Llamachant.ExpressApp.Monitoring.Blazor 25.2.7.2

Llamachant.ExpressApp.Monitoring.Blazor

Part of the Llamachant Framework - a set of reusable modules for DevExpress eXpressApp Framework (XAF) applications.

Overview

Llamachant.ExpressApp.Monitoring.Blazor provides real-time user session monitoring for XAF Blazor applications, giving administrators visibility into active users, session status, and server diagnostics.

Key Features

• Session Monitoring - Track active user sessions with real-time status (Active, Idle, Disconnected), login time, session duration, and idle time
• Connection Details - View IP address, browser info, connection count, and heartbeat status per user
• Activity Tracking - Monitor current page, page views, action count, and per-user activity timelines
• Recent Actions - View a global action history showing recent actions across all users
• Server Diagnostics - Access server memory usage, GC memory, active session count, and uptime
• Session Termination - Administrators can force-terminate user sessions directly from the Active Users view
• Real-Time Updates - Debounced event system automatically refreshes the Active Users view when sessions change
• Circuit-Aware Cleanup - Automatic subscription and resource cleanup when Blazor circuits close

Setup

Register the module in your application builder:

builder.Modules
    .AddLlamachantFrameworkMonitoringBlazorModule(options =>
    {
        options.ShowSessionInfo = true;         // Session status, login time, duration, idle time
        options.ShowConnectionInfo = true;      // IP address, browser info, connection count, heartbeat
        options.ShowActivityInfo = true;        // Current page, page views, action count, timeline
        options.ShowServerInfo = true;          // Server memory, GC memory, session count, uptime
        options.MaxActivityCount = 20;          // Max timeline entries per user session
        options.MaxGlobalActivityCount = 100;   // Max entries in global recent action history
        options.AllowTerminatingSessions = true; // Allow admins to force-terminate sessions
        options.AllowViewingRecentActions = true; // Allow viewing the recent actions popup
    });

All options have sensible defaults, so you can also register with no configuration:

builder.Modules
    .AddLlamachantFrameworkMonitoringBlazorModule();

Architecture

The module registers the following services:

How It Works

1. User logs in and ActiveUserService.UserConnected() registers the session
2. MonitoredCircuitHandlerProxy captures circuit lifecycle events (connect, disconnect, reconnect)
3. NavigationTracker monitors page navigation changes
4. ActiveUsersActionTrackingController records action execution across all controllers
5. The Active Users ListView displays session data via non-persistent objects
6. Real-time updates are delivered through debounced circuit-aware subscriptions

Requirements

• .NET 8.0 and higher
• DevExpress XAF v25.2 or later
