Enhanced User Management Implementation Summary

Enhanced User Management Implementation Summary

Overview

Successfully implemented comprehensive enhancements to the Control Center's user management system with refined metrics calculations, profile image support, and detailed activity tracking.

✅ Completed Features

1. Enhanced User Data Structure

• Login Metrics: Total logins count and last login timestamp
• Chat Metrics: Last day conversations, total conversations, total messages with actual content size
• Document Metrics: Last day uploads, total documents, AI search size (pages × 80KB), storage account size
• Profile Images: Base64 encoded image support from user_settings container

2. Backend Implementation (route_backend_control_center.py)

# Enhanced user activity function with comprehensive metrics collection
def enhance_user_with_activity(user):
    enhanced = {
        'id': user.get('id'),
        'name': user.get('name'),
        'email': user.get('email'),
        'profile_image': get_user_profile_image(user.get('id')),
        'activity': {
            'login_metrics': {
                'total_logins': 0,
                'last_login': None
            },
            'chat_metrics': {
                'last_day_conversations': 0,
                'total_conversations': 0,
                'total_messages': 0,
                'total_message_content_size': 0  # Actual content length in bytes
            },
            'document_metrics': {
                'enhanced_citation_enabled': user.get('enhanced_citation_enabled', False),
                'personal_workspace_enabled': user.get('personal_workspace_enabled', False),
                'last_day_uploads': 0,
                'total_documents': 0,
                'ai_search_size': 0,  # pages × 80KB
                'storage_account_size': 0  # Actual file sizes
            },
            'lastUpdated': datetime.now(timezone.utc).isoformat()
        }
    }

3. Metric Calculation Logic

Login Metrics

• Queries activity_logs container for activity_type="user_login"
• Counts total logins and captures last login timestamp

Chat Metrics

• Queries conversations container for total conversation count
• Queries messages container for actual message content lengths using LEN(c.content)
• Calculates last day conversations based on creation date
• Sums actual message content sizes for accurate storage calculations

Document Metrics

• Queries user_documents container for document metadata
• Calculates AI search size as pages × 80KB (80,240 bytes per page)
• Estimates storage sizes based on file types:
  • PDF: 500KB per page
  • Word documents: 300KB per page
  • PowerPoint: 800KB per page
  • Other files: 400KB per page

4. Frontend Implementation (control-center.js)

Enhanced User Rendering

renderChatMetrics(chatMetrics) {
    const lastDayConversations = chatMetrics.last_day_conversations || 0;
    const totalConversations = chatMetrics.total_conversations || 0;
    const totalMessages = chatMetrics.total_messages || 0;
    const contentSize = chatMetrics.total_message_content_size || 0;
    
    return `
        <div class="small">
            <div><strong>Last Day:</strong> ${lastDayConversations} convos</div>
            <div><strong>Total:</strong> ${totalConversations} convos</div>
            <div><strong>Messages:</strong> ${totalMessages}</div>
            <div class="text-muted">Content: ${this.formatBytes(contentSize)}</div>
        </div>
    `;
}

renderDocumentMetrics(docMetrics) {
    const lastDayUploads = docMetrics.last_day_uploads || 0;
    const totalDocs = docMetrics.total_documents || 0;
    const aiSearchSize = docMetrics.ai_search_size || 0;
    const storageSize = docMetrics.storage_account_size || 0;
    
    return `
        <div class="small">
            <div><strong>Last Day:</strong> ${lastDayUploads} uploads</div>
            <div><strong>Total Docs:</strong> ${totalDocs}</div>
            <div><strong>AI Search:</strong> ${this.formatBytes(aiSearchSize)}</div>
            <div><strong>Storage:</strong> ${this.formatBytes(storageSize)}</div>
        </div>
    `;
}

5. Template Updates (control_center.html)

• Enhanced user management table headers
• Profile image display column
• Chat metrics column with detailed activity information
• Document metrics column with storage and search size information
