查询指标

功能介绍

该接口用于查询系统当前可监控的指标列表，可以指定指标命名空间、指标名称、维度、所属资源的编号（格式为：resType_resId），分页查询的起始位置和返回的最大记录条数。

调用方法

请参见如何调用API。

URI

POST /v1/{project_id}/ams/metrics

表1 路径参数

参数

是否必选

参数类型

描述

project_id

是

String

租户从IAM申请到的projectid，一般为32位字符串。
表2 Query参数

参数

是否必选

参数类型

描述

type

否

String

指标查询方式。

limit

否

String

用于限制本次返回的结果数据条数。

取值范围(0,1000]，默认值为1000。

最小长度：0

最大长度：4

start

否

String

分页查询起始位置，为非负整数。

请求参数

表3 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

是

String

从IAM服务获取的用户Token。

Content-Type

是

String

指定类型为application/json。

枚举值：

  • application/json
表4 请求Body参数

参数

是否必选

参数类型

描述

inventoryId

否

String

资源编号，格式为resType_resId。其中resType部分的枚举值为：host，application，instance， container，process，network，storage， volume。当URI参数中的type取值为“inventory”时，通过该参数查询关联的指标，不再使用metricItems数组中的信息。

metricItems

否

Array of QueryMetricItemOptionParam objects

当URI参数中的type取值不为“inventory”时，就通过该数组传递的参数信息进行指标查询。
