Implement data-driven optimization using actual server metrics instead of thresholds:
NEW FEATURES:
- lib/php-analytics.sh: Analytics engine for domain profiling
• analyze_memory_errors_from_logs: Parse error logs for memory exhaustion
• analyze_process_memory_usage: Measure actual PHP process memory via ps
• get_peak_concurrent_detailed: Extract peak concurrent requests from access logs
• detect_memory_leak_pattern: Identify domains with memory leak issues
• build_domain_profile: Complete profile with all real usage data
• Intelligent recommendations based on ACTUAL peak memory, traffic, and leak patterns
- modules/performance/php-domain-analyzer.sh: Pre-analysis script
• Scans all domains and builds comprehensive profiles
• Stores profiles in /tmp/php-domain-profiles/ for use by optimizer
• Shows summary with top memory users, traffic patterns, and potential leaks
• Displays analysis in real-time with progress indicators
- php-optimizer.sh: Profile-based optimization levels
• Option 0: Run pre-analysis to collect real usage data
• Levels 1-5: Now use profile-based recommendations (fallback to traffic-based if no profiles)
• Shows real usage data from profiles when optimizations applied
• Memory recommendations: peak_memory_seen + 20% buffer
• Max children: peak_concurrent_requests + 30% safety margin
• Max requests: 250 for leak-prone domains, 500 for normal domains
ARCHITECTURE:
- Profile format (pipe-delimited): domain|username|peak_concurrent|avg_concurrent|
total_hits|min_mem|max_mem|avg_mem|proc_count|mem_exhausted|peak_mem_seen|
leak_type|current_memory_limit|current_max_children
- Profiles cached in /tmp/php-domain-profiles/ (24 hour TTL)
- All 5 optimization levels now profile-aware
- Seamless fallback to traffic-based method if no profiles exist
CONVERSION COMPLETED:
- Level 1: Optimizes pm.max_children only (profile-aware)
- Level 2: pm.max_children + memory_limit (profile-aware)
- Level 3: All of above + pm.max_requests for leak prevention (profile-aware)
- Level 4: OPcache optimization (unchanged)
- Level 5: Complete optimization with all settings (NOW PROFILE-AWARE - FIXED)
All levels now enumeraate users/domains directly and use profile recommendations
when available, with intelligent fallback to the original traffic-based method.
