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 commit removes the now defunkt `ErrorAttributes.ERROR_ATTRIBUTE`
that was introduce to register handled errors as metrics. This has been
replaced since 3.0 by a direct support in Spring Framework and had no
effect whatsoever since that release.
This also updates the documentation to point to the Framework mechanism
that replaced it.
Fixes gh-33731
If @AutoConfigureObservability is applied to a sliced test, it
auto-configures:
- An in-memory MeterRegistry
- A no-op Tracer
- An ObservationRegistry
Closes gh-38568
1. remove unused imports
2. remove redundant semicolon
3. remove empty class body
4. remove redundant 'constructor' keyword
5. remove redundant 'Unit' return type
6. use non-null type if possible
See gh-38708
Prior to this commit, we set in gh-37388 the ObservationRegistry on the
auto-configured JmsTemplate bean. This enables observations and context
propagation when sending JMS messages.
This commit applies the same to the `DefaultJmsListenerContainerFactory`
and the `DefaultJmsListenerContainerFactoryConfigurer`, in order to
enable observations on `@JmsListener` annotated methods.
This commit also refactors the support implemented in gh-37388 to avoid
relying on a bean post processor and instead set the observation
registry directly in the main auto-configuration: while Micrometer core
is an actuator-only dependency, Micrometer Observation API is a compile
dependnecy for spring-jms itself and there is no need to separate
concerns there.
Fixes gh-38613
