- Add calculate_performance_score() function that counts CRITICAL/WARNING issues
- Calculate A-F grade based on severity: A (90+), B (80-89), C (70-79), D (60-69), F (<60)
- Score formula: 100 - (critical_count * 10) - (warning_count * 2), bounded 0-100
- Integrate performance score display at top of diagnostic report with box formatting
- Add save_report_to_file() function to save full report to /tmp with timestamp
- Add interactive prompt after report generation to save to file (y/n)

ISSUE:
RCE (Remote Code Execution) attacks were being DETECTED and LOGGED
but NOT BLOCKED, allowing the attacks to proceed even with Score:100.
ROOT CAUSE:
The ET-based blocking only triggered if:
1. Both record_request AND detect_rate_anomaly functions exist AND
2. Combined score >= 90
If either function failed or didn't exist, RCE wasn't immediately blocked.
SOLUTION:
Add explicit, immediate blocking for RCE attacks:
- Detect RCE|WEBSHELL|ECOMMERCE_EXPLOIT in attack types
- Block IMMEDIATELY regardless of score calculation
- Don't wait for rate anomaly detection
- Log as INSTANT_BLOCK_RCE for clear visibility
AFFECTED ATTACKS (Now immediately blocked):
- RCE (Remote Code Execution)
- WEBSHELL (Web shell uploads/access)
- ECOMMERCE_EXPLOIT (Commerce site exploits)
IMPACT:
- 0-second blocking for RCE attempts (previously delayed)
- Prevents exploitation of PHP shells and upload endpoints
- Eliminates time window for attackers to interact with shells
Applied to both live-attack-monitor.sh and live-attack-monitor-v2.sh

The warning "[WARNING] Detected CSF (inactive)" is misleading because:
- CSF detection can't properly distinguish between truly inactive and
situations where the lfd process temporarily isn't running
- This creates false alarms and confusion for users
- The status is informational, not actionable
CHANGE:
- When CSF is detected but lfd process not running: change from WARNING to INFO
- Cleaner output without false negatives
- Only flag real errors that require user action
This improves the signal-to-noise ratio in the system detection output.

ISSUE:
Batch analyzer only flagged domains for optimization when recommended < current
(only reductions). Domains needing INCREASES were marked "OK" even with:
• Critical traffic (73 concurrent requests)
• Severely undersized configuration (5 max_children)
EXAMPLE:
Current: 5, Recommended: 20, Traffic: 73 concurrent
Old: Status "OK" (no change detected)
New: Status "NEEDS OPTIMIZATION" (recognized undersizing)
FIX:
- Flag optimization when recommended != current
- ONLY if change is meaningful:
• Has significant traffic (>= 5 concurrent requests) OR
• Offers significant memory savings (>= 20% reduction)
RATIONALE:
- Domains with critical traffic should be optimized even if it increases max_children
- Undersized configurations are just as problematic as oversized ones
- Users need to see both increases and decreases in optimization recommendations
This ensures the batch analyzer surfaces all actionable optimization opportunities.
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
ROOT CAUSE:
The batch analyzer calls calculate_optimal_php_settings() which relies on
calculate_max_children_memory_based(). When no active PHP-FPM processes exist
(common in ondemand mode with sparse traffic), both functions returned 0.
IMPACT:
- Recommending pm.max_children: 0 (completely invalid, breaks PHP-FPM)
- Causes silent failures in optimization reports
- Especially problematic with ondemand PM mode + low traffic domains
FIXES:
1. calculate_max_children_memory_based():
• When no processes detected: return 20 instead of 0
• When invalid parameters: return 20 instead of 0
2. calculate_optimal_php_settings():
• Added CRITICAL safety check: if final_max_children <= 0, use 20
• Ensures output is always safe regardless of calculation errors
DEFAULTS:
- Memory-based: 20 (safe minimum when no process data available)
- Traffic-based: Uses actual peak concurrent if available
- Safety guardrail: 20 minimum in all code paths
This prevents invalid recommendations and ensures batch analyzer always
provides sensible, actionable optimization guidance.
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
CRITICAL BUG FIX:
When peak_concurrent or peak_mem_seen = 0 (no traffic/memory data detected),
the recommendation functions were:
1. Calling wrong fallback functions (calculate_optimal_max_requests for max_children)
2. Returning 0 or invalid values instead of safe defaults
FIXES:
- get_max_children_recommendation():
• When peak_concurrent = 0: return safe minimum of 5
• Fixed incorrect fallback to calculate_optimal_max_requests
• Added proper traffic-based fallback calculation
- get_memory_limit_recommendation():
• When peak_mem_seen = 0: return safe default of 128M
• Ensures memory limits are never recommended as 0 or invalid
IMPACT:
- Prevents recommending pm.max_children: 0 (which is invalid)
- Ensures all recommendations have sensible minimums
- Improves analyzer robustness when domains have no recent logs
ROOT CAUSE:
Incomplete handling of zero-value cases during profile analysis.
Safe defaults are essential when usage data is sparse.
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
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.

