Streams & consumers

Streams

The home view lists every stream you have access to, with a quick search and key stats - message count, consumer count, subjects, storage, and retention. Select a stream to open its detail view.

The stream detail view shows:

• Stats - latest and oldest sequence, message and byte totals, publish rate, average message size, and last activity.
• Configuration - storage type, retention policy, limits, replicas, cluster, and leader.
• Health signals - badges that surface issues like DLQ activity, backlog, or stale data, with a tone (info / warning / critical).
• Tabs - Messages, Consumers, and Subjects.

Consumers

The Consumers tab lists each consumer with its health, lag, and throughput:

• Health filters - narrow to critical, warning, paused, retrying, backlog, or healthy consumers, and sort by name, pending, lag, rate, or health.
• At a glance - pending count, total lag, estimated catch-up time, delivery group, filter subjects, ack policy, and a throughput sparkline.
• Expand a consumer for detailed diagnostics: a throughput chart over a chosen time window, publisher-vs-consumer rate comparison, p50–p99 message-size percentiles, and health signals with suggested actions.

Subjects

The Subjects tab lists the subjects captured by the stream with per-subject message counts, byte sizes, and first/last timestamps, so you can see which subjects are hot and jump straight to their messages.
