Summary: Set up the ELK stack (Elasticsearch, Logstash/Filebeat, Kibana) and enable structured logging to centralize observability for AMRIT Spring Boot API services.

Description:
This task involves provisioning ELK components, enabling structured logging in the Spring Boot services, and ensuring end-to-end log ingestion, storage, and visualization for observability.

Acceptance Criteria:

• JSON-structured logging enabled in Spring Boot

•  Filebeat or Logstash installed and forwarding logs to Elasticsearch.
• Elasticsearch cluster provisioned and accepting logs.

• Kibana accessible with appropriate access controls.
• Logs indexed per environment
• Basic Kibana dashboards available for error trends and API activity.
• Ensure incoming API calls, SQL activity, traces are visible in the observability dashboards.
