问题 I have a running Springboot application which serves the URL http://localhost:8081/topics and returns me JSON response as expected. I added actuator dependency <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> <scope>test</scope> </dependency> as suggested in tutorial But when I hit http://localhost:8081/health it does not give expected result. It says { "timestamp": 1497952368055, "status": 404, "error": "Not Found", "message": "No

问题 I updated an already existing application from Spring Boot 1.3 to 2.0.1. This application makes use of the Actuator and exposes a REST-style API. In Boot 1.3 the API could be used without authentication and the actuator endpoint was configured to be password protected: security.user.name=foo security.user.password=bar security-user.role=ADMIN I updated this like documented in the configuration changelog and renamed the entries from security.user.name to spring.security.user.name and alike.

问题 I moved to Spring Boot 2.0.0 RC1 from 1.5.10 and I am stuck with actuator in the latest version. How can I enable expose and enable all actuator endpoints? The only endpoints that get exposed are: { "_links": { "self": { "href": "http://127.0.0.1:8080/actuator", "templated": false }, "health": { "href": "http://127.0.0.1:8080/actuator/health", "templated": false }, "info": { "href": "http://127.0.0.1:8080/actuator/info", "templated": false } } } This is my application.properties files.

问题 In my SpringBoot application, I have a FixedRateScheduledTask. I want to dynamically change the fixed interval upon a refresh event. Note that depending on the processing time, there could be several parallel threads, thanks to Async. Upon a refresh event, I cancel ed the current ScheduledTask and re-added a new FixedRateTask with new value for interval . Below is my code @Configuration @EnableAsync @EnableScheduling public class Scheduler implements SchedulingConfigurer, ApplicationListener

问题 According to the documentation of the spring boot actuator Auto-configuration enables the instrumentation of requests handled by Spring MVC. When management.metrics.web.server.auto-time-requests is true, this instrumentation occurs for all requests. Alternatively, when set to false, you can enable instrumentation by adding @Timed And By default, metrics are generated with the name, http.server.requests When I access the /metrics endpoint I am getting { "mem": 405105, "mem.free": 150352,

问题 I was looking a while and didn't seem to find the answer. I'm using Spring boot 2, Spring Kafka 2.1.4 and I want to see the kafka consumer metrics in the /metrics endpoint of spring boot actuator. What I don't understand is - should I implenemt the exposure myself or is this comes out-of-box in boot 2 ? If I to implement this my self, what is the best way to do it? 回答1: Targeted for micrometer v1.1.0 is the KafkaConsumerMetrics implementation of MeterBinder . This should expose the kafka
