Here are the top 20 Spring Boot Actuator endpoints, explaining what they do, their usefulness, and how they might be improved in the future:

1. /health
What it does: Provides a real-time status of the application’s health.
Usefulness: Vital for monitoring the general health of the system, particularly in production environments.
When to use: Used in production to check if dependencies (like databases) and the application itself are operational.
Improvement: Could offer more granular, detailed health checks for specific components.
2. /metrics
What it does: Exposes a wide array of metrics about the application’s performance, including JVM stats, memory usage, and request statistics.
Usefulness: Helps track performance and identify bottlenecks.
When to use: Useful for developers and DevOps teams when monitoring system performance or debugging issues.
Improvement: A more intuitive grouping or filtering of metrics could make it easier to focus on critical stats.
3. /info
What it does: Displays general information about the application, such as version or description.
Usefulness: Helpful for quick access to basic information about the deployed application.
When to use: Primarily used by developers or during the deployment process to check version details.
4. /env
What it does: Exposes the environment properties of the application.
Usefulness: Provides insights into application configurations, which is helpful for troubleshooting.
When to use: Useful in debugging configuration issues or verifying correct environment setups.

6. /threaddump
What it does: Provides a snapshot of the current thread activity in the JVM.
Usefulness: Essential for diagnosing performance issues, especially when an application is stuck.
When to use: Used during troubleshooting when performance problems arise due to thread locking or deadlocks.
Improvement: Could offer more visualization or analysis of threads, making interpretation easier.
9. /heapdump
What it does: Generates a heap dump of the JVM, useful for memory analysis.
Usefulness: Critical for diagnosing memory leaks or excessive memory consumption.
When to use: Used during troubleshooting when memory-related issues are suspected.
Improvement: Could offer lightweight, real-time memory insights without generating full dumps.
10. /auditevents
What it does: Lists audit events, such as user logins or other security-related actions.
Usefulness: Tracks important security events and user actions.
When to use: Useful in auditing and monitoring who accessed the system and what changes were made.
Improvement: Could provide more detailed filtering and analysis of event types.
11. /conditions
What it does: Displays the conditions under which beans were included or excluded in the application context.
Usefulness: Essential for debugging bean configuration or conditional loading issues.
When to use: Helpful when diagnosing issues with beans being incorrectly included or excluded.
Improvement: Could offer detailed explanations or suggestions for why conditions failed or passed.
12. /shutdown
What it does: Allows for a graceful shutdown of the application.
Usefulness: Useful for automating shutdown procedures or stopping the application safely in production.
When to use: Used in scenarios requiring an automated shutdown without manual intervention.

15. /caches
What it does: Lists all the cache entries and their stats.
Usefulness: Helps in monitoring cache efficiency and hit/miss ratios.
When to use: Used in performance tuning or ensuring cache effectiveness.
Improvement: Could offer cache eviction suggestions or detailed analysis.
16. /sessions
What it does: Provides a view of the active user sessions and their details.
Usefulness: Helps in monitoring active users and session details in real time.

18. /prometheus
What it does: Exposes metrics in a format suitable for Prometheus.
Usefulness: Integrates easily with monitoring systems like Prometheus for real-time data visualization.
19. /jolokia
What it does: Provides JMX over HTTP, making it easier to manage MBeans remotely.

20. /custom (User-defined)
What it does: Allows you to create custom endpoints for application-specific needs.
Usefulness: Lets you expose any custom business logic or metrics not covered by the built-in endpoints.
