# CloudWatch 亚马逊 VPC Lattice 的指标
<a name="monitoring-cloudwatch"></a>

Amazon VPC Lattice 将与您的目标群体和服务相关的数据发送到亚马逊 CloudWatch，并将其处理为可读的近乎实时的指标。这些指标会保留 15 个月，使您能够访问历史信息，并更好地了解您的 Web 应用程序或服务的执行情况。此外，可以设置用于监测特定阈值的警报，并在达到相应阈值时发送通知或执行操作。有关更多信息，请参阅 [Amazon CloudWatch 用户指南](https://docs.aws.amazon.com//AmazonCloudWatch/latest/monitoring/WhatIsCloudWatch.html)。

Amazon VPC Lattice 使用您 AWS 账户中的服务相关角色向亚马逊发送指标。 CloudWatch有关更多信息，请参阅 [使用适用于 Amazon VPC 莱迪思的服务相关角色](using-service-linked-roles.md)。

## 查看 Amazon CloudWatch 指标
<a name="monitoring-cloudwatch-view"></a>

您可以使用 CloudWatch 控制台或查看目标群体和服务的Amazon CloudWatch 指标 AWS CLI。

**使用 CloudWatch 控制台查看指标**

1. 打开 Amazon CloudWatch 控制台，网址为[https://console.aws.amazon.com/cloudwatch/](https://console.aws.amazon.com/cloudwatch/)。

1. 在导航窗格中，选择**指标**。

1. 选择 `AWS/VpcLattice` 命名空间。

1. （可选）要跨所有维度查看某个指标，请在搜索字段中输入其名称。

1. (可选) 要按维度筛选，请选择下列选项之一：
   + 要仅显示为目标组报告的指标，请选择**目标组**。要查看单个目标组的指标，请在搜索字段中输入其名称。
   + 要仅显示为服务报告的指标，请选择**服务**。要查看单个服务的指标，请在搜索字段中输入其名称。

**要查看指标，请使用 AWS CLI**

使用以下 [CloudWatch list-Metrics AWS CLI 命令列出可用指标](https://docs.aws.amazon.com/cli/latest/reference/cloudwatch/list-metrics.html)：

`aws cloudwatch list-metrics --namespace AWS/VpcLattice`

有关每个指标及其维度的信息，请参阅 [目标组指标](#monitoring-cloudwatch-tg) 和 [服务指标](#monitoring-cloudwatch-service)。
