Subject: [PATCH] Multi-panel support for 500-error-tracker.sh (Class C
 refactoring)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MAJOR REFACTORING:
Fast 500 error tracking tool that scans Apache access logs for 500 errors,
filters out bot traffic, and diagnoses root causes. Now supports all control panels.

KEY CHANGES:

1. Added Required Sources (lines 12-14):
   - source system-detect.sh (for SYS_CONTROL_PANEL, SYS_LOG_DIR)
   - source user-manager.sh (for future get_user_domains if needed)
   - Already had common-functions.sh and ip-reputation.sh

2. Configuration (lines 61-63):
   - Changed DOMLOGS_DIR from hardcoded "/var/log/apache2/domlogs" to "${SYS_LOG_DIR}"
   - Added CONTROL_PANEL="${SYS_CONTROL_PANEL}"

3. Domain→User Lookup (lines 85-99):
   - Replaced cPanel-only /var/cpanel/users lookup
   - Multi-panel case statement:
     * cPanel: /etc/userdatadomains
     * InterWorx: vhost config + SuexecUserGroup
     * Plesk: plesk bin subscription --info
   - Fallback to "unknown" if lookup fails

4. Log Discovery (lines 189-210):
   - Complete multi-panel rewrite using case statement

   cPanel (line 192-195):
   - Uses $DOMLOGS_DIR (from SYS_LOG_DIR)
   - Maintains existing exclusion filters

   InterWorx (line 196-199):
   - Searches /home/*/var/*/logs/access_log
   - Per-domain logs in user home directories

   Plesk (line 200-203):
   - Searches /var/www/vhosts/system/*/logs/
   - Includes both access_log and access_ssl_log

   Standalone (line 204-208):
   - Tries /var/log/httpd/access_log
   - Tries /var/log/apache2/access.log

IMPACT:
- Critical diagnostic tool now works on cPanel, InterWorx, Plesk, standalone
- Properly detects logs based on control panel structure
- Domain→user mapping works across all panels
- No hardcoded paths remain

COMPLIANCE: Class C ✅
- ✅ Uses system-detect.sh variables (SYS_CONTROL_PANEL, SYS_LOG_DIR)
- ✅ Multi-panel case statements for user lookup and log discovery
- ✅ No hardcoded panel-specific paths
- ✅ Syntax verified with bash -n
