容器服务 Kubernetes 版 ACK:通过Cost API获取成本数据

更新时间:Mar 29, 2024

您可以通过Cost API查询集群指定命名空间或Pod在指定时间周期内的实时估算成本和资源监控数据。

前提条件

已参见通过API获取成本数据概述完成准备工作。

成本数据导出命令

连接集群后,您可以执行命令获取成本数据。获取成本数据的命令参数如下。

参数

描述

DimensionType

成本统计维度,默认为集群下所有Pod。取值:

  • Namespace:按照命名空间维度获取应用的成本。

  • Pod:按照Pod维度获取应用的成本。

Dimension

成本筛选值,若填写即指定请求某个维度值。

  • 当设置DimensionType为Namespace时,存在以下情况。

    • 若不填写Dimension,将返回所有命名空间的成本数据。

    • 若设置为Dimension=A Namespace时,则只返回A命名空间的成本数据。

    • 若设置LabelSelector,则会返回LabelSelector筛选后的数据。

  • 当设置DimensionType为Pod时,存在以下情况。

    • 若不填写Dimension,将返回所有Pod的成本数据。

    • 若设置为Dimension=A Pod时,则只返回A Pod的成本数据。

      说明

      您也可以选择多个Pod,使用英文半角逗号(,)隔开,例如Dimension=pod=node-exporter-7vtmj,pod=node-exporter-cn54q

    • 若设置LabelSelector,则会返回LabelSelector筛选后的数据。

LabelSelector

通过应用(app)标签筛选Pod,获取筛选后的成本数据。

TimeUnit

成本数据统计时间。可选值包括hourdayweekmonth,默认为hour

Summary

设置为true时,将返回筛选后的Pod数据总和。默认为false

成本数据指标

  • cpu:单位为核。

  • gpu:单位为卡。

  • memory:单位为KB。

  • perCorePricing:当前Pod或所查询应用所在的节点的单位CPU核的价格,中国站单位为¥,国际站单位为$。

  • costRatio:当前Pod或所查询应用占整个集群成本比例,例如值为0.2时,表明所选应用的成本占总集群成本的20%。

  • cost:当前Pod或所查询应用在查询时间范围内的成本,中国站单位为¥,国际站单位为$。

  • customCost:当前Pod或所查询应用在查询时间范围内的定价成本。
