amazon-web-services - CloudWatch 统一代理 : Additional property append_dimensions is not allowed

Question

我正在尝试向发布到 cloudwatch 统一代理的 statsd 指标添加自定义维度。 CW 文档指出 append_dimensions下metrics部分仅支持InstanceId , InstanceType , AutoScalingGroupName并无视他人。

CloudWatch 代理配置文件:指标部分:

Docs

append_dimensions – Optional. Adds Amazon EC2 metric dimensions to all metrics collected by the agent. The only supported key-value pairs are shown in the following list. Any other key-value pairs are ignored.

"ImageID":"${aws:ImageId}" sets the instance's AMI ID as the value of the ImageID dimension.

"InstanceId":"${aws:InstanceId}" sets the instance's instance ID as the value of the InstanceID >

dimension.

"InstanceType":"${aws:InstanceType}" sets the instance's instance type as the value of the > InstanceType dimension.

"AutoScalingGroupName":"${aws:AutoScalingGroupName}" sets the instance's Auto Scaling group name > as the value of the AutoScalingGroupName dimension.

文档建议添加 append_dimensions直接转到定义您希望使用自定义维度的指标的部分。

向 CloudWatch 代理收集的指标添加自定义维度 :

Docs

To add custom dimensions such as tags to metrics collected by the agent, add the append_dimensions field to the section of the agent configuration file that lists those metrics.

所以我尝试添加 append_dimensions到 statsd部分:

"statsd": {
  "service_address": ":8125",
  "metrics_collection_interval": 10,
  "metrics_aggregation_interval": 60,
  "append_dimensions": {
    "Environment": "${APP_ENV}"
  }
}

我得到错误:

Additional property append_dimensions is not allowed

我也尝试使用我的指标发送标签，但它们似乎被忽略了。

Answer 1

AWS 文档说“在运行 Linux 或 Windows Server 的服务器上，指标部分包括以下字段:... append_dimensions”和“如果您想将维度附加到具有任意键值对的指标，请在特定类型指标的字段。”

因此，您只能在指标部分或任何特定指标字段中添加 append_dimensions。

Retrieve Custom Metrics with StatsD说“您可以根据需要将三个可选字段添加到代理配置文件的 statsd 部分”，因此很明显 statsd 不支持 append_dimensions。
