This commit adds micrometer's default values for each monitoring
system with tests that validate those defaults are consistent. This
makes sure that those defaults are part of the metadata and any tooling
support that uses it.
Closes gh-12089
Remove custom `SpringIntegrationMetrics` and instead provide
auto-configuration to the direct Micrometer support added in Spring
Integration 5.0.2.
Closes gh-11985
Previously, links were only provide to web endpoints. This commit
expands link resolution to also provide links for servlet endpoints,
controller endpoints, and rest controller endpoints.
Closes gh-11902
Refactor `*ExportConfiguration` classes to be regular auto-configuration
classes.
Also removed the `@ConditionalOnProperty` guards for `.enabled` properties
since auto-configuration can now be excluded in the usual way. Enabled
properties remain where applicable and are adapted for Micrometer to use
as it sees fit.
Fixes gh-11838
Add a new `WebServerApplicationContext` interface that provides a common
abstraction for all application contexts that create and manage the
lifecycle of an embedded `WebServer`.
Allows server namespaces to become a first-class concept (rather
subverting `ConfigurableWebApplicationContext.getNamespace()`) and
allow us to drop `getServerId()` from `WebServerInitializedEvent`.
Also helps to improve `ManagementContextAutoConfiguration` and
`ManagementContextFactory`.
Fixes gh-11881
Add MeterFilter to restrict the maximum number of web client URI tags
created. Prior to this commit, if a user was manually building URIs for
use with a RestTemplate (rather than using uriVariables) the JVM could
run out of memory.

Update micrometer auto-configuration so that a `CompositeMeterRegistry`
is only created when more than one `MeterRegistry` bean is declared.
When a composite is crated, it is marked as `@Primary` so that it
can be directly injected. Meter registries can now be defined directly
as beans, and auto-configuration can back off in the usual way.
The `MeterRegistryConfigurer` is now called `MeterRegistryCustomizer`
and is generically types so it's easy to apply customizations to a
particular `MeterRegistry` implementation.

Previously, the test in MetricsAutoConfigurationIntegrationTests was
testing the functionality of WebMvcMetricsFilter to verify that the
auto-configuration had registered the filter for async dispatches.
This test was complex and covered the same code as a test in
WebMvcMetricsFilterTests.
This commit reworks the test to examine the dispatcher types on the
filter registration directly instead.
Closes gh-11826
Add `@ControllerEndpoint` and `@RestControllerEndpoint` annotations that
can be used to develop a Spring-only request mapped endpoint. Both
Spring MVC and Spring WebFlux are supported.
This feature is primarily for use when deeper Spring integration is
required or when existing Spring Boot 1.5 projects want to migrate to
Spring Boot 2.0 without re-writing existing endpoints. It comes at the
expense of portability, since such endpoints will be missing from
Jersey.
Fixes gh-10257
Create a `PathMappedEndpoint` interface that allows any `ExposedEndpoint`
to provide root path details. The `EndpointPathResolver` interface has
been renamed to `PathMapper` and is now only used during endpoint
discovery.
`EndpointPathProvider` has been replaced with `PathMappedEndpoints`
which simply finds relevant path mapped endpoints.
Fixes gh-10985
Refactor several areas of the actuator endpoint code in order to make
future extensions easier. The primary goal is to introduce the concept
of an `ExposableEndpoint` that has technology specific subclasses and
can carry additional data for filters to use. Many other changes have
been made along the way including:
* A new EndpointSupplier interface that allows cleaner separation of
supplying vs discovering endpoints. This allows cleaner class names
and allows for better auto-configuration since a user can choose to
provide their own supplier entirely.
* A `DiscoveredEndpoint` interface that allows the `EndpointFilter`
to be greatly simplified. A filter now doesn't need to know about
discovery concerns unless absolutely necessary.
* Improved naming and package structure. Many technology specific
concerns are now grouped in a better way. Related concerns are
co-located and concepts from one area no longer leakage into another.
* Simplified `HandlerMapping` implementations. Many common concerns have
been pulled up helping to create simpler subclasses.
* Simplified JMX adapters. Many of the intermediary `Info` classes have
been removed. The `DiscoveredJmxOperation` is now responsible for
mapping methods to operations.
* A specific @`HealthEndpointCloudFoundryExtension` for Cloud Foundry.
The extension logic used to create a "full" health endpoint extension
has been made explicit.

