Analytics Graph Improvements - Summary

Problem Identified

The analytics graph displayed no data visually, showing an empty chart with no bars or information.

Root Cause

• UMAMI_WEBSITE_ID is empty in the .env file
• Backend was returning empty data arrays {} and [] when Umami connection failed
• No visual feedback to indicate why analytics were not working
• Limited logging made troubleshooting difficult

Solutions Implemented

1. Enhanced Frontend Error Handling

File: frontend/src/pages/admin/AnalyticsAdminPage.tsx

Changes:

• Added state variables:

  • hasData: Tracks whether any analytics data was received
  • errorMessage: Stores user-friendly error messages

• Data validation:

  • Checks if stats contain actual values (pageviews > 0, visitors > 0)
  • Validates pageviews array has non-zero values
  • Verifies metrics arrays have data

• Visual improvements:

  • Orange warning card when no data is available with:
    • Clear error message in Czech
    • List of possible causes
    • Step-by-step troubleshooting instructions
    • "Reload page" button for retry
  • Empty state in graph area when no pageviews exist
  • Friendly icon and message: "Žádná data pro zobrazení"

2. Enhanced Backend Logging

Files:

• internal/controllers/umami_controller.go
• internal/services/umami_service.go

Changes:

• Detailed logging at every step:

  // Before: No logging
  // After: 
  logger.Info("UMAMI_WEBSITE_ID is empty, attempting to auto-detect...")
  logger.Info("Attempting to find Umami website by domain: %s", host)
  logger.Info("Found default Umami website: ID=%s, Name=%s, Domain=%s", ...)
  logger.Info("Successfully fetched Umami stats for websiteID=%s (days=%d)", ...)
  

• Better error messages:

  • Shows which configuration values are missing
  • Displays URLs being attempted
  • Logs authentication success/failure with timestamps
  • Shows website detection process step-by-step

• Improved resolveWebsiteID:

  • Logs when using cached ID
  • Logs when attempting auto-detection
  • Logs domain matching attempts
  • Logs fallback to first available website

3. Graceful Fallback Behavior

• API endpoints return empty objects/arrays instead of errors
• Frontend handles empty data without crashing
• Clear user feedback instead of silent failures

User Experience Improvements

Before:

• Empty graph with no explanation
• No indication of what's wrong
• Difficult to diagnose issues
• Required checking backend logs

After:

• If configured correctly:

  • Statistics display normally
  • Graph shows pageview data
  • All metrics visible

• If not configured:

  • Orange warning banner explains the issue
  • Lists possible causes
  • Provides clear troubleshooting steps
  • Reload button for easy retry

• If no traffic yet:

  • Empty state with friendly message
  • Clear indication this is expected
  • No alarming error messages

Technical Details

Auto-Detection Flow:

1. Check if UMAMI_WEBSITE_ID is set → Use it
2. Try to match by FRONTEND_BASE_URL domain
3. Fall back to first available website in Umami
4. Cache the detected ID in memory
5. Log each step for transparency

Error Detection Logic:

const hasAnyStats = statsResponse.data && (
  (statsResponse.data.pageviews?.value && statsResponse.data.pageviews.value > 0) ||
  (statsResponse.data.visitors?.value && statsResponse.data.visitors.value > 0)
);

const hasPageviews = pageviewsDataArray.length > 0 && 
  pageviewsDataArray.some(d => d.value > 0);

const hasMetrics = pages.data?.length > 0 || countries.data?.length > 0;

setHasData(hasAnyStats || hasPageviews || hasMetrics);

Testing

To verify the fix works:

1. Restart backend server
2. Open /admin/analytika
3. Check for:
   • Orange warning if not configured (expected)
   • Graph with data if configured
   • Clear error messages instead of blank page

To generate test data:

1. Visit your website multiple times
2. Navigate between pages
3. Wait 2-5 minutes
4. Refresh analytics page
5. Data should appear

Files Modified

1. frontend/src/pages/admin/AnalyticsAdminPage.tsx

   • Added error state management
   • Enhanced visual feedback
   • Better empty states

2. internal/controllers/umami_controller.go

   • Enhanced logging throughout
   • Better error messages
   • Improved website ID resolution

3. internal/services/umami_service.go

   • Added logging to authentication
   • Better website detection logs
   • Improved error messages

4. Documentation (new):

   • ANALYTICS_GRAPH_FIX.md - Detailed troubleshooting guide
   • ANALYTICS_TEST_INSTRUCTIONS.md - Step-by-step testing guide
   • ANALYTICS_IMPROVEMENTS_SUMMARY.md - This file

Configuration Reference

Required in .env:

UMAMI_URL=https://umami.tdvorak.dev          # ✓ Set
UMAMI_USERNAME=admin                          # ✓ Set
UMAMI_PASSWORD=eevRQ6h3G@!c#y4A1T            # ✓ Set
UMAMI_WEBSITE_ID=                             # Empty (will auto-detect)

Benefits

1. Better User Experience: Clear feedback instead of confusion
2. Easier Troubleshooting: Logs show exactly what's happening
3. Self-Healing: Auto-detects website ID when possible
4. Production Ready: Graceful handling of all failure scenarios
5. Maintainable: Clear code with good error messages

Next Steps

1. Restart backend to apply changes
2. Test the analytics page to verify it works
3. Monitor logs for any connection issues
4. Create Umami website if none exists
5. Optional: Set UMAMI_WEBSITE_ID in .env once detected

Monitoring

Watch these log messages:

• ✓ Successfully authenticated with Umami
• ✓ Found default Umami website: ID=...
• ✓ Successfully fetched Umami stats
• ✗ No Umami websites found → Create website
• ✗ Authentication failed → Check credentials
• ✗ Failed to resolve Umami website ID → Check connection

Support

If issues persist:

1. Check backend logs for errors
2. Verify Umami is accessible at configured URL
3. Ensure website exists in Umami dashboard
4. Review documentation in ANALYTICS_GRAPH_FIX.md
