) -> NemoRelayStatus

Creates one typed OpenTelemetry exporter subscriber that writes OTLP to a file.

otel_type must be full, gen_ai, or openinference. output_directory is required. filename may be null to use a default name for the format. format is json_lines (the OpenTelemetry file-exporter specification’s serialization, and the default when null) or proto. mode is overwrite (the default when null) or append.

The projection controls match the endpoint entrypoints: mark_projection is inherit, event, or tool; mark_exclude_names_json, promote_metadata_prefixes_json, and promote_resource_metadata_prefixes_json are JSON arrays of strings; attribute_mappings_json is a JSON array of {"key","alias"} objects; and completed_span_context_ttl_millis must be greater than zero. A null JSON pointer takes the core default.

Safety

Any non-null C strings must be valid and out must be non-null.
