Prior to this commit, applications could declare Actuator Endpoints
using web framework-specific annotations, such as `@ServletEndpoint`,
@ControllerEndpoint and @RestControllerEndpoint.
Such annotations are closely tied to the programming model of specific
web technologies, such as Servlet or Spring MVC. Unlike other
`@Endpoint` support, they are not portable and will not work
transparently over blocking/reactive and transports.
Because of the strong adherence of this support with the underlying
infrastructure, it makes it impossible to evolve the implementation of
Actuator support without breaking this use case. The reference
documentation has been advocating for using `@Endpoint` and
`@*Operation` for custom endpoints for a long time now.
This commit deprecates this specific support in favor of the recommended
approach.
Closes gh-31768
Prior to this commit, the `ClientObservationConventionAdapter` would
overwrite a request builder attribute. This would happen when the
request is not fully built when the observation starts. At that point,
the tags are built for long task timers, but not for the actual metric.
This effectively overrides the correct value of the URI template in the
builder.
This commit removes this builder update which was invalid in the first
place.
Fixes gh-40330
Deprecates the support for simpleclient but ensures that it can work in
conjunction with support for the latest Prometheus client
auto-configuration.
This involves breaking changes to update public classes to support the
latest Prometheus client. Deprecated support for Prometheus simpleclient
is provided in renamed classes.

Properties under `server.ssl.server-name-bundles` and
`management.server.ssl.server-name-bundles` can be used to configure
mappings of host names to SSL bundles to support SNI in embedded web
servers.
Closes gh-26022
Update `ZipkinHttpClientSenderTests` to use one mock server per test
rather than a shared static. For some reason the mock server sometimes
seems to get itself in a deadlock state which causes the client to
fail with a `HttpTimeoutException`.
This commit simplifies the generics used for SessionRepository and
FindByIdNameSessionRepository as their type signatures already declare
that `S` extends from `Session`.
See gh-39751
Brave can work without zipkin2 on the classpath, OpenTelemetry can't.
To not force users to have zipkin2 on the classpath, move it into the
OpenTelemetry auto-configuration.
See gh-39049
This commit moves the "micrometer.observations.*" configuration
properties to "management.observations.*" namespace, as it was
introduced in the wrong namespace initially.
The former configuration property is deprecated and will be removed in a
future version.
Fixes gh-39600
At present, Actuator sessions endpoint is supported only on a Servlet stack and also requires an indexed session repository. With Spring Session moving to non-indexed session repositories as a default for some session stores, this means that sessions endpoint won't be available unless users opt into a (non-default) indexed session repository.
This commit updates SessionEndpoint so that it is able to work with a non-indexed session repository. In such setup, it exposes operations for fetching session by id and deleting the session.
Additionally, this also adds support for reactive stack by introducing ReactiveSessionEndpoint and its auto-configuration support.
See gh-32046
Prior to this commit, the Micrometer annotations support (`@Timed`,
`@Counted`...) was guarded by the presence of both Micrometer and
AspectJ on the classpath.
This signal is too weak, considering the startup performance impact and
the fact that the AspectJ dependency can be brought transitively in many
cases.
This commit adds a new `micrometer.observations.annotations.enabled`
property that is set to `false` by default to only process the
annotations support when this property is enabled.
Fixes gh-39128
This is a follow-on from afad358 and ensures that the auto-configured
security for Actuator in a WebFlux app has an authentication manager
to back its use of HTTP basic and form login.
Fixes gh-39069
