AWS RDS 度量集

AWS 模块的 rds 度量集允许您监控您的 AWS RDS 服务。rds 度量集从 Amazon RDS 和 Amazon Aurora DB 获取一组指标。使用 Amazon RDS，用户可以监控其数据库实例的网络吞吐量、读写和/或元数据操作的 I/O、客户端连接以及突发信用余额。Amazon RDS 每分钟将指标和维度发送到 Amazon CloudWatch。Amazon Aurora 提供各种 Amazon CloudWatch 指标，用户可以使用这些指标来监控其 Aurora DB 集群的运行状况和性能。此度量集默认情况下会收集来自 AWS RDS 的所有标签。

AWS 权限

编辑

IAM 用户需要一些特定的 AWS 权限才能收集 AWS RDS 指标。

cloudwatch:GetMetricData
ec2:DescribeRegions
rds:DescribeDBInstances
rds:ListTagsForResource
sts:GetCallerIdentity
iam:ListAccountAliases

仪表盘

编辑

aws rds 度量集带有一个预定义的仪表盘。

配置示例

编辑

- module: aws
  period: 60s
  metricsets:
    - rds
  access_key_id: '<access_key_id>'
  secret_access_key: '<secret_access_key>'
  session_token: '<session_token>'

这是一个默认的度量集。如果主机模块未配置，则默认启用此度量集。
