Required Associated Types§
Required Methods§
sourcefn library_logger(&self, library: Arc<InstrumentationLibrary>) -> Self::Logger
fn library_logger(&self, library: Arc<InstrumentationLibrary>) -> Self::Logger
Returns a new versioned logger with the given instrumentation library.
§Examples
use opentelemetry::InstrumentationLibrary;
use crate::opentelemetry::logs::LoggerProvider;
use opentelemetry_sdk::logs::LoggerProvider as SdkLoggerProvider;
let provider = SdkLoggerProvider::builder().build();
// logger used in applications/binaries
let logger = provider.logger("my_app");
// logger used in libraries/crates that optionally includes version and schema url
let library = std::sync::Arc::new(
InstrumentationLibrary::builder(env!("CARGO_PKG_NAME"))
.with_version(env!("CARGO_PKG_VERSION"))
.with_schema_url("https://opentelemetry.io/schema/1.0.0")
.build(),
);
let logger = provider.library_logger(library);
Provided Methods§
sourcefn versioned_logger(
&self,
name: impl Into<Cow<'static, str>>,
version: Option<Cow<'static, str>>,
schema_url: Option<Cow<'static, str>>,
attributes: Option<Vec<KeyValue>>,
) -> Self::Logger
👎Deprecated since 0.23.0: Please use logger_builder() instead
fn versioned_logger( &self, name: impl Into<Cow<'static, str>>, version: Option<Cow<'static, str>>, schema_url: Option<Cow<'static, str>>, attributes: Option<Vec<KeyValue>>, ) -> Self::Logger
Deprecated, use LoggerProvider::logger_builder()
Returns a new versioned logger with a given name.
The name
should be the application name or the name of the library
providing instrumentation. If the name is empty, then an
implementation-defined default name may be used instead.
Create a new versioned Logger
instance.
sourcefn logger_builder(
&self,
name: impl Into<Cow<'static, str>>,
) -> LoggerBuilder<'_, Self>
fn logger_builder( &self, name: impl Into<Cow<'static, str>>, ) -> LoggerBuilder<'_, Self>
Returns a new builder for creating a Logger
instance
The name
should be the application name or the name of the library
providing instrumentation. If the name is empty, then an
implementation-defined default name may be used instead.
§Examples
use opentelemetry::InstrumentationLibrary;
use crate::opentelemetry::logs::LoggerProvider;
use opentelemetry_sdk::logs::LoggerProvider as SdkLoggerProvider;
let provider = SdkLoggerProvider::builder().build();
// logger used in applications/binaries
let logger = provider.logger_builder("my_app").build();
// logger used in libraries/crates that optionally includes version and schema url
let logger = provider.logger_builder("my_library")
.with_version(env!("CARGO_PKG_VERSION"))
.with_schema_url("https://opentelemetry.io/schema/1.0.0")
