Question

我想使用 datadog 的异常值检测来检测错误/错误的 aws 实例。那可能吗？我正在尝试使用 datadog 创建一个自动故障转移方案。任何建议，将不胜感激。

You could use Datadog's Outlier detection to identify instances which exhibit behavior outside the normal for it's peer set. As an example, you could create an outlier detection monitor:

http://docs.datadoghq.com/guides/outliers/#alerts

Which would be scoped to a system metric like aws.ec2.cpuutilization and be alerted if any host spiked abnormally or had very low utilization in comparison to its group.

There are some additional blog posts which discuss the use of the algorithms that can be found here:

That said, if you find yourself needing additional assistance with outlier detection you can always reach out to the Support team at support@datadoghq.com or by using the internal support features found here:

Hope this helps!
