Information Keeping Web Application using Spring Boot, Data JPA, Thymeleaf and Spring Security.

'Uses Docker Image available at docker hub link below and postgres official docker image to run the application with docker-compose'

To test use command docker pull badripaudel77/info-keeper-spring-boot-docker:my-info-app

Actuator

• To access actuator endpoint, hit /actuator and you'll see all the available endpoints. By default, only /actuator/health is enabled.
• To get all other endpoints, include "management.endpoints.web.exposure.include=*" in application.properties file.
• For example, now you can access: /actuator/metrics, it will give all the metrics information which you can use to see additional information. Like copy name displayed in /metrics and append that as : metrics/hikaricp.connections
• This will give hikari connection pool info like total no of connections. And other ppts will give other important information.
