将KQL数组拆分为多个列

Question

我试图在Azure哨兵的工作簿中构建一个仪表板。其中一列是可变长度的JSON数组。我想拆分这个数组让数组中的每个元素都有自己的一列，但我想不出一个好办法。我想要这个

-----------------------------------
Company | products
-----------------------------------
Apple     | [iMac, iPhone, iPad]
Microsoft | [xBox, xBox 360]
Google    | [Chromebook]
--------------------------------------

成为

-----------------------------------
Company | product_1 | product_2 | product_3
-----------------------------------
Apple | iMac        |iPhone     |iPad
Microsoft | xBox    |xBox 360   |
Google | Chromebook |           |
--------------------------------------

Answer 1

效率不高，但这里有一个选项:

datatable(company:string, products:dynamic)
[
"Apple",     dynamic(['iMac', 'iPhone', 'iPad']),
"Microsoft", dynamic(['xBox', 'xBox 360']),
"Google",    dynamic(['Chromebook']),
]
| mv-apply with_itemindex=i products on (
extend p = pack(strcat("product_", i+1), products)
| summarize b = make_bag(p)
)
| evaluate bag_unpack(b)
| project-reorder company, product* asc

——比;

| company   | product_1  | product_2 | product_3 |
|-----------|------------|-----------|-----------|
| Apple     | iMac       | iPhone    | iPad      |
| Microsoft | xBox       | xBox 360  |           |
| Google    | Chromebook |           |           |
