Zabbix 5.0:监控阿里云RDS
Blog:博客园 个人
由于近期压测,需要频繁登录阿里云查看RDS监控,每次登录查看监控步骤较为繁琐,故将监控接入到zabbix。
概述
由于阿里云已做了RDS的监控,我们只需要通过阿里云SDK把这些监控数据传输到zabbix即可。
前提
子账号
使用阿里云SDK需要一个AK,申请方式如下:
-
打开RAM 访问控制 (aliyun.com),创建子账号,选择Open api调用方式;
-
得到
AccessKey ID
和AccessKey Secret
;
- 添加
AliyunCloudMonitorReadOnlyAccess
权限;
环境
- Python版本:Python3
- SDK:aliyun-python-sdk-core、aliyun-python-sdk-cms
调用Api示例
Api:DescribeMetricTop
- Namespace为acs_rds_dashboard。
- Period默认为60秒,也可以为60的整数倍。
当前云产品的MetricName和Dimensions的取值如下表所示。

脚本示例:
#!/usr/bin/env python3
#coding=utf-8
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkcore.auth.credentials import AccessKeyCredential
from aliyunsdkcore.auth.credentials import StsTokenCredential
from aliyunsdkcms.request.v20190101.DescribeMetricTopRequest import DescribeMetricTopRequest
credentials = AccessKeyCredential('<your-access-key-id>', '<your-access-key-secret>')
# use STS Token
# credentials = StsTokenCredential('<your-access-key-id>', '<your-access-key-secret>', '<your-sts-token>')
client = AcsClient(region_id='cn-hangzhou', credential=credentials)
request = DescribeMetricTopRequest()
request.set_accept_format('json')
request.set_Namespace("acs_rds_dashboard")
request.set_MetricName("CpuUsage")
request.set_Orderby("Maximum")
request.set_Dimensions("[{\"instanceId\":\"rm-b*****qc\"}]")
response = client.do_action_with_exception(request)
# python2: print(response)
print(str(response, encoding='utf-8'))
输出结果如下:
{
"RequestId": "D0237455-0978-532A-AG95-C1DG8CD83346",
"Period": "60",
"Datapoints": "[{\"order\":1,\"timestamp\":1635413400000,\"userId\":\"186XXXXXXX\",\"instanceId\":\"rm-b*****c\",\"Maximum\":14.95,\"Minimum\":14.95,\"Average\":14.95,\"_count\":1.0}]",
"Code": "200"
}
配置模板
通过以上示例,很容易通过脚本得到相关监控数据。
脚本完成后,再导入模板,监控项如下:
