NOTE: reminder that
the Logs Bridge API
is not meant for end users. Log appenders use the API to bridge logs from existing log
frameworks (e.g. JUL, Log4j, SLf4J, Logback) into OpenTelemetry. Users configure the Log SDK to
dictate how logs are processed and exported.
See opentelemetry.io for
documentation on usage.
