KQL - Aggregate on latest entry

问题

期望输出：

标题 TimeGenerated IncidentNumber 严重性 状态 事件URL
Microsoft Defender Threat Intelligence Analytics 2023年8月2日，上午7:38:01.313 94945 高 新 链接

因为事件 94944 的最新条目状态为 '已关闭'，所以它会被排除。

英文:

I am trying to aggregate open high incidents from Azure Sentinel. Since incidents are updated in logs every time a change is made, this means that there is a latest iteration of an incident being Status 'New' and a latest entry for Status 'Closed'. Since I cannot just filter out | where Status != "Closed", since that would leave the latest entry for when it was 'new', what would the aggregation query here be?

What I got:

SecurityIncident
| where Severity == "High"
| summarize arg_max(TimeGenerated, *) by IncidentNumber,Title,Severity, Status, IncidentUrl
| where IncidentNumber == "94944"
| project Title, TimeGenerated,IncidentNumber,Severity, Status, IncidentUrl
| order by TimeGenerated desc

Data Set

Title,"TimeGenerated [Local Time]",IncidentNumber,Severity,Status,IncidentUrl

Expected Output:

As the incident 94944 would be dropped since its latest entry was status 'closed'

得分: 1

如果我正确理解你的问题：

  1. 你提供的输出与任何输入记录都不匹配 - 因此我怀疑你输错了
  2. 你想要使用arg_max()聚合函数进行聚合，以获取每个事件ID的最新记录。
    然后，你想要筛选出状态不是"Closed"的记录。

即：

datatable
(
    Title: string,
    ['TimeGenerated [Local Time]']: datetime,
    IncidentNumber: long,
    Severity: string,
    Status: string,
    IncidentUrl: string
)

英文:

If I understood your question correctly:

  1. the output you've provided doesn't match any of the input records - thus I suspect you mistyped it
  2. you want to aggregate using the arg_max() aggregation function to get the latest records for each incident ID.
    then, you want to filter only for those records whose status isn't "Closed".

i.e.:

datatable
(
    Title: string,
    ['TimeGenerated [Local Time]']: datetime,
    IncidentNumber: long,
    Severity: string,
    Status: string,
