本頁說明如何使用 AML AI 產生的平台記錄，這些記錄屬於 Cloud Logging 的一部分。AML AI 會使用 Logging API 服務名稱 financialservices.googleapis.com 記錄下列活動：
- 建立引擎設定 (調整)
- 建立模型 (訓練)
- 回測作業
- 預測作業
事前準備
如要查看及管理記錄，請確認您具備正確的 IAM 權限和角色。
平台記錄啟用狀態
AML AI 的平台記錄一律會啟用 (無法關閉)。
記錄嚴重性
AML AI 記錄項目使用三種嚴重性等級：
- 作業開始或成功時傳送的項目
NOTICE ERROR，瞭解作業失敗的相關項目INFO，瞭解作業進度
查看平台記錄
如要查看平台記錄，請按照下列步驟操作：
控制台
如要在 Google Cloud 控制台中查看平台記錄：
前往 Logs Explorer：
選取適當的 Google Cloud 專案。
在「Query」(查詢) 欄位中，輸入下列查詢指令：
logName=("projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fbacktest" OR "projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fengine_config_creation" OR "projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fmodel_creation" OR "projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fprediction")其中：
PROJECT_ID是您要偵錯或監控的專案 ID。例如：my-project。點選「執行查詢」。
如要進一步瞭解 Logs Explorer，請參閱「Logs Explorer 總覽」和「使用 Logs Explorer」。
gcloud
gcloud 指令列工具提供 Cloud Logging 的指令列介面。
如要查看專案的記錄，請執行下列指令：
gcloud logging read 'logName=("projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fbacktest" OR
"projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fengine_config_creation" OR
"projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fmodel_creation" OR
"projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fprediction")' --project=PROJECT_ID
其中 PROJECT_ID 是專案 ID。 Google Cloud

本節說明如何解讀 AML AI 的特定平台記錄。
START 記錄
作業開始執行時，系統會產生含有 eventKind=START 的記錄。
以下是啟動預測執行的記錄範例。
jsonPayload:

您可以在 Logs Explorer 的「Query」(查詢) 欄位中新增其他指令，縮小顯示的記錄範圍。
新增下列指令，顯示所選資料集的所有已啟動預測執行作業：
logName="projects/PROJECT_ID/logs/financialservices.googleapis.com%2Fprediction" AND jsonPayload.predictionResult.dataset="projects/PROJECT_ID/locations/REGION_ID/instances/INSTANCE_ID/datasets/DATASET_ID" AND jsonPayload.eventKind="START"
PROGRESS 記錄
含有 eventKind=PROGRESS 的記錄會提供作業進度資訊。
以下是建立模型的記錄範例。completedTaskCount 與 taskCount 可用於估算模型訓練的進度。
jsonPayload:
