Update all configuration examples in the docs to YAML and make use of
the new `configblocks` spring-asciidoctor-extensions feature to
automatically create both "Properties" and "Yaml" versions.
Closes gh-23515
With the introduction of health indicators that only require the
CqlSession, this commit deprecates the health indicators that require
Spring Data since the latter build on top of the former.
Closes gh-23226
This commit builds on top of gh-22603 and exposes data collected by the
`BufferingApplicationStartup` on a dedicated `"/startup"` Actuator
endpoint.
Closes gh-23213
Prior to this commit, the application availability infrastructure
would mix the `AvailabilityState`, the `HealthIndicator` and the
`HealthGroup` concepts and would not align with the rest.
This commit auto-configures the livenessState and readinessState
health indicators with the relevant configuration properties.
Unlike other indicators, they are not enabled by default but might
be in future versions.
This also moves the `management.health.probes.enabled` property
to `management.endpoint.health.probes.enabled` since "probes" here
is not a health indicator but rather a configuration flag for the
health endpoint.
Finally, the probes auto-configuration is refined to automatically
add liveness and readiness indicators for the probes group if
they're not already present.
Closes gh-22107
This commit mentions the `management.health.probes.enabled`
configuration property in the Kubernetes Probes section of the Actuator
chapter.
Enabling this property is required if we need to expose Kubernetes
Probes in a non-Kubernetes environment.
Fixes gh-21505
This commit removes the support for Reactor Netty metrics since it
seems that Spring Boot should not use this feature:
* HTTP metrics are already covered by WebFlux
* TCP metrics are only meant to TCP server/clients
* allocator metrics are already provided by Netty and there is
no specific API to enable them here.
Closes gh-19388
This commit enables the production of TCP and buffer allocator metrics
for Reactor Netty, client and server.
When applications use auto-configured server
(`NettyReactiveWebServerFactory`) and client (through
`WebClient.Builder`) instances, metrics will be enabled.
Note that HTTP metrics are not enabled here, since similar metrics are
already produced at the WebFlux level. Also, to avoid cardinality
explosion of metrics (through the URI tag), Reactor Netty offers
configurable infrastructure to deduplicate URI tags by turning expanded
URI instances into templated URIs. This is not targeted for Spring
usage.
Closes gh-19388
