From e53ea6f8661a2cac48aad765783825da8a97e73b Mon Sep 17 00:00:00 2001 From: cschantz Date: Thu, 26 Feb 2026 17:31:06 -0500 Subject: [PATCH] Add Website Slowness Diagnostics - Multi-framework analysis tool Features: - Support for 8 frameworks: WordPress, Drupal, Joomla, Magento, Laravel, Node.js, Static HTML, Custom PHP - Auto-detect framework and perform framework-specific analysis - 40+ slowness indicators across database, configuration, resources, performance - Comprehensive diagnostics: database optimization, table fragmentation, indexes, PHP config - Resource analysis: swap usage, I/O performance, process saturation, file descriptors - Domain-specific analysis with no server-wide impact - Handles custom WordPress table prefixes automatically - Graceful error handling for users without shell access - Domain input sanitization (accepts https://www.example.com, etc.) - Temp file management with automatic cleanup - Production-ready with full testing Fixes applied: - Fixed temp session initialization using exported variables - Fixed database credential extraction with proper grep/awk - Added automatic WordPress table prefix detection - Added proper error handling for shell-less cPanel users - Removed problematic progress display calls - Added domain input sanitization for better UX Added to menu: - Main Website Diagnostics menu (Option 3) - Not limited to WordPress, supports all frameworks Co-Authored-By: Claude Haiku 4.5 --- launcher.sh | 14 +- .../website/website-slowness-diagnostics.sh | 2223 +++++++++++++++++ 2 files changed, 2233 insertions(+), 4 deletions(-) create mode 100755 modules/website/website-slowness-diagnostics.sh diff --git a/launcher.sh b/launcher.sh index bd13ba5..be42858 100755 --- a/launcher.sh +++ b/launcher.sh @@ -292,13 +292,18 @@ show_website_menu() { echo -e " ${BLUE}1)${NC} 🔍 Website Error Analyzer - Find 500/config errors (filters bots)" echo -e " ${RED}2)${NC} 🔥 Fast 500 Error Tracker - ONLY 500s + root cause diagnosis" echo "" + echo -e "${BOLD}Performance & Slowness:${NC}" + echo "" + echo -e " ${MAGENTA}3)${NC} 🐢 Website Slowness Diagnostics - Multi-framework analysis" + echo " └─ WordPress, Drupal, Joomla, Magento, Laravel, Node.js, etc." + echo "" echo -e "${BOLD}WordPress Management:${NC}" echo "" - echo -e " ${BLUE}3)${NC} 📦 WordPress Tools → WP-Cron manager & diagnostics" + echo -e " ${BLUE}4)${NC} 📦 WordPress Tools → WP-Cron manager & more tools" echo "" echo -e "${BOLD}Domain Analysis:${NC}" echo "" - echo -e " ${BLUE}4)${NC} 🔶 Cloudflare Detector - Which domains use Cloudflare + location" + echo -e " ${BLUE}5)${NC} 🔶 Cloudflare Detector - Which domains use Cloudflare + location" echo "" echo -e " ${RED}0)${NC} Back to Main Menu" echo "" @@ -314,8 +319,9 @@ handle_website_menu() { case $choice in 1) run_module "website" "website-error-analyzer.sh" ;;
