## Next Automatic Scrape

**Next Run**: Tomorrow at 9:00 AM UTC (2026-01-25 09:00:00 UTC)

## Manual Testing

### Option 1: Wait for Cron Trigger
The scraper will automatically run daily at 9:00 AM UTC.

### Option 2: Test Locally
```bash
# Terminal 1: Start dev server
npm run dev

# Terminal 2: Trigger scraper manually
curl "http://localhost:8793/__scheduled?cron=0+9+*+*+*"
```

### Option 3: Monitor Logs
```bash
# Watch production logs in real-time
npx wrangler tail

# Wait for next cron trigger to see output
```

## Expected Log Output

When the scraper runs (locally or in production), you should see:

```
[Scraper] Starting VPSBenchmarks.com scrape with Browser Rendering API
[Scraper] Fetching rendered HTML from vpsbenchmarks.com
[Scraper] Rendered HTML length: XXXXX
[Scraper] Extracted X benchmarks from HTML
[Scraper] Found X benchmark entries
[DB] Inserted/Updated: Provider PlanName
[Scraper] Completed in XXXms: X inserted, X skipped, X errors
```

## Verification Checklist

- [x] Code deployed successfully
- [x] All bindings configured (DB, BROWSER, AI)
- [x] Health check endpoint responding
- [x] Cron trigger scheduled
- [ ] First scrape run (waiting for next cron or manual test)
- [ ] Benchmarks extracted from vpsbenchmarks.com
- [ ] New records inserted into D1 database

## Database Verification

After the first scrape run, verify data:

```bash
# Check total benchmark count
npx wrangler d1 execute cloud-instances-db --command="SELECT COUNT(*) as total FROM vps_benchmarks"

# View latest benchmarks
npx wrangler d1 execute cloud-instances-db --command="SELECT provider_name, plan_name, geekbench_single, geekbench_multi, created_at FROM vps_benchmarks ORDER BY created_at DESC LIMIT 10"
```

## Browser Rendering API Usage

### Free Tier Limits
- **Quota**: 10 minutes per day
- **Current Usage**: 0 minutes (first run pending)
- **Estimated per Run**: < 1 minute
- **Daily Capacity**: ~10 runs (only 1 scheduled)

### Monitor Usage
Check Cloudflare dashboard for Browser Rendering API usage metrics.

## Troubleshooting

### If No Benchmarks Found

1. **Check Logs**
   ```bash
   npx wrangler tail
   ```

2. **Inspect Rendered HTML**
   - Look for "Rendered HTML length" in logs
   - If length is very small (< 10KB), page may not be loading
   - If length is large but no data extracted, selectors may need adjustment

3. **Test Locally**
   - Run `npm run dev`
   - Trigger manually with curl
   - Debug with detailed logs

4. **Update Selectors**
   - Visit https://www.vpsbenchmarks.com/
   - Inspect actual HTML structure
   - Update CSS selectors in `scrapeBenchmarksWithScrapeAPI()`
   - Adjust parsing patterns in `extractBenchmarksFromHTML()`

### If Browser Rendering API Errors

1. **Check Quota**
   - Verify not exceeding 10 minutes/day
   - Check Cloudflare dashboard

2. **Check Network**
   - Ensure Browser Rendering API is accessible
   - Check for any Cloudflare service issues

3. **Adjust Timeout**
   - Current: 30 seconds
   - Increase if pages load slowly
   - Decrease to fail faster if needed

### If Database Errors

1. **Verify Schema**
   ```bash
   npx wrangler d1 execute cloud-instances-db --command="PRAGMA table_info(vps_benchmarks)"
   ```

2. **Check Unique Constraint**
   ```bash
   npx wrangler d1 execute cloud-instances-db --command="SELECT * FROM sqlite_master WHERE type='index' AND tbl_name='vps_benchmarks'"
   ```

3. **Test Insertion**
   - Check logs for specific SQL errors
   - Verify field types match schema
   - Ensure no NULL in NOT NULL columns

## Performance Monitoring

### Key Metrics

1. **Scraper Execution Time**
   - Target: < 60 seconds per run
   - Check "Completed in XXms" log message

2. **Benchmarks Found**
   - Current database: 269 records
   - Expected: Gradual growth from daily scrapes
   - If consistently 0, parsing logic needs adjustment

3. **Error Rate**
   - Parse errors: Structure changes on source site
   - API errors: Quota or connectivity issues
   - DB errors: Schema mismatches

4. **Browser Rendering Usage**
   - Free tier: 10 min/day
   - Expected: < 1 min/day
   - Monitor Cloudflare dashboard

## Success Criteria

✅ Deployment successful
✅ All bindings configured
✅ Cron trigger active
⏳ First scrape pending (manual test or wait for cron)
⏳ Data extraction verified
⏳ Database updated with new records

## Next Steps

1. **Wait for Next Cron** (2026-01-25 09:00 UTC)
2. **Monitor Logs** (`npx wrangler tail`)
3. **Verify Database** (check for new records)
4. **Adjust if Needed** (update selectors based on actual results)

```bash
# 1. Checkout previous version
git checkout <previous-commit>

# 2. Redeploy
npm run deploy

# 3. Verify
