介绍如何通过云监控Java和Python SDK查看负载均衡实例的监控项和详细监控数据。
前提条件
背景信息
通过SDK查看监控数据API使用流程，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。
- 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。
Python
示例：查询实例ID为lb-f8zbff0i07sv4qr1****，已配置七层监听的负载均衡实例的QPS监控项。
Python SDK代码如下：
from aliyunsdkcms.request.v20190101 import DescribeProjectMetaRequest, DescribeMetricMetaListRequest, \
DescribeMetricLastRequest, DescribeMetricListRequest
from aliyunsdkcore.client import AcsClient
import json
if __name__ == '__main__':
# 1.初始化SDK

'VRj7d6LOl2ZyFyfYTWYzGk0*****', # your-access-key-secret
'cn-heyuan', # your-region-id
)
# 过滤标签，此处过滤产品名称为SLB的数据
labels = "[{\"name\":\"product\",\"value\":\"SLB\"}]"
# 监控维度，此处查询后端服务器实例的监控数据
dimensions = "[{\"instanceId\":\"lb-f8zbff0i07sv4qr1******\"}]"
# 指定查询时间段，根据需要自行替换
startTime = "2020-04-08 11:39:30"
endTime = "2020-04-08 11:50:30"
# 监控数据时间间隔
period = "60"
# 2.调用DescribeProjectMeta接口查询SLB的Namespace
describeProjectMetaRequest = DescribeProjectMetaRequest.DescribeProjectMetaRequest()
describeProjectMetaRequest.set_Labels(labels)
describeProjectMetaResponse = ACS_CLIENT.do_action_with_exception(describeProjectMetaRequest)
describeProjectMetaResponse_json = json.loads(describeProjectMetaResponse)

# 3.调用DescribeMetricMetaList接口查询SLB可用的云监控时序类指标监控项
describeMetricMetaListRequest = DescribeMetricMetaListRequest.DescribeMetricMetaListRequest()

metricMetaListResources = describeMetricMetaListResponse_json['Resources']['Resource']
print(metricMetaListResources)
# 这里以查询此监控项为例：ActiveConnection（端口当前活跃连接数）
metricName = "Qps" #设置监控项
# 4.查询指定监控项的最新监控数据
describeMetricLastRequest = DescribeMetricLastRequest.DescribeMetricLastRequest()
describeMetricLastRequest.set_Namespace(namespace)
describeMetricLastRequest.set_MetricName(metricName)
describeMetricLastRequest.set_Dimensions(dimensions)
describeMetricLastRequest.set_Period(period)
describeMetricLastResponse = ACS_CLIENT.do_action_with_exception(describeMetricLastRequest)
describeMetricLastResponse_json = json.loads(describeMetricLastResponse)
print("最新监控数据：\n", describeMetricLastResponse_json['Datapoints'])
# 5.查询指定时间段内的指定监控项数据
describeMetricListRequest = DescribeMetricListRequest.DescribeMetricListRequest()
describeMetricListRequest.set_Namespace(namespace)
describeMetricListRequest.set_MetricName(metricName)
describeMetricListRequest.set_Dimensions(dimensions)
describeMetricListRequest.set_Period(period)
describeMetricListRequest.set_StartTime(startTime)
describeMetricListRequest.set_EndTime(endTime)
describeMetricListResponse = ACS_CLIENT.do_action_with_exception(describeMetricListRequest)

print("指定时间段的监控数据：\n", describeMetricListResponse_json['Datapoints'])
