- Fixed 'local' keyword errors outside function scope - Added tracking for pm.mode, pm.max_requests, pm.min_spare_servers, pm.max_spare_servers, pm.process_idle_timeout - Display all pool settings per domain in batch analysis - Added combined memory capacity check (if ALL pools hit max_children) - Status indicators for memory safety: CRITICAL/WARNING/CAUTION/HEALTHY - Complete server-wide big picture analysis in one command
