The Ops Dashboard is the landing page of the Operations Console (/ops). It provides a real-time view of the event-sourcing pipeline — ingestion rates, processing throughput, latency percentiles, queue health, and top errors — all in a single screen.
Metrics Overview
The top of the dashboard displays six key metrics, each showing the current rate and a secondary stat (peak, total, or count):
| Metric | What it measures | Secondary stat |
|---|
| Staged/s | Ingestion rate — commands entering the queue | Peak rate |
| Completed/s | Processing throughput — commands fully processed | Total completed |
| Failed/s | Failure rate — commands that errored | Total failed |
| Blocked | Groups stuck due to errors | Number of error groups |
| DLQ | Items in the Dead Letter Queue | Redis memory usage |
| P50 / P99 | End-to-end processing latency | Peak latency |
Metrics marked in red indicate an active problem — non-zero failure rates or blocked groups. Orange indicates a warning state, such as items in the DLQ.
Active Operations
When a projection replay is running or pipelines are paused, a banner appears below the metrics showing:
- Replay status with the current projection name and a link to the detailed progress view
- Paused pipelines listed as orange badges
Throughput Chart
A time-series chart tracks throughput over time, showing staged, completed, and failed rates. Use this to identify processing backlogs (staged >> completed) or failure spikes.
Pipeline Tree
The pipeline tree shows the hierarchical structure of all processing pipelines. Each node represents a pipeline stage.
Operators with ops:manage permission can pause and unpause individual pipeline stages directly from the tree. Pausing a stage prevents new jobs from being consumed while allowing in-flight jobs to complete.
Top Errors
The bottom of the dashboard lists the top error patterns across all queues, showing:
- Count — how many jobs hit this error
- Error message — normalized and deduplicated
- Pipeline — which pipeline stage produced the error
This gives a quick signal on whether errors are concentrated in a single pipeline or scattered across the system.
Real-Time Updates
The dashboard uses Server-Sent Events (SSE) for real-time metric streaming. A connection status indicator in the header shows:
- Connected (green) — live SSE connection active
- Polling (yellow) — SSE unavailable, falling back to 5-second polling
- Disconnected (red) — no connection
Both modes deliver the same data; SSE simply provides lower-latency updates.
Replay History
A compact section at the bottom shows the latest projection replay run with its status, duration, and description. Click it to navigate to the full replay detail view.
