* feat(otel): emit the gen_ai.client.operation.exception event on failed LLM calls The GenAI semantic conventions record failures of a GenAI client operation as a log-based event named gen_ai.client.operation.exception, carrying the exception.type / exception.message / exception.stacktrace trio at severity WARN and correlated to the failed span. OTel v2 never emitted it: a failed LLM call produced only the deprecated error.* span attributes, a generic exception span event without a stacktrace, and the stacktrace under the vendor key litellm.provider.error.stack_trace. Build the logs pipeline (LoggerProvider + console/OTLP log exporters mirroring the metrics plumbing) and record the event behind the enable_events flag, which until now was defined but consumed nowhere. An operator-configured LoggerProvider global is reused so the events ride their existing logs pipeline; an explicit NoOpLoggerProvider global is honored as an opt-out and builds no recorder at all. The existing span-side error surface (error.type, error.message, the exception span event, and the litellm.provider.error.* detail keys) is untouched for backwards compatibility. * fix(otel): always ride the semconv-required exception pair on the GenAI event Filtering the event attributes on truthiness conflated "absent" with "empty", so an empty exception.type or exception.message would have been dropped, leaving an event with neither semconv-required field. Build the attributes so the pair is unconditional and only the recommended stacktrace is omitted when the payload carries none. * docs(otel): document the events plumbing module in the package README * test(otel): cover the log exporter selection and logs endpoint normalization The new logs plumbing had no coverage for exporter-kind selection, the console fallback for an unrecognized kind, the /v1/logs signal-path rewriting that lets one OTEL_ENDPOINT serve every signal, or the simple-vs-batch processor split. |
