How it works

What it is

Litmus DataHub Explorer is a browser-based window into the DataHub, the NATS message broker inside every Litmus Edge device. Point it at a device, paste the device's API key, and every message on the broker starts streaming into the page.

What you can do

• Browse every subject in a live tree with per-subject message counts and rates
• See all tags at once in a sortable, filterable table with current value, type, rate and last-seen time
• Chart values live: pin up to four numeric fields and watch them plot, with a crosshair and a normalize option for mixed scales
• Inspect payloads as raw text, pretty JSON or metadata, with per-subject history
• Publish test messages to any subject, or lock the UI to read-only
• Light and dark themes following the Litmus design system

Built for the edge

It runs as a single Docker container on the Litmus Edge device itself or on any machine that can reach it. It serves HTTPS out of the box, can require a login token, and stays responsive under heavy message rates by sampling payload detail while keeping counts exact. Connection details such as Litmus Edge's authentication style and self-signed broker certificates are negotiated automatically.
