Create a Centralized System for Monitoring, Alerting, and Logging

Create and put into place a centralized observability system, including monitoring, alerting, and logging for a scalable application. For structured application logging, use Winston; for metrics collecting and monitoring, use Prometheus; and for log aggregation and visualization, use the ELK Stack (Elasticsearch, Logstash, Kibana).

Your solution has to specify:

• Logging strategy (formats, levels, storage, and organized logging)
• Key performance indicators, system metrics, and dashboards are examples of metrics that are gathered and monitored.
• Alerting systems (notification channels, triggers, and thresholds)
• Architecture for integrating the monitoring, alerting, and logging components
• Performance considerations, fault tolerance, and scalability
• Best practices for observability, security, and log retention

When appropriate, include configuration examples and a step-by-step implementation strategy.
