AWS CloudWatch 度量集
编辑AWS CloudWatch 度量集编辑
AWS 模块的 CloudWatch 度量集允许您监控 AWS 上的各种服务。 cloudwatch 度量集通过调用 GetMetricData API 定期从给定命名空间获取度量指标。
AWS 权限编辑
IAM 用户需要一些特定的 AWS 权限才能收集 AWS CloudWatch 度量指标。
ec2:DescribeRegions cloudwatch:GetMetricData cloudwatch:ListMetrics tag:getResources sts:GetCallerIdentity iam:ListAccountAliases
度量集特定配置说明编辑
- 命名空间: ListMetrics API 用于过滤的命名空间。例如，AWS/EC2、AWS/S3。如果将通配符 * 指定为命名空间，则将自动收集来自所有命名空间的度量指标。
- 名称: 要过滤的度量指标的名称。例如，EC2 实例的 CPUUtilization。
- 维度: 要过滤的维度。例如，InstanceId=i-123。
- 资源类型: 您希望返回的资源的约束。每个资源类型的格式为 service[:resourceType]。例如，指定资源类型 ec2 将返回所有 Amazon EC2 资源（包括 EC2 实例）。指定资源类型 ec2:instance 只返回 EC2 实例。
- 统计: 统计是针对特定时间段内汇总的度量指标数据。默认情况下，统计包含平均值、总和、计数、最大值和最小值。
配置示例编辑
为了更专注于 cloudwatch 度量集的使用案例，以下示例不包含有关 AWS 凭据的配置。有关在配置中设置 AWS 凭据以使此度量集能够进行正确的 AWS API 调用的更多详细信息，请参阅 AWS 凭据选项。
示例 1编辑
- module: aws
period: 300s
metricsets:
- cloudwatch
tags_filter:
- key: "Organization"
value: "Engineering"
metrics:
- namespace: AWS/EBS
- namespace: AWS/ELB
resource_type: elasticloadbalancing
- namespace: AWS/EC2
name: CPUUtilization
statistic: ["Average"]
dimensions:
- name: InstanceId
value: i-0686946e22cf9494a

示例 2编辑
- module: aws
period: 300s
metricsets:
- cloudwatch
metrics:
- namespace: "*"
使用此配置，将从 CloudWatch 收集来自所有命名空间的度量指标。此处的限制是所有命名空间的收集周期都设置为相同，在本例中为 300 秒。这将导致 API 调用产生额外成本或数据丢失。例如，来自命名空间 AWS/Usage 的度量指标每分钟发送到 CloudWatch。如果收集周期等于 300 秒，则介于两者之间的数据点将丢失。来自命名空间 AWS/Billing 的度量指标每隔几个小时发送到 CloudWatch。通过每 300 秒从 AWS/Billing 命名空间查询，将产生额外成本。
示例 3编辑
根据配置和 AWS 帐户中的服务数量，API 调用的数量可能太大，从而导致 API 成本过高。为了减少 API 调用的数量，建议用户使用以下配置作为示例。
- metrics.name: 只收集对您的使用案例有用的度量指标子列表。
- metrics.statistic: 默认情况下，CloudWatch 度量集将进行 API 调用以获取所有统计数据，例如平均值、最大值、最小值、总和等。如果用户知道哪种统计方法最有用，请在配置中指定它。
-
metrics.dimensions: 不同的 AWS 服务在 CloudWatch 度量指标中报告不同的维度。例如，EMR 度量指标 可以具有
JobFlowId维度或JobId维度。如果用户知道哪个特定维度有用，则可以在此配置选项中指定它。
- module: aws
period: 5m
metricsets:
- cloudwatch
regions: us-east-1
metrics:
- namespace: AWS/ElasticMapReduce
name: ["S3BytesWritten", "S3BytesRead", "HDFSUtilization", "TotalLoad"]
resource_type: elasticmapreduce
statistic: ["Average"]
dimensions:
- name: JobId
value: "*"

使用以下配置，用户将能够从 EBS、ELB 和 EC2 收集 CloudWatch 度量指标，而无需标签信息。
- module: aws
period: 300s
metricsets:
- cloudwatch
metrics:
- namespace: AWS/EBS
- namespace: AWS/ELB
- namespace: AWS/EC2
使用以下配置，用户将能够从 EBS、ELB 和 EC2 收集 CloudWatch 度量指标以及来自这些服务的标签。
- module: aws
period: 300s
metricsets:
- cloudwatch
metrics:
- namespace: AWS/EBS
resource_type: ebs
- namespace: AWS/ELB
resource_type: elasticloadbalancing
- namespace: AWS/EC2
resource_type: ec2:instance
使用以下配置，用户将能够收集特定的 CloudWatch 度量指标。例如，来自 EC2 实例 i-123 的 CPUUtilization 度量指标（平均值）和来自 EC2 实例 i-456 的 NetworkIn 度量指标（平均值）。
- module: aws
period: 300s
metricsets:
- cloudwatch
metrics:
- namespace: AWS/EC2
name: ["CPUUtilization"]
resource_type: ec2:instance
dimensions:
- name: InstanceId
value: i-123
statistic: ["Average"]
- namespace: AWS/EC2
name: ["NetworkIn"]
dimensions:
- name: InstanceId
value: i-456
statistic: ["Average"]
使用以下配置，用户可以仅筛选出具有度量指标名称 UnHealthyHostCount 的 LoadBalacer 和 TargetGroup 维度度量指标，LoadBalacer 和 TargetGroup 值可以是任何值。
- module: aws
period: 300s
metricsets:
- cloudwatch
metrics:
- namespace: AWS/ApplicationELB
statistic: ['Maximum']
name: ['UnHealthyHostCount']
dimensions:
- name: LoadBalancer
value: "*"
- name: TargetGroup
value: "*"
resource_type: elasticloadbalancing
这是一个默认的度量集。如果未配置主机模块，则默认情况下启用此度量集。
