本页介绍了如何使用由 AML AI 生成的平台日志
作为 Cloud Logging 的一部分。AML AI 使用 Logging
API 服务名称 financialservices.googleapis.com，用于记录以下活动：
- 引擎配置创建（调优）
- 模型创建（训练）
- 回测操作
- 预测操作
准备工作
要查看和管理日志，请确保您拥有正确的 IAM 权限和角色。
平台日志记录的启用状态
AML AI 的平台日志始终处于活动状态（无法关闭）。
日志严重性
AML AI 日志条目使用三个严重级别：
NOTICE（针对操作开始或成功时发送的条目）ERROR（针对有关结束操作结束的条目）INFO（适用于与操作进度相关的条目）
查看平台日志
如需查看平台日志，请按照以下说明操作：
控制台
如需在 Google Cloud 控制台中查看平台日志，请执行以下操作：
导航到日志浏览器：
选择相应的 Google Cloud 项目。
在查询字段中，输入以下查询命令：
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是要调试或监控的项目的 ID。例如my-project。点击运行查询。
gcloud
gcloud 命令行工具提供了用于 Cloud Logging 的命令行界面。
如需查看项目的日志，请运行以下命令：
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 是您的 Google Cloud 项目的 ID。
如需详细了解如何将 gcloud 工具与 Cloud Logging 搭配使用，请参阅
gcloud logging。
了解平台日志
本部分介绍如何了解特定平台日志， AML AI。
START 日志
操作开始执行时，系统会生成包含 eventKind=START 的日志。
以下是开始运行预测运行的日志示例。
jsonPayload:
'@type': type.googleapis.com/google.cloud.financialservices.logging.v1.PredictionLog
engineVersion: projects/PROJECT_ID/locations/REGION_ID/instances/INSTANCE_ID/engineVersions/ENGINE_VERSION_ID

您可以在 Logs Explorer 的查询字段中添加其他命令，以缩小显示的日志范围。
添加以下命令可显示所选数据集上已开始的所有预测运行：
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 日志
包含 eventKind=PROGRESS 的日志用于提供操作进度信息。
以下是创建模型的日志示例。completedTaskCount对阵taskCount
可用于估算模型训练的进度。
jsonPayload:
'@type': type.googleapis.com/google.cloud.financialservices.logging.v1.ModelCreationLog

结束日志
操作结束时，系统会生成包含 eventKind=END 的日志。
以下是失败的引擎配置创建日志示例。 它包含有关提供的数据集中错误数据的错误。
