-==== EurekaClient with Jersey
+==== Underlying HTTP clients
+
+`EurekaClient` uses either `RestTemplate`, `WebClient` or `JerseyClient` under the hood. In order to use the `EurekaClient`, you need to have one of the supported HTTP clients on your classpath.
+
+To use `RestTemplate`, add `spring-boot-starter-web` to your dependencies. To use `WebClient`, add `spring-boot-starter-webflux` to your dependencies. If both `RestTemplate` and `WebClient` are on the classpath when `eureka.client.webclient.enabled` is set to `true`, `WebClient` is used. Otherwise, `RestTemplate` is used.

-By default, EurekaClient uses Spring's `RestTemplate` for HTTP communication.
 If you wish to use Jersey instead, you need to add the Jersey dependencies to your classpath.
 The following example shows the dependencies you need to add:

+=== Metrics
+
+`EurekaInstanceMonitor` listens to events related to Eureka instance registration and creates/updates `Gauge`s for Eureka instance information in Micrometer's `MeterRegistry`. By default, this behavior is disabled. If you want to enable it, you need to set `eureka.server.metrics.enabled` to `true`.
+
+By default, the `Gauge`s are named `eureka.server.instances` and have the following tags:
+
+- `application`: application name
+- `status`: instance status (`UP`, `DOWN`, `STARTING`, `OUT_OF_SERVICE`, `UNKNOWN`, see: `com.netflix.appinfo.InstanceInfo.InstanceStatus`)

+You can add additional tags by injecting your own implementation of `EurekaInstanceTagsProvider`.
