Release Summary

Another 3 months have passed, we're already mid-way through 2024, and it's time for another Netdata release! The Netdata team has been super busy cooking up some great new features we're sure you will enjoy. Users can now dynamically configure collectors and alerts from the UI, the long-awaited Native Windows agent is almost here, AWS billing integration and so many more cool features.

In a crowded observability market, Netdata stands out with real-time monitoring and a truly unique decentralized architecture which ensures the data, always stays on-prem!

Release Highlights

Dynamic Configuration out of beta

Manage Netdata from the Dashboard:

• Alert Management: create and adjust alerts directly from any chart or the dedicated Alerts tab.
• Collectors Setup (go.d only): configure collectors for the data you need right from the Integrations section.
• Multi-Node Management: deploy configurations to multiple nodes with a single click

After fine-tuning of our Dynamic Configuration feature (DynCfg) based on extensive feedback, we have now made a GA release available to our Business and Homelab plans.

Netdata subscriptions on AWS Marketplace

AWS Customers can now manage their payments and subscriptions directly from AWS - no need for extra budget approvals or billing complexities!

• Annual Contract Listing
• Pay As You Go Subscription

Native Windows Support

Netdata's current code base can now be compiled on Windows and runs smoothly on all versions of the Windows operating system.

Currently, this feature is in the internal testing phase. We are working on packaging it and adding Windows-specific
collectors. In the next Netdata release, we will provide binary packages for Microsoft Windows.

Okta and OpenID SSO Authentication

Effortlessly manage your teams’ access with SSO through Okta or OpenID integrations. This feature ensures streamlined access
and heightened security across your systems. We are now looking into building the next step to allow you to manage
your users' Roles and Permissions!

Time Based Retention

Netdata now offers a more granular approach to data retention, allowing you to manage storage based on both time and
disk space. This update provides greater control and helps you optimize storage usage for your specific needs.

Tier	Resolution	Time Limit	Size Limit
0	high	14 days	1 GiB
1	middle	3 months	1 GiB
2	low	2 years	1 GiB

With these defaults, Netdata requires approximately 4 GiB of storage space (including metadata).

Retention Settings

You can fine-tune retention for each tier by setting either the time limit or size limit to zero. This enables various
retention strategies as shown in the table below:

Setting	Retention Behavior
Size Limit = 0, Time Limit > 0	Time-based only: data is stored for a specific duration regardless of disk usage.
Time Limit = 0, Size Limit > 0	Space-based only: data is stored until it reaches a certain amount of disk space, regardless of time.
Time Limit > 0, Size Limit > 0	Combined time and space limits: data is deleted once it reaches either the time limit or the disk space limit, whichever comes first.

Monitoring Retention Utilization

A new chart has been added to the Netdata Monitoring section of your dashboard. This chart displays the utilization
percentage for both time and space limits across all tiers, providing a clear overview of your storage usage.

Database Compression

Netdata now utilizes ZSTD compression within its database engine (dbengine), significantly reducing the storage space
required for your monitoring data. This translates to a mere 0.5 bytes per sample on disk for the high-resolution tier!

Netdata's impressive compression capabilities are the result of a powerful combination of features:

• Fixed-step database design.
• Gorilla compression (introduced in v1.45.0).
• ZSTD compression (new in v1.46.0).

ClickHouse Collector

Netdata now ships with a native ClickHouse collector,
which collects performance data from ClickHouse for connections, queries, resources, replication, IO, and data operations
(inserts, selects, merges) using HTTP requests and ClickHouse system tables.

OpenTelemetry Compatibility

All the units on our charts and metrics are now compatible with the Unified Code for Units of Measure (UCUM). This alignment ensures precision, consistency, and ease of integration across diverse systems, paving the way for more seamless observability and monitoring experiences. Stay tuned for more updates as we continue to enhance our platform!

More Notification Integrations

And as always we keep adding more integrations for notifications. You can now send your Netdata alerts from Netdata Cloud to Splunk,
VictorOps, MS Teams, and more!
