# Database Deadlock Detector
## Overview
Detect, analyze, and prevent database deadlocks in PostgreSQL, MySQL, and MongoDB by examining lock wait graphs, parsing deadlock log entries, identifying the application code paths that cause lock ordering conflicts, and implementing preventive patterns.
## Prerequisites
- Database credentials with access to lock monitoring views (`pg_locks`, `INNODB_LOCK_WAITS`)
- `psql` or `mysql` CLI for executing diagnostic queries
- PostgreSQL: `log_lock_waits = on` and `deadlock_timeout = 1s` configured
- MySQL: `innodb_print_all_deadlocks = ON` for deadlock logging to error log
- Access to database error logs for deadlock event parsing
- Application source code access for identifying lock-inducing code paths
