# Status Dashboard — Retired

> **Revision** — Retired 2026-04-19 (task #205). The embedded HTTP Status Dashboard hosted inside the v1 LmxOpcUa service (`Dashboard:Port 8081`) has been **superseded by the Admin UI** introduced in OtOpcUa v2. The requirements formerly numbered DASH-001 through DASH-009 no longer apply.

## What replaces it

Operator surface is now the **OtOpcUa Admin** Blazor Server web app:

- Canonical design doc: `docs/v2/admin-ui.md`
- High-level operator surface requirement: [HLR-015](HighLevelReqs.md#hlr-015-admin-ui-operator-surface)
- Service-host requirements for the Admin process: [ServiceHostReqs.md → ADM-*](ServiceHostReqs.md#otopcua-admin---service-host-requirements-adm-)
- Cross-cluster metrics endpoint: `/metrics` on the Admin app — see [HLR-017](HighLevelReqs.md#hlr-017-prometheus-metrics).
- Audit log: see [HLR-016](HighLevelReqs.md#hlr-016-audit-logging) and `AuditLogService`.

## Mapping from retired DASH-* requirements to today's surface

| Retired requirement | Replacement |
|---------------------|-------------|
| DASH-001 Embedded HTTP listener | Admin UI (Blazor Server) hosted in the `OtOpcUa.Admin` process. |
| DASH-002 Connection panel | Admin UI cluster-node view (live via SignalR) shows per-driver connection state. |
| DASH-003 Health panel | Admin UI renders `DriverHealth` + Polly circuit state per driver instance; cluster-level rollup on the cluster dashboard. |
| DASH-004 Subscriptions panel | Prometheus gauges (session count, monitored-item count, driver-subscription count) exposed via `/metrics`. |
| DASH-005 Operations table | Capability-call duration histograms + counts exposed via `/metrics`; Admin UI renders latency summaries per `DriverInstanceId`. |
| DASH-006 Footer (last-updated + version) | Admin UI footer; version stamped from the assembly version of the Admin app. |
| DASH-007 Auto-refresh | Admin UI uses SignalR push for live updates — no meta-refresh. |
| DASH-008 JSON status API | Prometheus `/metrics` endpoint is the programmatic surface. |
| DASH-009 Galaxy info panel | Admin UI Galaxy-driver-instance detail view (driver config, last discovery time, Galaxy DB connection state, MXAccess pipe health). |

A formal requirements-level doc for the Admin UI (AdminUiReqs.md) is not yet written — the design doc at `docs/v2/admin-ui.md` serves as the authoritative reference until formal cert-compliance requirements are needed.
