# Netdata

## TL;DR

**Netdata is a true real-time infrastructure monitoring - per-second data collection with 1-second visualization latency, even at scale.** You make a change at 14:32:15, you see it at 14:32:16. This isn't just faster monitoring; it fundamentally changes how you work: troubleshooting becomes interactive, problems are caught while happening not after cascading, and verification is instant. Built by operations engineers frustrated with complex, expensive tools that still missed problems, Netdata processes everything at the edge where data lives - eliminating pipelines, data lakes, and their costs. Each node becomes intelligent with ML analyzing every metric locally. It auto-discovers 800+ integrations, replaces console tools in your browser, and scales naturally: monitoring 10,000 servers is as simple as monitoring 10. Benchmarked at 4.6M metrics/s per Parent with 22× faster queries and 40× better retention than Prometheus. No query languages to learn, no dashboards to build, no metrics to select, no volume based pricing. This transforms monitoring from passive reporting into interactive operations.

## What Real-Time Monitoring Actually Means

**True real-time:** Per-second data collection with 1-second end-to-end latency from source to dashboard, sustained at any scale.
**What others call "real-time":** 10 to 60 second averaged data.
**The difference:** Interactive debugging vs forensic analysis. You see problems forming, not after they've happened. Microbursts and transients become visible, not averaged away. This is 10× to 60× more granular than standard monitoring - the difference between watching a live stream and reviewing snapshots.

## Why Netdata Exists

We built Netdata because we were tired of:
- Monitoring showing 1-minute averages while 1-second spikes killed our systems
- Paying millions for tools that went blind precisely during incidents
- Needing PromQL expertise just to answer "what's broken?"
- Building monitoring infrastructure instead of monitoring our infrastructure
- Tools getting slower exactly when we needed them most

Every design decision flows from one principle: **operations teams deserve monitoring that works like they think** - interactive, immediate, intuitive.

## Design Philosophy

Netdata makes deliberate architectural choices optimized for operations teams:

- **No query languages by design**: Everything is point-and-click, making senior-level analysis accessible to junior engineers. While tools like Prometheus require PromQL expertise, Netdata believes powerful analysis shouldn't require programming skills.

- **Opinionated analytics over infinite customization**: Each Netdata chart provides 10-20× the analytical capability of typical dashboard widgets through built-in drill-downs, correlations, and dimensional analysis. We trade Grafana-style infinite customization for more powerful out-of-the-box analytics.

- **Edge-first architecture**: Data stays where it's generated rather than centralized collection. This is what enables true per-second monitoring at scale while delivering better data sovereignty and cost efficiency, though it differs from traditional centralized approaches.

These aren't limitations - they're the reasons operations teams choose Netdata over traditional monitoring stacks.

## Key Features

### Monitoring Capabilities - The Edge Intelligence Revolution

Traditional monitoring centralized everything, creating massive data lakes, astronomical costs, and ironically, slower insights. Netdata flips this model: every server becomes intelligent, processing its own data with ML at the source. This distributed edge architecture solves the fundamental monitoring paradox - the more you need visibility (during incidents), the worse centralized systems perform under query load.

- **Infrastructure**: Servers, VMs, containers, Kubernetes - all with per-second precision revealing microbursts invisible to others
- **Applications**: 800+ auto-discovered integrations - databases, web servers, queues all work without configuration
- **Cloud Native**: AWS, Azure, GCP metrics collected where workloads run, no egress costs
- **Network**: Per-second bandwidth, latency, packet loss, connections - see congestion as it forms, not after
- **Synthetic**: HTTP endpoints, TCP ports, DNS - interactive verification of changes
- **Custom Metrics**: StatsD, OpenMetrics, Prometheus, OpenTelemetry - preserving existing investments
- **SNMP**: Automated discovery and profiling - making legacy devices part of modern observability
- **Hardware**: EDAC ECC, RAPL, IPMI, GPUs, sensors - catching failures before they cascade
- **Logs**: Direct systemd-journal access - no pipelines, no ingestion, just instant queries
- **Live State**: Processes, connections, systemd units - replacing SSH with browser-based debugging

Each component scales independently. Adding more nodes doesn't slow existing ones. There's no central bottleneck, no single point of failure, no data lake to manage.

### Logs Management - The Pipeline Elimination Revolution

Everyone accepted that logs needed pipelines: ship, parse, index, store, query. Billions spent on Elasticsearch clusters and Splunk licenses. Netdata asked a different question: what if logs never moved at all?