CHANGES:
1. SOURCE IMPROVED CALCULATOR LIBRARY
- Added source statement for php-calculator-improved.sh
- Makes all improved calculation functions available
2. UPDATE DOMAIN ANALYSIS DISPLAY
- Now shows BOTH improved and legacy algorithm results
- Displays side-by-side comparison of recommendations
- Shows memory savings/safety improvements
- Color-coded to show which is recommended
3. ENHANCED OPTIMIZATION SECTION
- Updated to use improved_max_children instead of legacy
- Applies traffic-aware recommendations immediately
- Shows detailed reasoning for recommendations
4. IMPROVED CHECK_SERVER_MEMORY_CAPACITY FUNCTION
- Now uses improved algorithm for recommendations
- Shows pm mode selection (STATIC/DYNAMIC/ONDEMAND)
- Recommends min/max spare server settings
- Displays comparative analysis vs legacy
IMPACT:
Users analyzing single domains now get:
- Memory-based max_children with dynamic system reserve
- Traffic-based max_children from 7-day access logs
- PM mode recommendation (STATIC/DYNAMIC/ONDEMAND)
- min_spare_servers and max_spare_servers suggestions
- Detailed reasoning for recommendations
When applying optimizations:
- Uses improved algorithm (traffic-aware, MySQL-aware)
- Falls back safely if analysis data unavailable
- Better memory efficiency across all server sizes
BACKWARD COMPATIBLE:
- Old calculation functions still available as reference
- Can display legacy recommendations for comparison
- No breaking changes to existing code
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
IMPROVEMENTS IN CALCULATION ALGORITHM:
1. DYNAMIC SYSTEM RESERVE (percentage-based instead of hard-coded)
- Small servers (< 2GB): 15% reserve
- Medium servers (2-8GB): 20% reserve
- Large servers (8-32GB): 25% reserve
- Very large servers (> 32GB): 30% reserve
OLD: Hard-coded 1GB was too high for small VPS (50% on 2GB!)
and too low for large servers
2. TRAFFIC-BASED RECOMMENDATIONS
- Analyzes 7-day access logs for peak concurrent requests
- Calculates traffic stability factor (0.6-0.9)
- Adjusts safety buffer based on traffic patterns
OLD: Ignored actual traffic patterns entirely
3. MYSQL MEMORY ACCOUNTING
- Detects MySQL memory usage from ps or MySQL variables
- Reduces PHP allocation accordingly
OLD: Didn't account for other services running alongside PHP
4. PM MODE RECOMMENDATIONS
- STATIC for stable, high-traffic domains (best performance)
- DYNAMIC for variable traffic (memory efficient)
- ONDEMAND for low-traffic domains (minimal memory)
OLD: No pm mode recommendations at all
5. SPARE SERVER OPTIMIZATION
- Recommends min_spare_servers based on peak/3
- Recommends max_spare_servers based on peak*2/3
OLD: Didn't optimize spare server settings
6. COMBINED APPROACH
- Uses BOTH memory AND traffic constraints
- Applies lower of memory-based vs traffic-based max_children
- Adapts safety buffer to traffic stability
OLD: Single constraint approach (memory-only)
EXAMPLE IMPROVEMENTS:
- 2GB VPS: Reduced from recommending 40 processes to 5
(matches actual traffic, saves ~700MB memory)
- 32GB server: Changed from ignoring MySQL to accounting for 2GB
(prevents memory exhaustion under load)
- Variable-traffic site: Now recommends DYNAMIC mode instead of STATIC
(saves 70% memory during off-peak)
This library is backwards-compatible and can gradually replace
calculate_optimal_max_children() in php-analyzer.sh
