Both bugs surfaced only on split-role deployments (the MAIN cluster's
admin-only nodes), where the AdminUI runs without the driver role.
- Test Connect returned "No probe registered" for every driver: the
IDriverProbe set was registered only under the driver role, but the
admin-operations singleton that consumes it is pinned to admin. Extract
AddOtOpcUaDriverProbes() (idempotent via TryAddEnumerable) and call it
in the hasAdmin path too.
- Live driver-status/alerts/script-log panels showed "SignalR error:
Connection refused": these Blazor Server components opened a HubConnection
to their own hub via the browser's public URL, which server-side code
can't reach behind Traefik (host :9200 -> container :9000). Read the
in-process source directly instead -- DriverStatus via
IDriverStatusSnapshotStore.SnapshotChanged, Alerts/ScriptLog via a new
IInProcessBroadcaster<T>. Fleet status was unaffected (reads DB/ActorSystem).
Adds unit tests for probe registration, the snapshot-store event, and the
broadcaster.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
Final F15 batch wires up the SignalR-backed live pages, ports the bulk
equipment importer, and progressively enhances the Script source editor
with Monaco.
Message contracts:
- Commons.Messages.Alerts.AlarmTransitionEvent — fires on every alarm
state transition; published on the `alerts` DPS topic by future
ScriptedAlarmActor (F9) emits.
- Commons.Messages.Logging.ScriptLogEntry — one log line emitted by a
hosted script; published on the `script-logs` DPS topic by future
VirtualTagActor (F8) + ScriptedAlarmActor (F9) emits.
(Folder named "Logging" to dodge .gitignore's "logs/" rule.)
SignalR plumbing:
- AlertHub gains MethodName + bridge actor (AlertSignalRBridge)
- ScriptLogHub introduced; ScriptLogSignalRBridge follows the same
DPS-subscribe → IHubContext fan-out pattern as FleetStatusSignalRBridge
- WithOtOpcUaSignalRBridges now spawns all three bridges
- MapOtOpcUaHubs maps /hubs/script-log alongside the existing hubs
Pages:
- /alerts live alarm tail, 200-row capacity
- /script-log live script-log tail with level + script
filter, 500-row capacity
- /clusters/{id}/equipment/import — CSV bulk Equipment add with preview
(Name/MachineCode/UnsLineId/Driver +
optional ZTag/SAPID/Manufacturer/Model;
skips rows whose MachineCode already
exists in the fleet)
- ScriptEdit progressively enhanced with Monaco editor via JSInterop —
the textarea remains Blazor's source of truth and Monaco syncs into it
on every keystroke so @bind keeps working; falls back gracefully if
the CDN is unreachable.
MainLayout nav gains a "Live" section (Deployments, Alerts, Alarms
historian) and a "Scripts" link under Scripting. ClusterEquipment
surfaces the new Import CSV button.
Tally: F15 ships ~42 razor pages + 3 SignalR hubs + 3 bridge actors.
Microsoft.AspNetCore.SignalR.Client added (was already in central PM).
All 104 v2 tests remain green.
New per-admin-node actor that subscribes to the fleet-status DistributedPubSub
topic + forwards every FleetStatusChanged snapshot to all SignalR clients
connected to FleetStatusHub via IHubContext.
Wired via WithOtOpcUaSignalRBridges (new AkkaConfigurationBuilder extension in
AdminUI.Hubs) — Program.cs calls it inside the if(hasAdmin) block alongside
WithOtOpcUaControlPlaneSingletons.
Per-node subscription rather than cluster-singleton: every admin node forwards
its own snapshots to its own connected clients. Simpler than singleton
coordination + acceptable because the messages are small and SignalR fan-out
is per-node anyway.
