SignalR Service

Home

Namespace: Microsoft.Azure.IIoT.Services.OpcUa.Events

Overview

The SignalR event service forwards …

  • Registry update events (from ServiceBus Topics)
  • Discovery Progress (from ServiceBus Topics)
  • telemetry samples from the secondary Telemetry EventHub

over SignalR to clients and thus provides a reactive UX experience.

The secondary Telemetry EventHub receives processed and decoded edge telemetry messages from the OPC Publisher module (PubSub). This is the same EventHub that Azure Time Series Insights (TSI) can connect to for historian query capability.
