SdkLoggerProviderBuilder

SdkLoggerProviderBuilder()

Method Detail

setResource

public SdkLoggerProviderBuilder setResource(Resource resource)

Assign a Resource to be attached to all LogRecordData created by Loggers obtained from the SdkLoggerProvider.

Parameters:

resource - the resource

Returns:

this

addResource

public SdkLoggerProviderBuilder addResource(Resource resource)

Merge a Resource with the current.

Parameters:

resource - Resource to merge with current.

Since:

1.29.0

setLogLimits

public SdkLoggerProviderBuilder setLogLimits(java.util.function.Supplier<LogLimits> logLimitsSupplier)

Assign a Supplier of LogLimits. LogLimits will be retrieved each time a Logger.logRecordBuilder() is called.

The logLimitsSupplier must be thread-safe and return immediately (no remote calls, as contention free as possible).

Parameters:

logLimitsSupplier - the supplier that will be used to retrieve the LogLimits for every LogRecordBuilder.

Returns:

this

addLogRecordProcessor

public SdkLoggerProviderBuilder addLogRecordProcessor(LogRecordProcessor processor)

Add a log processor. LogRecordProcessor.onEmit(Context, ReadWriteLogRecord) will be called each time a log is emitted by Logger instances obtained from the SdkLoggerProvider.

Parameters:

processor - the log processor

Returns:

this

setClock

public SdkLoggerProviderBuilder setClock(Clock clock)

Assign a Clock.

Parameters:

clock - The clock to use for all temporal needs.

Returns:

this

setLoggerConfigurator

SdkLoggerProviderBuilder setLoggerConfigurator(ScopeConfigurator<LoggerConfig> loggerConfigurator)

Set the logger configurator, which computes LoggerConfig for each InstrumentationScopeInfo.

This method is experimental so not public. You may reflectively call it using SdkLoggerProviderUtil.setLoggerConfigurator(SdkLoggerProviderBuilder, ScopeConfigurator).

Overrides any matchers added via addLoggerConfiguratorCondition(Predicate, LoggerConfig).

See Also:

LoggerConfig.configuratorBuilder()

addLoggerConfiguratorCondition

SdkLoggerProviderBuilder addLoggerConfiguratorCondition(java.util.function.Predicate<InstrumentationScopeInfo> scopeMatcher,
                                                        LoggerConfig loggerConfig)

Adds a condition to the logger configurator, which computes LoggerConfig for each InstrumentationScopeInfo.

This method is experimental so not public. You may reflectively call it using SdkLoggerProviderUtil.addLoggerConfiguratorCondition(SdkLoggerProviderBuilder, Predicate, LoggerConfig).

Applies after any previously added conditions.

If setLoggerConfigurator(ScopeConfigurator) was previously called, this condition will only be applied if the Function.apply(Object) returns null for the matched InstrumentationScopeInfo(s).

ScopeConfiguratorBuilder.nameEquals(String), ScopeConfiguratorBuilder.nameMatchesGlob(String)

build

public SdkLoggerProvider build()

Create a SdkLoggerProvider instance.

Returns:

an instance configured with the provided options