Improve the structure of the response and include mappings from
WebFlux and Servlet and Filter registrations in addition to the
mappings from Spring MVC.
Closes gh-9979
Previously, a number of Actuator endpoints ignored a context hierarchy
or assumed that it would always be linear. This commit reworks the
affected endpoints so that the no longer assume a linear hierarchy.
A side-effect of a non-linear hierarchy is that there may be multiple
different beans with the same name (in a linear hierarchy, a bean
with the same name as one in an ancestor context, replaces that bean).
The affected endpoints have also been updated so that, when bean names
are used as keys, those keys are grouped by application context. This
prevents a bean in one context from accidentially overwriting a bean
in another context.
Closes gh-11019
This commit applies most `server.tomcat.*` configuration
properties to Tomcat when set up as a reactive web server.
Some Servlet-specific properties are not applied:
* server.tomcat.additional-tld-skip-patterns
* server.tomcat.redirect-context-root
* server.tomcat.use-relative-redirects
Fixes gh-11334
Change `CacheMeterBinderProvider` to include a cache type
generic which helps to simplify implementations. Also move
and extract a few classes.
See gh-11221
This commit adds GC and thread jvm metrics to the existing memory
metrics. All three are now managed by a unique
management.metrics.binders.jvm.enabled property.
Closes gh-11425
This commit moves management.server.context-path to
management.server.servlet.context-path to align with the configuration
key for the application's main context path.
Closes gh-11359
`CorsEndpointProperties` lives in `endpoint.web.servlet` but is also used
in `endpoint.web.reactive`, so this PR moves it to its common parent
package.
This commit also extracts `CorsConfiguration` creation logic duplicated
in `WebMvcEndpointManagementContextConfiguration` and
`WebFluxEndpointManagementContextConfiguration` into
`CorsEndpointProperties`.
See gh-11439
Previously, the Health web extension was defined in the management
context and, as a result, it wasn't found when a separate port was
required. The side effect is that anything that the health web extension
does was not active anymore in that case.
This commit makes sure that the extension is always defined as part of
the main context where operations are discovered and merged.
Closes gh-11285
MeterRegistryConfigurers are now applied within the Bean method
creating the CompositeMeterRegistry, instead of applying them
later in its lifecycle, when the bean itself could have been
injected somewhere.
Fixes gh-11319
Previously, a `ReactiveHealthIndicator` bean was exposed to define the
health indicator to use for the reactive endpoint. Having it exposed as
a bean has the side effect that the regular `HealthIndicator` composite
is picked up and a "reactive" entry is added to the health details.
This commit creates such indicator internally as it should be.
Closes gh-11222
This change replaces fallback logic in PropertiesConfigAdapter and its
descendants such that instead of falling back to default "empty" config
it delegates to superinterface default implementation of the same class.
This allows default implementation to call back to other properties,
like DatadogConfig.uri() does.
See gh-11135
Drop the status endpoint and merge functionality back into the health
endpoint. The `management.endpoint.health.show-details` property can
be used to change if full details, or just the status is displayed.
Fixes gh-11113
Update appropriate configuration properties to use the `Duration`
type, rather than an ad-hoc mix of milliseconds or seconds.
Configuration properties can now be defined in a consistent and readable
way. For example `server.session.timeout=5m`.
Properties that were previously declared using seconds are annotated
with `@DurationUnit` to ensure a smooth upgrade experience. For example
`server.session.timeout=20` continues to mean 20 seconds.
Fixes gh-11080
Update endpoint code to provide cleaner separation of concerns.
Specifically, the top level endpoint package is no longer aware of
the fact that JMX and HTTP are ultimately used to expose endpoints.
Caching concerns have also been abstracted behind a general purpose
`OperationMethodInvokerAdvisor` interface.
Configuration properties have been refined to further enforce
separation. The `management.endpoint.<name>` prefix provides
configuration for a single endpoint (including enable and cache
time-to-live). These properties are now technology agnostic (they
don't include `web` or `jmx` sub properties).
The `management.endpoints.<technology>` prefix provide exposure specific
configuration. For example, `management.endpoints.web.path-mapping`
allow endpoint URLs to be changed.
Endpoint enabled/disabled logic has been simplified so that endpoints
can't be disabled per exposure technology. Instead a filter based
approach is used to allow refinement of what endpoints are exposed over
a given technology.
Fixes gh-10176
This commit removes two properties that were remove in earlier
milestones of Spring Boot 2 and reintroduced with the support of
micrometer.
Closes gh-11015
Changes made in f1cfad67 mean that the web-specific extension is no
longer required as the infrastructure now automatically produces a
bad request (400) response when a required query parameter is absent.
