Monitoring microservices*

*docker compose solution lacks synchronization scripts for containers startup ordering, app could be run as follows

docker-compose up -d rabbit
docker-compose up -d pg
docker-compose up -d redis
python backend/web_service.py
python backend/message_db.py
python backend/crawler_service.py

backend/web_service.py - web service for task management + REST api + monitoring data display
backend/crawler_service.py - rabbitmq based service, yields tasks from db via rabbitmq and from rabbitmq queu
backend/message_logger.py - logs messages from ampq to file
backend/message_db.py - makes SQL request to the db based on rabbitmq messages and returns results
