## Amazon CloudWatch 可观察性访问管理器定义的操作
<a name="amazoncloudwatchobservabilityaccessmanager-actions-as-permissions"></a>

您可以在 IAM 策略语句的 `Action` 元素中指定以下操作。可以使用策略授予在 AWS中执行操作的权限。您在策略中使用一项操作时，通常使用相同的名称允许或拒绝对 API 操作或 CLI 命令的访问。但在某些情况下，单一动作可控制对多项操作的访问。还有某些操作需要多种不同的动作。

操作表的**访问级别**列描述如何对操作进行分类（列出、读取、权限管理或标记）。此分类可以帮助您了解当您在策略中使用操作时，相应操作授予的访问级别。有关访问级别的更多信息，请参阅[策略摘要中的访问级别](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_understand-policy-summary-access-level-summaries.html)。

操作表的**资源类型**列指示每项操作是否支持资源级权限。如果该列没有任何值，您必须在策略语句的 `Resource` 元素中指定策略应用的所有资源（“\*”）。通过在 IAM policy 中使用条件来筛选访问权限，以控制是否可以在资源或请求中使用特定标签键。如果操作具有一个或多个必需资源，则调用方必须具有使用这些资源来使用该操作的权限。必需资源在表中以星号 (\*) 表示。如果您在 IAM policy 中使用 `Resource` 元素限制资源访问权限，则必须为每种必需的资源类型添加 ARN 或模式。某些操作支持多种资源类型。如果资源类型是可选的（未指示为必需），则可以选择使用一种可选资源类型。

操作表的**条件键**列包括可以在策略语句的 `Condition` 元素中指定的键。有关与服务资源关联的条件键的更多信息，请参阅资源类型表的**条件键**列。

操作表的**依赖操作**列显示成功调用操作可能需要的其他权限。除了操作本身的权限以外，可能还需要这些权限。若某个操作指定依赖操作，则这些依赖关系可能适用于为该操作定义的其他资源，而不仅仅是表中列出的第一个资源。

**注意**  
资源条件键在[资源类型](#amazoncloudwatchobservabilityaccessmanager-resources-for-iam-policies)表中列出。您可以在操作表的**资源类型（\* 为必需）**列中找到应用于某项操作的资源类型的链接。资源类型表中的资源类型包括**条件密钥**列，这是应用于操作表中操作的资源条件键。

有关下表中各列的详细信息，请参阅[操作表](reference_policies_actions-resources-contextkeys.html#actions_table)。
