Performance: Actuator endpoints overview
MEDIUM IMPACT
Actuator endpoints impact the server response time and network load, affecting how quickly monitoring data is available without slowing down the main application.

Actuator endpoints overview in Spring Boot - Performance & Optimization
Exposing all actuator endpoints in production
Spring Boot
management.endpoints.web.exposure.include=health,info
Limits exposure to only essential endpoints, reducing server processing and network traffic.
📈 Performance Gainreduces server load and network usage, improving response speed
Exposing all actuator endpoints in production
Spring Boot
management.endpoints.web.exposure.include=*
Exposes all endpoints, increasing server processing and network traffic, which can slow down response times and increase security risks.
📉 Performance Costadds unnecessary server load and network overhead, potentially blocking main app threads
Performance Comparison
| Pattern | Server Load | Network Traffic | Response Time | Verdict |
|---|---|---|---|---|
| Expose all endpoints | High | High | Slower | [X] Bad |
| Expose minimal endpoints | Low | Low | Faster | [OK] Good |
Rendering Pipeline
Actuator endpoints are processed by the server and do not affect browser rendering directly but impact backend response times and network latency.

⚠️ BottleneckServer Processing when many endpoints or heavy metrics are enabled
Optimization Tips
1Only expose actuator endpoints needed for monitoring.
2Avoid exposing heavy or sensitive endpoints in production.
3Use caching or asynchronous collection for expensive metrics.

What is the main performance risk of exposing all actuator endpoints in production?
DevTools: Network
How to check: Open DevTools, go to Network tab, trigger actuator endpoint requests, and observe response times and payload sizes.
What to look for: Look for large payloads or slow responses indicating heavy or unnecessary actuator data.
