execute on Agents/Parents where data lives, with results streamed through Cloud. This architecture satisfies GDPR, HIPAA, and PCI DSS requirements automatically while enabling infrastructure-level visibility. On-premises Cloud deployment available for complete air-gapped environments. See data sovereignty details.

Minimal effort: (1) Deploy Agents via Ansible/Terraform/Helm with one-line install command, (2) Configure 2-3 Parent clusters for high availability and centralized dashboards, (3) Add credentials for protected services (databases, APIs), (4) Invite team members to Netdata Cloud. Zero configuration for auto-discovered services, algorithmic dashboards generate automatically, ML trains without tuning. Typical timeline: Days, not months.

Netdata delivers more granular visibility (per-second vs. 2-5 second intervals) at 90% cost reduction through edge-native architecture. While Datadog/Dynatrace centralize data in expensive cloud infrastructure with volume-based pricing, Netdata processes locally with per-node pricing. Both approaches achieve observability, but Netdata’s distributed model eliminates egress charges, maintains data sovereignty, and scales linearly without exponential cost increases. See detailed comparisons: Datadog, Dynatrace.

Yes. Start with free Community plan (5 nodes) or 14-day Business trial (unlimited nodes). Deploy on representative infrastructure subset, validate per-second visibility and ML capabilities, measure MTTR improvement, and project cost savings. Netdata’s zero-configuration approach delivers value within 60 seconds of installation - no lengthy POC required. Start free trial or explore live demo.

Business plan includes email/ticket support during business hours with SLA. Enterprise plan offers 24/7 availability, dedicated support team, phone support, and professional services (architecture design, deployment assistance, migration support). Community support available via Discord, forums, and GitHub discussions. Comprehensive documentation at learn.netdata.cloud.

Agents buffer data locally during network issues and automatically replay when connectivity restores - zero data loss. Each Agent operates independently with local dashboards, ML, and alerts continuing to function. Active-active Parent clustering provides automatic failover - Agents reconnect to available Parents seamlessly. Netdata Cloud distributes queries intelligently across available Agents/Parents. Result: Observability continues working even during infrastructure failures. See zero-downtime monitoring.
