查看执行步骤的历史记录

您可以检索指定工作流执行的历史记录,即 step 条目。每个步骤条目都提供的信息可帮助您分析、调试或优化工作流。例如,您可以确认 并确定步骤的持续时间和成功与否。 在调试大型或 非线性工作流(例如,具有多个并行分支的工作流)。

步骤条目表示源代码中的实际步骤(例如 assigncall)或指令块(例如 for 循环或 try/retry/except 块)。如需查看步数类型的完整列表,请参阅 StepType

如何检索步骤条目

您可以通过向 Workflow Executions REST API 发送请求或通过 Google Cloud 控制台检索步骤条目:

  • Google Cloud 控制台 - 在本文档中,请参阅 在控制台中查看步骤条目

    除了列出步骤条目及其详细信息之外,控制台还会以图形方式显示执行步骤,以便您更轻松地查看和分析工作流执行路径。

  • Workflow Executions REST API - 在本文档中,请参阅 检索步骤条目列出步骤条目

步骤条目信息

步骤条目包含以下信息。有关详情, 文档,请参阅示例

名称 步骤条目的完整资源名称,它是具有 格式,其中 STEPENTRY_ID 为 增加计数器:
projects/PROJECT_NUMBER/locations/LOCATION/workflows/WORKFLOW_ID/executions/EXECUTION_ID/stepEntries/STEPENTRY_ID
例如:
projects/123456789012/locations/us-central1/workflows/myFirstWorkflow/executions/ae8a66a1-cefa-4d16-8a2f-d50c712d8ef1/stepEntries/2
创建和更新时间 步骤条目的创建时间和最近一次更新的时间戳。如果步骤条目已完成,updateTime 会指示完成时间。
日常安排和步骤名称 步骤条目所属的例程和步骤的名称。答 例程名称是在 YAML 或 JSON 源中定义的子工作流名称 代码。顶级例程名称为 main
状态和进度类型 步骤条目的状态,例如条目是成功还是失败,或者步骤条目是否正在进行以及进度类型。如需查看状态和进度类型的完整列表,请参阅 StateProgressType
导航信息 步骤条目的位置,以便您更好地了解工作流的层次结构和流程,例如,当前步骤条目前面或后面是哪些步骤条目,或者哪些是步骤条目的父级或子级。如需了解详情,请参阅 NavigationInfo
元数据 与迭代步骤条目相关的数据,其中包括 表示子线程(例如, STEP_PARALLEL_BRANCH_ENTRY 英寸 STEP_PARALLEL_BRANCH)或 for 的迭代 (例如,STEP_FOR_ITERATION 中的 STEP_FOR)。有关详情,请参阅 StepEntryMetadata
例外情况 与任何异常相关的载荷,其中说明了步骤条目失败的原因。

在控制台中查看步骤条目

您可以在 Google Cloud 控制台。

  1. 在 Google Cloud 控制台中,进入 Workflows 页面:

    进入 Workflows

  2. 点击该工作流的名称,以转到其工作流详情页面。

  3. 如需了解特定执行的详细信息,请点击其执行 ID。

    摘要标签页提供关于总体执行的信息, 包括任何导致执行失败的异常。如需了解详情,请参阅执行错误消息

  4. 如需将工作流执行记录视为步骤条目列表进行查看,请点击步骤标签页。

    系统会列出工作流执行的所有步骤条目。

  5. 如需过滤步骤条目,请使用表格顶部的过滤条件字段选择一个属性和一个值(例如 State: Failed)。

  6. 如需显示任何父级子级下一步上一步步骤条目的链接,请点击相应步骤条目。

    如果您点击某个链接,其他链接会自动更新。例如: 父级将链接到您点击的步骤条目的父级。

  7. 可视化面板以图形方式显示工作流中的步骤,并帮助您了解工作流路径。

    可视化面板示例

    点击图表可将其放大:

    显示包含失败步骤的工作流的可视化面板

    请注意,可视化图表可能与步骤条目不同。例如,for 块在可视化中显示为单个组件;但是,根据迭代次数,可能有多个步骤条目。

    您可以在面板中执行以下操作:

    • 放大或缩小可视化图表
    • 收起或展开父级步骤条目
    • 点击某个步骤条目,查看其前后条目
    • 确认成功和失败的步骤条目(以绿色对勾标记表示) 或红色感叹号
    • 点击 展开箭头关闭可视化面板;再次点击该箭头可打开该面板

检索步骤条目前的准备工作

如需获得检索步骤条目所需的权限,请让您的管理员为您授予项目的 Workflows Admin (workflows.stepEntries.get) IAM 角色。 如需详细了解如何授予角色,请参阅管理对项目、文件夹和组织的访问权限

您也可以通过自定义角色或其他预定义角色来获取所需的权限。

检索步骤条目

要检索指定工作流执行的步骤条目,请使用 projects.locations.workflows.executions.stepEntries.get 方法。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_NUMBERIAM 和管理设置页面中列出的 Google Cloud 项目编号。
  • LOCATION:在其中部署此工作流的区域,例如 us-central1
  • WORKFLOW_ID:工作流的用户定义名称,例如 myFirstWorkflow
  • EXECUTION_ID:工作流执行的唯一 ID,在工作流执行后返回。
  • STEPENTRY_ID:步骤条目的唯一 ID,例如 1

如需发送您的请求,请展开以下选项之一:

您应该收到类似以下内容的 JSON 响应:

}

列出步骤条目之前

如需获得列出步骤条目所需的权限,请让管理员向您授予项目的 Workflows Admin (workflows.stepEntries.list) IAM 角色。 如需详细了解如何授予角色,请参阅管理对项目、文件夹和组织的访问权限

您也可以通过自定义角色或其他预定义角色来获取所需的权限。

列出步骤条目

要列出给定工作流执行的步骤条目,请使用 projects.locations.workflows.executions.stepEntries.list 方法。默认情况下,系统会按步骤条目的 createTime 升序返回结果。

在使用任何请求数据之前,请先进行以下替换:

  • PROJECT_NUMBER:您的 Google Cloud 项目编号,IAM 和管理 设置页面。
  • LOCATION: 部署工作流的区域,例如 us-central1
  • WORKFLOW_ID:工作流的用户定义名称,例如 myFirstWorkflow
  • EXECUTION_ID: 工作流执行作业。
