Microsoft Azure SignalR
Microsoft Azure SignalR - An Overview
Azure SignalR is a fully managed service in Microsoft Azure that enables real-time communication between server-side applications and connected clients. It manages client connections and supports multiple transport protocols, making it ideal for chat applications, live dashboards, collaborative tools, and other real-time scenarios.
Applications Manager's Azure SignalR monitoring provides key metrics to track active connections, connection activity, message throughput, inbound and outbound traffic, server load, connection quota utilization, error rates, and server connection latency. Monitor your Azure SignalR service to ensure reliable and high-performance real-time communication.
