This commit improves the `health` endpoint to run health check for a
particular component or, if that component is itself a composite, an
instance of that component.
Concretely, it is now possible to issue a `GET` on
`/actuator/health/{component}` and
`/actuator/health/{component}/instance` to retrieve the health of a
component or an instance of a composite component, respectively.
If details cannot be showed for the current user, any request leads to a
404 and does not invoke the health check at all.
Closes gh-8865
This commit updates the initial proposal to add support for reactive
use cases as well. A reactive application can use
ReactiveHealthIndicatorRegistry as an alternative to
HealthIndicatorRegistry.
Closes gh-4965
This commit introduces HealthIndicatorRegistry which handles
registration of HealthIndicator instances. Registering new
HealthIndicator instances is now possible in runtime.
See gh-4965
This commit improves the initial proposal by providing a by name read
operation that returns the detail of a particular cache. It also adds
more tests and complete API documentation for the feature.
Closes gh-12216
This commits adds an actuator endpoint which lists the caches per
context and cacheManager and provides a delete operation to clear the
caches. As the statistics are exposed via the metrics endpoint they are
not included

This commit adds support for Actuator Metrics for WebClient.
This support mirrors the current behavior for `RestTemplate`, reusing
the same metric name `"http.client.requests"` and tags.
`WebClient` is instrumented by a `MetricsWebClientFilterFunction` which
is applied by a `WebClientCustomizer`. This instrumentation happens
automatically only if you create an instance of `WebClient` using an
auto-configured `WebClient.Builder` bean.
This infrastructure is reusing de facto the `MeterFilter` that has been
added for `RestTemplate` in order to limit the "uri" tag cardinality.
Closes gh-12228
This commit makes sure to respect the MBeanServer#invoke contract by
wrapping any user-defined exception in an MBeanException. Also, any
exception not from the JDK is translated, as it may lead to unexpected
issue on the client if that class isn't present. This is consistent
with our operation result mapping strategy.
Closes gh-10448
