Analytics Dashboard

EasyStream includes a comprehensive analytics system for creators to track performance, audience insights, and growth metrics.

Features

• 📊 Channel Overview - Key metrics at a glance (views, watch time, subscribers, engagement)
• 📈 Time Series Charts - Track growth over time with customizable date ranges
• 🎯 Traffic Sources - Understand where your viewers come from
• 👥 Audience Demographics - Geographic, device, age, and gender breakdowns
• 🎬 Top Videos - Identify your best-performing content
• 📉 Audience Retention - Minute-by-minute drop-off analysis
• ⚡ Real-time Stats - Live viewer counts and recent activity
• 🤖 Automatic Tracking - No manual instrumentation required

Setup

1. Database Migration

Run the migration to create analytics tables:

docker-compose exec db mysql -u easystream -peasystream easystream < __install/migrations/004_add_analytics_system.sql

This creates:

• db_video_analytics - Detailed event tracking
• db_channel_analytics_daily - Daily aggregated summaries
• db_traffic_sources - Traffic source tracking
• db_audience_retention - Minute-by-minute retention
• db_audience_demographics - Demographic breakdowns
• db_realtime_stats - Cached real-time metrics

2. Add Tracking Script to Video Player

Include the analytics tracker on your video watch page:

<script src="/f_scripts/fe/js/video-analytics.js"></script>

The tracker will auto-initialize and begin tracking:

• Video views
• Watch time
• Completion rate
• Audience retention
• Traffic sources

3. Set Up Daily Aggregation Cron

Add a cron job to aggregate daily stats:

# Run every day at 1 AM
0 1 * * * cd /srv/easystream && php app_scripts/cron/aggregate_analytics.php >> /var/log/analytics-aggregation.log 2>&1

This consolidates raw analytics data into daily summaries for fast dashboard loading.

Tracking Implementation

Automatic Tracking

The VideoAnalyticsTracker JavaScript class handles automatic tracking:

// Auto-initializes on video watch pages
const tracker = new VideoAnalyticsTracker(videoId, {
    playerElement: document.querySelector('video'),
    trackingInterval: 10000 // Update every 10 seconds
});

What gets tracked:

• View on first play
• Watch time every 10 seconds
• Retention (minute-by-minute)
• Completion when video ends
• Traffic source detection
• Final progress on page unload

Manual Tracking

Track custom events:

await fetch('/api/analytics.php?action=track', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
        video_id: 123,
        event_type: 'share',
        source_type: 'social',
        source_detail: 'twitter'
    })
});

Backend Tracking

Track events from PHP:

require_once 'f_core/f_classes/class.analytics.php';
$analytics = new VAnalytics();

// Track a view
$analytics->trackEvent($video_id, 'view', [
    'usr_id' => $user_id,
    'watch_duration' => 180,
    'completion_percentage' => 75.5
]);

// Track traffic source
$analytics->trackTrafficSource($video_id, $channel_owner_id, 'search', 'google');

// Track retention
$analytics->trackRetention($video_id, $minute);

Advanced Analytics

Custom Metrics

Add custom tracking for specific features:

// Track custom interaction
fetch('/api/analytics.php?action=track', {
    method: 'POST',
    body: JSON.stringify({
        video_id: videoId,
        event_type: 'custom',
        custom_metric: 'chapter_viewed',
        custom_value: chapterNumber
    })
});

A/B Testing

Track experiment variants:

$analytics->trackEvent($video_id, 'view', [
    'experiment_id' => 'thumbnail_test',
    'variant' => 'A'
]);

Revenue Tracking

Integrate with monetization:

$sql = "UPDATE db_channel_analytics_daily 
        SET revenue_last_24h = ? 
        WHERE usr_id = ? AND date = CURDATE()";

Troubleshooting

Dashboard shows no data

1. Check analytics tracking is enabled in video player
2. Verify JavaScript console for errors
3. Check database tables exist
4. Run aggregation manually: php app_scripts/cron/aggregate_analytics.php

Retention graph empty

1. Ensure video tracker is loaded on watch page
2. Check db_audience_retention table has data
3. Verify video ID is correct

Real-time stats not updating

1. Check db_realtime_stats table
2. Ensure views are being tracked
3. Verify cache expiry (5 minutes)
