Release Summary

This release brings AI-powered monitoring intelligence and expanded platform support to all Netdata users.

Release Highlights

Model Context Protocol (MCP) Server Integration

Every Netdata Agent and Parent now functions as an MCP server, enabling AI assistants like Claude Desktop to query and analyze your infrastructure monitoring data through a built-in WebSocket interface.

What MCP Enables

AI assistants gain read-only access to your monitoring data:

• Infrastructure Discovery: Hardware specs, OS details, and streaming topology
• Metric Intelligence: Full-text search across all contexts, instances, dimensions, and labels
• System Insights: Execute functions for processes, network connections, systemd journals, and Windows events
• Alert Analysis: View real-time alerts and complete alert history
• Advanced Analytics: Complex metric queries with ML-powered anomaly detection
• Root Cause Analysis: Correlate metrics and anomaly scores to identify issues

Security First

• Sensitive functions (logs, process monitoring) require temporary API keys
• Existing Netdata permissions control all data access
• WebSocket connections need explicit configuration in AI clients

Scalable Visibility

AI assistant visibility scales with your connection point:

AI Insights: Enhanced with Natural Language Investigation

AI Insights now understands your questions. Simply ask "What went wrong yesterday at 3 PM?" and get a comprehensive report targeting your specific concern—no more manual metric correlation or dashboard hunting during incidents.

Available Reports

What's New

• Natural Language Queries: Ask questions in plain English about any timeframe or issue
• Targeted Analysis: Get reports focused on your specific problem, not generic overviews
• Alert Resolution Guidance: Coming soon—automated investigation of active alerts with fix recommendations

Privacy and Limits

• Reports are generated on-demand and immediately disposed
• Your infrastructure data is never used for AI training
• All reports share the monthly limit of 10 reports

Okta Integration: Full SCIM Group Provisioning Support

The Okta integration now supports complete SCIM group provisioning, enabling automatic synchronization of both users and groups between Okta and Netdata Cloud.

What's New

Previously limited to user provisioning, the integration now includes:

Automated Access Management

When you add or remove users from groups in Okta, these changes instantly reflect in Netdata Cloud. This enables powerful automation scenarios:

• Assign users to specific Netdata spaces based on their Okta department groups
• Grant room access automatically based on team membership
• Revoke access immediately when users leave groups

Learn how to configure SCIM group provisioning in our documentation or explore the Netdata integration in Okta's marketplace.

Automated SNMP Monitoring with Device Profiles

Netdata v2.6.0 adds SNMP profile-based collection (alpha), transforming complex SNMP monitoring into a plug-and-play experience. The profile system makes enterprise network monitoring accessible to everyone, from home labs to data centers, with the simplicity Netdata is known for.

Getting started is simple:

• Existing users: Profiles are automatically enabled and your devices will be detected and monitored with no additional configuration
• New users: Just configure SNMP credentials, and Netdata handles the rest

What's New

Extensive Device Coverage

Netdata ships with profiles for major network vendors, adapted from Datadog’s battle-tested definitions:

Native Package Support for RHEL 10 and Derivatives

Netdata now provides native packages for RHEL 10, AlmaLinux 10, and Rocky Linux 10.
These packages ensure seamless integration with corporate deployment tools, automated updates, and compliance requirements typical in enterprise environments. Whether you're running RHEL 10 in production or using AlmaLinux or Rocky Linux as alternatives, you get the same reliable, optimized Netdata experience.

Rust-Based systemd-journal Plugin for Static Builds

Release Summary

Netdata 2.3 delivers significant enhancements to monitoring reliability and scalability:

• Crash Handling & Reporting: A zero-sampling system that captures and analyzes agent crashes with complete diagnostic information, significantly improving reliability across diverse environments.
• Extreme Cardinality Protection: Automatic safeguards that maintain performance in high-scale environments with millions of time series while intelligently managing metadata retention.
• Nodes Ephemerality & Streaming Alerts: A sophisticated approach to handling node connections in distributed environments, reducing alert noise by distinguishing between permanent and ephemeral nodes.
• SNMP Service Discovery: A new system automatically finds and monitors SNMP-enabled devices on configured networks, eliminating manual configuration.

Release Highlights

Nodes Ephemerality & Streaming Alerts

Netdata 2.3 implements a more sophisticated approach to handling node connections in distributed environments. We now define ephemeral nodes as "nodes that are expected to disconnect without raising alerts", enabling smarter monitoring of dynamic infrastructure.

Learn more about managing ephemeral nodes.

Extreme Cardinality Protection

Netdata 2.3 introduces automatic protection against extreme cardinality issues when combining high-dimensional metrics with long retention periods. This system:

This protection maintains Netdata's performance even in high-scale environments with millions of time series, while still allowing unlimited cardinality for high-resolution data. Learn more about configuring this feature.

Crash Handling & Reporting

We've implemented a powerful, zero-sampling crash monitoring system that captures and analyzes agent restarts and crashes with complete diagnostic information. This solution leverages systemd's journal for flexible, scalable event tracking without additional licensing costs. With anonymous telemetry enabled, this system helps us identify critical issues across diverse environments, significantly improving Netdata's reliability for all users. Read more about our approach in this blog post.

SNMP Discovery

Netdata 2.3 adds an SNMP service discovery system that automatically finds and monitors SNMP-enabled devices on your networks.
