Logs API
This Logger API is not designed to be used by application developers, but rather by library developers for the purpose
of integrating existing logging libraries with OpenTelemetry.
Logging from 3rd party loggers
3rd party loggers should log to OpenTelemetry in accordance with the logs bridge API specification.
This means that a "log appender" in the 3rd party logging library (sometimes known as a "handler") should:
- accept an
OpenTelemetry\API\Logs\LoggerProviderInterface, or obtain a globally registered one fromOpenTelemetry\API\Instrumentation\Globals - obtain a
Loggerfrom the logger provider (optionally adding any resources that should be associated with logs emitted) - convert logs from its own log format into OpenTelemetry's
LogRecordformat - send the logs to OpenTelemetry via
Logger::logRecord()
See monolog-otel-integration for an example.
