Data Health

Data Health shows how well the data flowing through your Unified Namespace matches the structure and quality you defined in Contextualize. It surfaces data-quality metrics, deviations from the expected schema, and performance indicators for your governed streams, so you can confirm that downstream consumers receive trustworthy, well-shaped data.

The view opens on two tabs — Data Health and Deviations — and a timeframe selector, such as Last Week, that scopes every metric on the page.

The Data Health overview with totals and a per-broker breakdown

Data Health in Total

The Data Health in Total panel summarizes the quality of all traffic across your connected brokers for the selected timeframe. Each metric shows its share, the number of messages behind it, and the trend over the timeframe.

Metric	Description
Total Traffic	All messages observed across your connected brokers in the selected timeframe.
Governed Traffic	The share of traffic that is modeled and managed in your Unified Namespace.
Ungoverned Traffic	The share of traffic that is not part of the namespace. Use Discovery in Contextualize to bring it under governance.
Healthy Traffic	Governed traffic that conforms to the expected data types and structure.
Deviating Traffic	Governed traffic that does not match the expected structure — a deviation from the namespace declaration.
Ignored Traffic	Traffic on topics you have explicitly chosen to ignore.

Metric

Description

Total Traffic

All messages observed across your connected brokers in the selected timeframe.

Governed Traffic

The share of traffic that is modeled and managed in your Unified Namespace.

Ungoverned Traffic

The share of traffic that is not part of the namespace. Use Discovery in Contextualize to bring it under governance.

Healthy Traffic

Governed traffic that conforms to the expected data types and structure.

Deviating Traffic

Governed traffic that does not match the expected structure — a deviation from the namespace declaration.

Ignored Traffic

Traffic on topics you have explicitly chosen to ignore.

Together these describe the full picture of your traffic: total traffic splits into governed and ungoverned, and governed traffic in turn splits into healthy, deviating, and ignored. A high share of healthy, governed traffic means downstream consumers can rely on the data.

Data Health per Broker

The Data Health per Broker panel breaks the same picture down for each connected broker, so you can pinpoint where deviations originate. Use the search field to find a broker by name or ID.

Column Description

Column	Description
Name	The name of the broker — for example, `HQ Broker`.
Type	The broker type, such as Enterprise.
Healthy	The number and share of the broker’s traffic that is healthy.
Deviating	The number and share of the broker’s traffic that is deviating.
Ratio	A visual healthy-to-deviating ratio for the broker at a glance.
Deviations over Timeframe	A trend of the broker’s deviations across the selected timeframe.
Actions	Drill into the broker for a closer look at its data health.
