If you want to retain the default mappings they must be configured explicitly alongside any custom mappings. 589). Once added, you can open the /actuator/info endpoint and you should ideally see an empty JSON response. We will need Java 8 or higher, Maven, and your favorite IDE as a prerequisite. Allows retrieval and deletion of user sessions from a Spring Session-backed session store. If we want to add static information that would not be changed often, like the name or the description of the project, its a good idea to add some static properties. Most appropriate model fo 0-10 scale integer data. Displays a collated list of all @ConfigurationProperties. ServletContext context = req.getServletContext().getContext(contextPath); } I have verified that info.app.version can retrieve the proper value from pom.xml using @Value. You can enable that on the auto-configured EntityManagerFactory as shown in the following example: Auto-configuration enables the instrumentation of all Spring Data Repository method invocations. In any case, I just tried to add this to a vanilla Spring Boot app (using 1.3.1 and all endpoints were disabled (as expected). If you expect the Cloud Foundry endpoints to always be available at /cloudfoundryapplication/*, regardless of the servers context-path, you will need to explicitly configure that in your application. using the above script the actuator will run on port 9000 and you can send a request to the following URL to access the actuator. @GetMapping("/api/people") Endpoints can be exposed over HTTP using Jersey, Spring MVC, or Spring WebFlux. Adding Build Information using Spring Boot Maven Plugin 5. To enable Prometheus Pushgateway support, add the following dependency to your project: When the Prometheus Pushgateway dependency is present on the classpath and the management.metrics.export.prometheus.pushgateway.enabled property is set to true, a PrometheusPushGatewayManager bean is auto-configured.

The following system metrics are provided: Uptime metrics (both the amount of time the application has been running as well as a fixed gauge of the absolute start time). Our final class should look like this: And if we check the endpoint we can see the newly added properties: We can add build information and additional properties to our /info endpoint using Spring Boot Maven Plugin. To replace the default metric tags, define a MongoConnectionPoolTagsProvider bean, as shown in the following example: To disable the auto-configured connection pool metrics, set the following property: Auto-configuration will bind metrics for Jettys ThreadPool using Micrometers JettyServerThreadPoolMetrics. This happens if a META-INF/build-info.properties file is available in the classpath. We can customize the spring actuator info endpoint using the following properties. As you see in this screenshot, the info endpoint now includes VCS info. Auto-configuration will enable the instrumentation of all available RabbitMQ connection factories with a metric named rabbitmq. What is the state of the art of splitting a binary file by size? If you want to capture all remaining path elements, you can add @Selector(Match=ALL_REMAINING) to the last parameter and make it a type that is conversion compatible with a String[]. An endpoint is considered to be available when it is both enabled and exposed. This section also shows information on the flow control between Axon Server nodes. Subsequently, the BuildInfoContributor will load info from the file. For all other operations the produces clause is application/vnd.spring-boot.actuator.v2+json, application/json. By default, Spring MVC related metrics are tagged with the following information: Simple class name of any exception that was thrown while handling the request. 47 I am able to access endpoints like http://localhost:8081/health, /status, /env, /metrics, /shutdown but not /actuator or /loginfo endpoints. In your case, info was exposed earlier not because you had the property you've provided but because it was exposed by default (along with health). return new JmxMeterRegistry(config, clock, this::toHierarchicalName); Exposes JMX beans over HTTP (when Jolokia is on the classpath, not available for WebFlux). Starting the Prompt Design Site: A New Home in our Stack Exchange Neighborhood, Temporary policy: Generative AI (e.g., ChatGPT) is banned. I want to use maven as build tool }. Spring Actuator /info returns an empty body. Find centralized, trusted content and collaborate around the technologies you use most.

Actuator configures the "liveness" and "readiness" probes as Health Groups; this means that all the Health Groups features are available for them. Since Spring Boots security configuration backs off completely in the presence of any, Because endpoints are technology agnostic, only simple types can be specified in the method signature. Auditing, health, and metrics gathering can also be automatically applied to your application. Some external systems might not be shared by application instances, in which case they could quite naturally be included in a readiness probe. Range requests are not supported when using Jersey. I was able to secure /info endpoint with additional web security configuration (which works beside actuator's default security conf). management.metrics.distribution.percentiles, Publish percentile values computed in your application. Methods are mapped using the standard annotations for Spring MVC and Spring WebFlux such as @RequestMapping and @GetMapping, with the endpoints ID being used as a prefix for the path. Its also possible to override the show-details and roles properties if required: The DataSource health indicator shows the health of both standard data source and routing data source beans. }, @RestController } The correct property for exposing actuator urls over http is management.endpoints.web.exposure.exclude (web instead of jmx).