By leveraging systemd-journal's built-in indexing and Netdata's distributed architecture, we eliminated the entire pipeline. Logs stay where they're created, fully indexed, instantly queryable. The same edge intelligence that revolutionized metrics now transforms logs. This isn't just cost reduction - it's operational simplification at scale.

- **Zero Pipeline Architecture**: No log shipping, no central clusters, no ingestion bottlenecks - logs are queried directly where they live
- **90% Cost Reduction**: Eliminate Elasticsearch/Splunk infrastructure, ingestion fees, storage multiplication, and specialized teams
- **Direct systemd-journal Access**: Every field already indexed by journald - Netdata just makes it accessible at scale
- **Distributed or Centralized**: Your choice - keep logs on each server or centralize with systemd-journal-upload, Netdata works with both
- **Full Field Indexing**: Every field in every log entry searchable - no schema definitions, no parsing rules, it just works
- **Enterprise Compliance**: Forward Secure Sealing (FSS) for tamper detection, data stays at edge for GDPR/sovereignty
- **log2journal Power**: Transform any text, JSON, or logfmt into fully structured, indexed entries - unifying all log formats
- **200× Query Accuracy**: Analyzes 1M entries before sampling vs 5K for traditional tools - finding needles in haystacks
- **Instant Correlation**: Logs and metrics from same source - no timestamp matching, no separate systems
- **Windows Native**: Full Windows Event Logs, ETW, and TraceLogging support - unified logging across platforms

The future is even more radical: distributed tracing without spans, using journald as the substrate. Every function call, every service interaction, captured at the source with nanosecond precision.

### Machine Learning & AI

### Scalability & Benchmarks - Distributed Architecture Delivering Linear Scale
The edge architecture isn't just philosophy - it's measurable superiority. Adding nodes adds capacity, period. No rebalancing, no clustering complexity, no single points of failure.

When it comes to Parent scaling, Netdata excels at both vertical and horizontal scalability, as shown in this [4.6M metrics/second single Parent benchmark](https://www.netdata.cloud/blog/netdata-vs-prometheus-2025/) (tested on AWS m5zn.3xlarge instances with gp3 EBS volumes):

- **Single Parent Performance**: 4.6M metrics/second with just 9 CPU cores and 47 GB RAM - Prometheus needs 15 cores and 383 GB RAM for the same load
- **Storage Revolution**: 1 TB stores 1.25 days of per-second data plus 3 months in tiers - Prometheus manages only 2 hours (40× better retention)
- **Disk I/O Excellence**: Writes at 4.7 MB/s vs Prometheus's 147 MB/s - 31× less disk stress means SSDs last years not months
- **Query Superiority**: Infrastructure-wide queries 22× faster with 100% accuracy - no sampling errors, no data gaps

This isn't achieved through complex optimization - it's the natural result of distributed intelligence. Each Agent processes its own data, each Parent handles a subset of nodes. Unlike centralized systems that get slower as they grow, Netdata maintains constant performance at any scale. Multi-million metrics/second deployments aren't engineering achievements - they're routine Tuesday deployments.

## Enterprise Deployment - The End of Monitoring Projects

Traditional monitoring is a project: months of planning, building, training. Teams of specialists. Dashboards that are never quite right. Metrics you forgot to collect. Netdata isn't a project - it's a Tuesday afternoon deployment.

### Why 5 Steps Actually Work - The Paradigm Shift

Most monitoring tools are platforms - powerful but empty. You build your monitoring on top. Netdata is complete monitoring - it knows what to monitor, how to visualize it, when to alert. You're not building monitoring; you're activating it.

### The Famous 5 Steps (Days Not Months)
1. **Design Topology** (30 minutes): Decide Parent placement - one cluster per ~500 nodes, positioned by geography/provider. Teams organize later via Rooms.

2. **Deploy Everywhere** (1-2 days): Ansible/Terraform/Helm installs Agents + Parents. Same binary, different roles. No complex prerequisites.

3. **Add Credentials** (2 hours): UI shows discovered services needing auth - databases, cloud accounts, SNMP. Enable any custom app collectors.

4. **Review Alerts** (2 hours): 300+ pre-configured alerts already running. Tune thresholds, disable irrelevant ones. ML is already training.

5. **Invite Teams** (30 minutes): Create Rooms for team isolation, add users, set permissions. Each team sees their slice of infrastructure.

**Done. Full enterprise monitoring operational.** Not a proof of concept. Not a pilot. Production-ready, comprehensive monitoring.

