Laravel Queue Worker for Microservice Dependency Monitoring

Design a robust Laravel queue worker that automatically monitors and self-heals microservice dependencies in a distributed system. Create a background process that can detect service unavailability, log detailed error metrics, and implement intelligent retry mechanisms with exponential backoff. Include circuit breaker logic to prevent cascading failures and generate comprehensive health reports. The solution should integrate with Prometheus metrics and support real-time alerting via Slack/PagerDuty webhooks.
