nanoStream Analytics Release – April 2026

April 2026 | nanoStream Analytics API v2.34.0 · Dashboard v2.32.0

We’re excited to announce the latest update to nanoStream Analytics, bringing new visibility into Live Captions usage, a new alert type for inactive ingest streams, improved ABR quality reporting, and expanded misuse detection for MoQ streams.

Misuse detection on the Guardian Table — Now supporting MoQ

Misuse detection on the Guardian Table, which is based on IP and Playback tokens, now supports the MoQ (Media over QUIC) protocol in addition to existing protocols. This ensures that MoQ-based streams are covered alongside existing protocols in the monitoring table.

Why it matters:

As MoQ adoption grows, so does the need to monitor it for unauthorized use. Whether you are running RTMP, WebRTC, or MoQ streams, you now have consistent protection across the board without any additional configuration.

New Alert: Inactive Ingest — Detect streams that stop sending data

A stream can remain connected and continue ingesting without actually delivering any data. This silent failure is difficult to spot and can disrupt live operations just as much as a full outage. To address this, the Troubleshooting section of the dashboard now includes an Inactive Ingest alert type. It detects when a stream is still ingesting but stops sending data unexpectedly, allowing issues to be identified immediately.

When such a condition occurs, a dedicated widget visualizes a timeline of inactive ingest periods. This helps pinpoint when data flow stopped without requiring deep inspection of raw metrics.

Why it matters:

Instead of waiting for viewer complaints or manually checking stream health, you get a clear, visual record of ingest interruptions. This shortens your response time, helps you investigate root causes faster, and gives you a reliable audit trail of stream health events.

ABR Switch Reporting — Now supports up to five ABR profiles

The ABR (Adaptive Bitrate) switch metric on the Worldmap has been enhanced and now provides a breakdown across up to five ABR profiles.

Why it matters:

If you’re using ABR to deliver adaptive streams to viewers across varying network conditions, you need accurate data to understand how often quality shifts occur and at what levels. Now you can confidently use it to evaluate your stream profiles, identify quality degradation patterns by region, and optimize your ABR ladder for a better viewer experience.

Live Captions Analytics — Understand Your Usage at a Glance

You can now monitor Live Captions usage directly in the nanoStream Analytics Dashboard via the new Live Captions page ( /liveCaptions ).

This section provides four dedicated widgets:

Uptime usage over time — a timeseries view of how long captions were active
Uptime by source language — breakdown of usage per input language
Uptime by target language — breakdown of usage per output/translation language
Uptime by stream name — per-stream caption usage

All four views are also available via dedicated API routes under /api/v2/captions/usage/, making it easy to integrate caption data into your own tooling or reporting pipelines.

Why it matters:

If you use Live Captions as part of your streaming service, you can now track adoption, measure usage against costs, and make data-driven decisions about your caption infrastructure.
