在Amazon Cloudwatch Insights中，您如何获取统计数据？

Question

我正在使用AWS Cloudwatch Insights并运行如下查询：

public function scopeTopFeatures(Builder $query, $topFeatureIds): Builder
{
    return $query->whereHas('features', function (Builder $query) use ($topFeatureIds) {
        $query->whereIn('vehicle_feature_id', $topFeatureIds);
    });
}

但是，在最后一行，出现以下错误：

fields @message, @timestamp
| filter strcontains(@message, "Something of interest happened")
| stats count() as interestCount by bin(10m) as tenMinuteTime
| stats max(interestCount) by datefloor(tenMinuteTime, 1d)

由此看来，这意味着我无法在Insights中进行多层统计查询，因此无法进行统计。有办法解决吗？

Answer 1

您当前无法使用多个stat命令，据我所知，目前尚无直接方法。但是，您可以加厚单个stat命令并以逗号分隔，如下所示：

您定义字段并在fields @message, @timestamp | filter strcontains(@message, "Something of interest happened") | stats count() as @interestCount, max(interestCount) as @maxInterest, interestCount by bin(10m) as @tenMinuteTime 之后使用函数，然后处理这些结果字段。
