Bases: OnlineEvaluationBaseProps

Properties for creating an OnlineEvaluationConfig.

Parameters:

  • online_evaluation_config_name (str) – The name of the online evaluation configuration. Must be unique within your account. Valid characters are a-z, A-Z, 0-9, _ (underscore). Must start with a letter and can be up to 48 characters long.

  • description (Optional[str]) – The description of the online evaluation configuration. Default: - No description

  • execution_role (Optional[IRole]) – The IAM role that provides permissions for the evaluation to access AWS services. If not provided, a role will be created automatically with the required permissions including cross-region Bedrock model invocation (to support cross-region inference profiles). For strict cost controls or data residency compliance, provide a custom role with region-scoped permissions. Default: - A new role will be created

  • execution_status (Optional[ExecutionStatus]) – The execution status of the online evaluation configuration. Controls whether the evaluation actively processes agent traces. Default: ExecutionStatus.ENABLED

  • filters (Optional[Sequence[Union[FilterConfig, Dict[str, Any]]]]) – The list of filters that determine which agent traces should be evaluated. Default: - No filters (evaluate all sampled traces)

  • sampling_percentage (Union[int, float, None]) – The percentage of agent traces to sample for evaluation. Default: 10

  • session_timeout (Optional[Duration]) – The duration of inactivity after which an agent session is considered complete and ready for evaluation. Must be between 1 minute and 1440 minutes (24 hours). Default: Duration.minutes(15)

  • data_source (DataSourceConfig) – The data source configuration that specifies where to read agent traces from.

  • evaluators (Sequence[EvaluatorSelector]) – The list of evaluators to apply during online evaluation. Can include both built-in evaluators and custom evaluators.

  • tags (Optional[Mapping[str, str]]) – Tags for the online evaluation configuration. A list of key:value pairs of tags to apply to this OnlineEvaluationConfig resource. Default: - No tags
