Getting Started

You can install Netdata on all major operating systems. To begin:

1. Install Netdata

Choose your platform and follow the installation guide:

• Linux Installation
• macOS
• FreeBSD
• Windows
• Docker Guide
• Kubernetes Setup

Note

You can access the Netdata UI at http://localhost:19999 (or http://NODE:19999 if remote).

2. Configure Collectors

Netdata auto-discovers most metrics, but you can manually configure some collectors:

• All collectors
• SNMP monitoring

3. Configure Alerts

You can use hundreds of built-in alerts and integrate with:

email, Slack, Telegram, PagerDuty, Discord, Microsoft Teams, and more.

Note

Email alerts work by default if there's a configured MTA.

4. Configure Parents

You can centralize dashboards, alerts, and storage with Netdata Parents:

• Streaming Reference

Note

You can use Netdata Parents for central dashboards, longer retention, and alert configuration.

5. Connect to Netdata Cloud

Sign in to Netdata Cloud and connect your nodes for:

• Access from anywhere
• Horizontal scalability and multi-node dashboards
• UI configuration for alerts and data collection
• Role-based access control
• Free tier available

Note

Netdata Cloud is optional. Your data stays in your infrastructure.

Loading

With each Agent you can:

1. Collect – Gather metrics from systems, containers, apps, logs, APIs, and synthetic checks.
2. Store – Save metrics to a high-efficiency, tiered time-series database.
3. Learn – Train ML models per metric using recent behavior.
4. Detect – Identify anomalies using trained ML models.
5. Check – Evaluate metrics against pre-set or custom alert rules.
6. Stream – Send metrics to Netdata Parents in real time.
7. Archive – Export metrics to Prometheus, InfluxDB, OpenTSDB, Graphite, and others.
8. Query – Access metrics via an API for dashboards or third-party tools.
9. Score – Use a scoring engine to find patterns and correlations across metrics.

FAQ

Is Netdata secure?

Yes. Netdata follows OpenSSF best practices, has a security-first design, and is regularly audited by the community.

• Security design
• Security policies and advisories

Does Netdata use a lot of resources?

No. Even with ML and per-second metrics, Netdata uses minimal resources.

• ~5% CPU and 150MiB RAM by default on production systems
• <1% CPU and ~100MiB RAM when ML and alerts are disabled and using ephemeral storage
• Parents scale to millions of metrics per second with appropriate hardware

You can use the Netdata Monitoring section in the dashboard to inspect its resource usage.

How much data retention is possible?

As much as your disk allows.

With Netdata you can use tiered retention:

• Tier 0: per-second resolution
• Tier 1: per-minute resolution
• Tier 2: per-hour resolution

These are queried automatically based on the zoom level.

Can Netdata scale to many servers?

Yes. With Netdata you can:

• Scale horizontally with many Agents
• Scale vertically with powerful Parents
• Scale infinitely via Netdata Cloud

You can use Netdata Cloud to merge many independent infrastructures into one logical view.

Is disk I/O a concern?

No. Netdata minimizes disk usage:

• Metrics are flushed to disk every 17 minutes, spread out evenly
• Uses direct I/O and compression (ZSTD)
• Can run entirely in RAM or stream to a Parent

You can use alloc or ram mode for no disk writes.

How is Netdata different from Prometheus + Grafana?

With Netdata you get a complete monitoring solution—not just tools.

• No manual setup or dashboards needed
• Built-in ML, alerts, dashboards, and correlations
• More efficient and easier to deploy

Performance comparison

How is Netdata different from commercial SaaS tools?

With Netdata you can store all metrics on your infrastructure—no sampling, no aggregation, no loss.

• High-resolution metrics by default
• ML per metric, not shared models
• Unlimited scalability without skyrocketing cost

Can Netdata run alongside Nagios, Zabbix, etc.?

Yes. You can use Netdata together with traditional tools.

With Netdata you get:

• Real-time, high-resolution monitoring
• Zero configuration and auto-generated dashboards
• Anomaly detection and advanced visualization

What if I feel overwhelmed?

You can start small:

• Use the dashboard's table of contents and search
• Explore anomaly scoring ("AR" toggle)
• Create custom dashboards in Netdata Cloud

Docs and guides

Do I have to use Netdata Cloud?

No. Netdata Cloud is optional.

Netdata works without it, but with Cloud you can:

• Access remotely with SSO
• Save dashboard customizations
• Configure alerts centrally
• Collaborate with role-based access

What telemetry does Netdata collect?

Anonymous telemetry helps improve the product. You can disable it:

• Add --disable-telemetry to the installer, or
• Create /etc/netdata/.opt-out-from-anonymous-statistics and restart Netdata

Telemetry helps us understand usage, not track users. No private data is collected.

Who uses Netdata?

You'll join users including:

• Major companies (Amazon, ABN AMRO Bank, Facebook, Google, IBM, Intel, Netflix, Samsung)
• Universities (NYU, Columbia, Seoul National, UCL)
• Government organizations worldwide
• Infrastructure-intensive organizations
• Technology operators
• Startups and freelancers
• SysAdmins and DevOps professionals
