如何将 DynamoDB 监控指标获取到 InfluxDB

Question

我正在构建一个监控管道，有没有人尝试在没有在 EC2/Lambda 中运行自定义代码的情况下将 DynamoDB 监控指标导入 InfluxDB。有没有插件可以解决这个问题？

如果你有什么好主意或者可以推荐一个插件，请与我分享。

Answer 1

是的，您可以使用以下方法将 DynamoDB 矩阵从 AWS 拉到 InfluxDB Telegraf图书馆。

Telegraf 是一个用 Go 编写的代理，用于收集、处理、 汇总和编写指标。

注意：您不需要在 EC2/Lambda 中运行自定义代码。

根据Issue Raised for : influxdata/telegraf

以下是最终在 InfluxDB 中出现的指标：

cloudwatch_aws_efs
cloudwatch_aws_elastic_beanstalk
cloudwatch_aws_elb
cloudwatch_aws_lambda
cloudwatch_aws_rds

另外，根据https://github.com/influxdata/telegraf/issues/1907#issuecomment-258270588

AWS 账户中默认不启用 AutoScaling 指标。

您是否为某些 ASG 启用了它们？

关注： http://docs.aws.amazon.com/autoscaling/latest/userguide/as-instance-monitoring.html#as-enable-group-metrics

如果您没有为任何 ASG 启用它们，则 cloudwatch 会返回一个空的可用于 AWS/AutoScaling 命名空间的指标列表。
