通过API查看监控 - 传统型负载均衡CLB| 阿里云

背景信息

通过API查看监控数据流程，如下图所示。

流程说明如下：

调用DescribeProjectMeta接口查询云监控中负载均衡的数据命名空间Namespace。
调用DescribeMetricMetaList接口查询云监控开放的时序类指标监控项描述或直接查看监控项说明，详情参见监控报警项说明。
查看监控项。
- 调用DescribeMetricLast接口查询负载均衡指定监控对象的最新监控数据。
- 调用DescribeMetricList接口查询负载均衡指定时间段内监控对象的时序指标监控数据。

本文以查询实例ID为lb-bp1r92vzpemy099*****，已配置七层监听的负载均衡实例的Qps监控项为例。

DescribeProjectMeta

调用DescribeProjectMeta接口查询云监控中负载均衡的数据命名空间Namespace，详情请参见DescribeProjectMeta。

将请求参数中报警产品标签过滤Labels的值设置为[{"name":"product","value":"SLB"}]，其他参数保持默认值。
请求示例：
```
http(s)://[Endpoint]/?Action=DescribeProjectMeta
&Labels=[{"name":"product","value":"SLB"}]
&<公共请求参数>
```

根据返回参数，获取云监控中负载均衡数据命名空间Namespace的值为acs_slb_dashboard。

返回示例：

{
    "PageSize": 30, 
    "RequestId": "75B895A2-62A4-411E-871C-0EED97CC0D26", 
    "PageNumber": 1, 
    "Total": 1, 
    "Resources": {
        "Resource": [
            {
                "Description": "负载均衡", 
                "Labels": "[{\"name\":\"product\",\"value\":\"SLB\"},{\"name\":\"productCategory\",\"value\":\"slb\"},{\"name\":\"groupFlag\",\"value\":\"true\"},{\"name\":\"cnName\",\"value\":\"负载均衡\"},{\"name\":\"enName\",\"value\":\"Server Load Balancer\"}]", 
                "Namespace": "acs_slb_dashboard"
            }
        ]
    }, 
    "Code": 200, 
    "Success": true
}

DescribeMetricMetaList

调用DescribeMetricMetaList接口查询云监控开放的时序类指标监控项描述，详情请参见DescribeMetricMetaList。

将请求参数中数据命名空间Namespace的值设置为acs_slb_dashboard，其他参数保持默认值。
请求示例：
```
http(s)://[Endpoint]/?Action=DescribeMetricMetaList
&Namespace=acs_slb_dashboard
&<公共请求参数>
```

根据返回参数，查看负载均衡的时序类指标监控项。可以查看本次示例中使用的监控项Qps是否存在。

返回示例：

DescribeMetricLast

调用DescribeMetricLast接口查询负载均衡指定监控对象的最新监控数据，本示例查看七层协议Qps的最新监控数据，详情请参见DescribeMetricLast。

四层和七层协议的监控项和监控指标不同，详情请参见监控报警项说明。

在请求参数中，设置查询Qps的参数。
需要配置以下参数，其他参数可保持默认值。
- MetricName：监控项名称，本示例设置为Qps。
- Dimensions：维度map，用于查询指定资源的监控数据，本示例设置为[{"instanceId":"lb-bp1r92vzpemy099f******"}]。
- Namespace：产品的数据命名空间，用于区分不同的产品，本示例设置为acs_slb_dashboard。
请求示例：
```
http(s)://[Endpoint]/?Action=DescribeMetricLast
&MetricName=Qps
&Namespace=acs_slb_dashboard
&Dimensions=[{"instanceId":"lb-bp1r92vzpemy099f******"}]
&<公共请求参数>
```

根据返回参数，查看Qps的最新监控数据。

返回示例：

{
    "RequestId": "B0EED5A2-7FE2-4A0C-B5E9-3D961F86DC9D", 
    "Period": "60", 
    "Datapoints": "[{\"timestamp\":1586248680000,\"userId\":\"16884015959*****\",\"instanceId\":\"lb-bp1r92vzpemy099f*****\",\"port\":\"80\",\"protocol\":\"http\",\"vip\":\"121.43.**.**\",\"Average\":0}]", 
    "Code": "200", 
    "Success": true
}

DescribeMetricList

调用DescribeMetricList接口查询负载均衡指定时间段内的时序指标监控数据，详情请参见DescribeMetricList。

在请求参数中，设置查询指定时间内Qps的监控数据。
需要配置以下参数，其他参数可保持默认值。
- MetricName：监控项名称，本次示例设置为Qps。
- Namespace：产品的数据命名空间，用于区分不同的产品，本次示例设置为acs_slb_dashboard。
- Dimensions：维度map，用于查询指定资源的监控数据，本示例设置为[{"instanceId":"lb-bp1r92vzpemy099f******"}]。
- StartTime：开始时间，StartTime不能等于或大于EndTime，本次示例设置为2020-03-28 00:10:00。
  支持格式：
  - Unix时间戳：从1970年1月1日开始所经过的秒数。
  - Format格式：YYYY-MM-DDThh:mm:ssZ。
- EndTime：结束时间，支持的格式和StartTime一致，本次示例设置为2020-03-28 00:11:00。
请求示例：
```
http(s)://[Endpoint]/?Action=DescribeMetricList
&MetricName=Qps
&Namespace=acs_slb_dashboard
&Dimensions=[{"instanceId":"lb-bp1r92vzpemy099f******"}]
&StartTime=2020-03-28 00:10:00
&EndTime=2020-03-28 00:11:00
&<公共请求参数>
```

根据返回参数，查看Qps在指定时间内的监控数据。

返回示例：

{
    "RequestId": "DFF0A853-0E37-4108-A9AF-5B3D609BD489", 
    "Period": "60", 
    "Datapoints": "[{\"timestamp\":1585325460000,\"userId\":\"168840159596****\",\"instanceId\":\"lb-bp1r92vzpemy099f******\",\"port\":\"80\",\"protocol\":\"http\",\"vip\":\"121.43.**.**\",\"Average\":0}]", 
    "Code": "200", 
    "Success": true
}
