如何使 Application Insights kusto 查询在 performanceBucket 上正确排序？

Question

有没有办法让 Application Insights kusto 查询按 performanceBucket 'correctly' 排序，即按存储桶持续时间排序？当我使用 performanceBucket 进行总结或排序并且未指定排序时，我得到类似这样的结果（例如，请注意 1-3sec 与 3-7sec 不相邻）：

如果我按 performanceBucket 添加排序，则按字母数字顺序完成：

我希望按此顺序（或相反）

<250 毫秒
250ms-500ms
500 毫秒-1 秒
1sec-3sec
3sec-7sec
7sec-15sec
15sec-30sec
30秒-1分钟
1min-2min

Answer 1

您需要人为添加一个表示您喜欢的排序顺序的列，然后按它排序，然后投影出去：

// Synthetic data - don't copy this
let YourResult = datatable(perfBucket:string, count_:long) [
    "250ms-500ms", 14000,
    "7sec-15sec", 600,
    "1sec-3sec", 9700
];
// This is the actual query
YourResult
| extend sortOrder =
    case(perfBucket == "<250ms", 1,
         perfBucket == "250ms-500ms", 2,
         perfBucket == "500ms-1sec", 3,
         perfBucket == "1sec-3sec", 4,
         perfBucket == "3sec-7sec", 5,
         perfBucket == "7sec-15sec", 6,
         perfBucket == "15sec-30sec", 7,
         perfBucket == "30sec-1min" ,8,
         perfBucket == "1min-2min", 9,
         10)
| order by sortOrder asc
| project-away sortOrder

结果：

perfBucket	count_
250ms-500ms	14000
1sec-3sec	9700
7sec-15sec	600