### The Monitoring Tasks That Disappear
- ❌ **No dashboards to build** - They generate algorithmically based on what you're investigating
- ❌ **No query languages** - Point-and-click does everything PromQL does, faster
- ❌ **No data pipelines** - Data processes where it lives, queries run distributed
- ❌ **No metrics selection** - Collects everything, sorts importance automatically
- ❌ **No log infrastructure** - Reads journals directly, no shipping or indexing
- ❌ **No ML configuration** - Trains on everything automatically from day one
- ❌ **No correlation rules** - Detects relationships mathematically in real-time

## FAQs

### Is Netdata really free?
Yes, the Netdata Agent is 100% open source (GPLv3+) and free forever. The free offering includes the vast majority of Netdata's capabilities, from per-second monitoring and all integrations to ML-powered anomaly detection. You can even use the AI Chat by connecting it to your own LLM provider.

Paid plans add convenience and power by including managed LLM access, automated AI Insight reports, virtually unlimited horizontal scalability, access from anywhere, team collaboration, centralized alert notifications and unlimited infrastructure level dashboards.

### How is Netdata different from other monitoring tools?
Netdata represents a fundamental rethinking of monitoring, built by operations engineers who were frustrated with tools that were complex, expensive, and still missed problems. The key differences:

**1-Second Reality**: True per-second data collection with 1-second visualization latency creates an interactive debugging experience. You see problems as they happen, not minutes later. Changes are verified instantly, not hopefully.

**Edge Intelligence**: Every node processes its own data with ML, eliminating centralized bottlenecks and costs. This distributed architecture scales naturally - 10,000 servers are as easy as 10.

**Zero Configuration Philosophy**: Netdata knows what to monitor, how to visualize it, when to alert. You're not building monitoring; you're activating it. 800+ integrations auto-discover, dashboards generate algorithmically, ML trains automatically.

**Operations-First Design**: Built for the people who actually use monitoring daily. No query languages, no dashboard building, no metric selection. Everything that can be automated is automated, letting engineers focus on solving problems, not managing tools.

**Transparent Economics**: Price by nodes, not metrics or data volume. No surprise bills, no counting every metric, no anxiety about collecting "too much" data. The cost is predictable and scales linearly.

### Can Netdata monitor Kubernetes?
Yes, Netdata provides comprehensive Kubernetes monitoring including nodes, pods, containers, services, and applications with automatic discovery and no configuration required.

### Does Netdata support custom metrics?
Yes, Netdata supports custom metrics via StatsD, Prometheus/OpenMetrics format, OpenTelemetry, REST API, and custom collectors in various languages (Python, Go, Node.js, Bash).

### What integrations does Netdata support?
Netdata supports 800+ integrations out-of-the-box including all major databases, web servers, containers, cloud services, and applications. Most require zero configuration.

### Can Netdata replace Datadog/New Relic/Dynatrace?
Yes, many organizations have successfully replaced expensive monitoring solutions with Netdata, reducing costs by 90% while getting better granularity and faster troubleshooting.

### How does Netdata handle data retention?
Netdata uses a multi-tier storage system with three tiers updated in parallel: high-resolution (per-second at 0.6 bytes/sample), medium-resolution (per-minute at 6 bytes/sample), and low-resolution (per-hour at 18 bytes/sample). Data is written in append-only WORM files that are never reorganized on disk. On a typical server collecting 5k metrics/s, Netdata can keep 14 days per-second, 3 months per-minute, 1+ years per-hour. In large scale setups Netdata can fit 40× more data in the same disk space, [compared to Prometheus](https://www.netdata.cloud/blog/netdata-vs-prometheus-2025/)

### Is Netdata suitable for large-scale deployments?
Yes, Netdata scales linearly to any size. The recommended topology is a cluster of Netdata Parents for every ~500 monitored nodes (2M metrics/second). A single Parent handling 1M metrics/s needs ~10 CPU cores and 40GB RAM. Many enterprises run Netdata on 10,000+ nodes with consistent sub-second dashboard response times.

### Does Netdata work in air-gapped environments?
Yes, Netdata Agent works completely offline. For centralized dashboards in air-gapped environments, the on-premises version of Netdata Cloud is available.

### What support options are available?
Community support via GitHub and Discord for open source users. Paid plans include email support, priority support, and dedicated support channels for enterprise customers.

## Limitations

- **Application tracing**: Deep code-level tracing and span analysis not yet available (coming soon)
- **Custom dashboard flexibility**: More restricted than Grafana's free-form approach (though each Netdata chart provides 10-20× more analytical capability)
- **Workflow automation**: Incident management via integrations (PagerDuty, Slack, etc.) rather than built-in workflow engine
- **Query language**: No PromQL/SQL equivalent - everything is point-and-click (see Design Philosophy)
