agentcore run batch-evaluation \

  --evaluator Builtin.GoalSuccessRate Builtin.Helpfulness Builtin.Faithfulness \
  --wait

기본적으로는 작업을 agentcore run batch-evaluation 시작하고 즉시 반환합니다(차단 없음). 작업이 터미널 상태에 도달할 때까지 --wait 블록에 전달합니다. --wait를 사용하면 CLI는 프로젝트 구성에서 CloudWatch 로그 그룹 및 서비스 이름을 확인하고, 작업을 시작하고, 최종 상태에 도달할 때까지 차단한 다음, 평가자당 평균 점수를 인쇄합니다.

Batch evaluation completed: acme-eval-a1b2c3d4

Sessions: 10 completed, 0 failed, 10 total

--json를 추가하여 스크립팅을 위해 기계 판독 가능한 결과( batchEvaluationId 및 평가자별 포함averageScore)를 내보내고 -n <name>를 추가하여 실행 간에 결과를 비교할 수 있도록 실행에 레이블을 지정합니다. 예제:

agentcore run batch-evaluation \
  --runtime AcmeSupport \
  --evaluator Builtin.GoalSuccessRate Builtin.Helpfulness Builtin.Faithfulness \
  -n acme_baseline \
  --wait

import boto3

batch_eval_id = response["batchEvaluationId"]
print(f"Started: {batch_eval_id}")

# Poll until complete

CLI는 완료된 배치 평가 작업과 그 결과를 볼 수 있는 일류 명령을 제공합니다. 배치 평가 작업 ID별로 특정 작업을 보거나 과거 작업을 나열합니다.

# View a batch evaluation job and its results
agentcore view batch-evaluation acme-eval-a1b2c3d4

# List batch evaluation jobs
agentcore batch-evaluations history

이러한 명령은 플래그가 지정되지 않은 경우 대화형으로 실행됩니다. 와 같이 비대화형, 기계 판독 가능 출력--json에를 추가합니다agentcore view batch-evaluation acme-eval-a1b2c3d4 --json.

# Get the output location from the batch evaluation result
output = result["outputConfig"]["cloudWatchConfig"]
log_group = output["logGroupName"]
log_stream = output["logStreamName"]

# Read the events
logs_client = boto3.client("logs", region_name=REGION)
response = logs_client.get_log_events(
    logGroupName=log_group,
    logStreamName=log_stream,
)

for event in response["events"]:
    event_attrs = json.loads(event["message"]).get("attributes", {})
    print(f"Score: {event_attrs.get('gen_ai.evaluation.score.value')}")
    print(f"Label: {event_attrs.get('gen_ai.evaluation.score.label')}")
    print(f"Explanation: {event_attrs.get('gen_ai.evaluation.explanation', '')[:200]}")
