This commit adds an abstraction that provides a standard manner to
retrieve various metadata that are shared by most data sources.
DataSourceMetadata is implemented by the three data source
implementations that boot supports out-of-the-box: Tomcat, Hikari and
Commons dbcp.
This abstraction is used to provide two additional metrics per data
source defined in the application: the number of allocated
connection(s) (.active) and the current usage of the connection pool
(.usage).
All such metrics share the 'datasource.' prefix. The prefix is further
qualified for each data source:
* If the data source is the primary data source (that is either the
only available data source or the one flagged @Primary amongst the
existing ones), the prefix is "datasource.primary"
* If the data source bean name ends with "dataSource", the prefix is
the name of the bean without it (i.e. batchDataSource becomes batch)
* In all other cases, the name of the bean is used
It is possible to override part or all of those defaults by
registering a bean with a customized version of
DataSourcePublicMetrics.
Additional DataSourceMetadata implementations for other data source
types can be added very easily, check
DataourceMetadataProvidersConfiguration for more details.
Fixes gh-1013
This commit binds RepositoryRestConfiguration to the spring.data.rest
prefix so that any of its property can be customized through the
environment.
If a RepositoryRestMvcConfiguration is defined in the context, those
customization do not apply, as it was the case before.
Fixes gh-1171
Add `spring.datasource.jndi-name` property to allow a DataSource to be
looked up from JNDI as an alternative to defining a URL connection.
Fixes gh-989
Rework flexible PublicMetrics registration introduced in 2be6b3e4 to
restore compatibility with v1.1 VanillaPublicMetrics. The new
MetricReaderPublicMetrics class now exposes metrics from a MetricReader
and VanillaPublicMetrics is deprecated. The MetricsEndpoint can now
exposes a collection of PublicMetric interface directly.
See gh-1094
This commit fixes some inconsistent or outdated keys in the
documentation. More specifically:
* allowSessionOverride is no longer a template parameter
* templateEncoding has been renamed to charSet
* Groovy templates do not have the same configuration hierarchy, hence
they don't share all settings
* spring.data.elasticsearch.local does not seem to exist
* flyway prefix and suffix should be sqlMigrationPrefix and suffix
* spring.rabbitmq.virtualHost had a typo
* endpoints.error.path is not a valid property
* shell.command-path-patterns had a typo
* spring.datasource.max-wait had a typo
Fixes gh-1226
This commit permits the use of several PublicMetrics instances by
default. Previously, only one PublicMetrics service could be specified
and a user configuration would remove all the defaulting.
VanillaPublicMetrics now takes a collection of PublicMetrics and
invokes them in sequence to build the final collection of metrics.
The system-related metrics have been moved to SystemPublicMetrics and
are registered by default.
Also updated the documentation to mention this feature and how it
could be fully overridden.
