在 Application Insights 分析中,如何查询受特定异常影响的用户百分比?
In Application Insights analytics how to query what percent of users are impacted by specific exception?
我使用这个查询来显示异常:
exceptions
| where application_Version == "xyz"
| summarize count_=count(itemCount), impactedUsers=dcount(user_Id) by problemId, type, method, outerMessage, innermostMessage
| order by impactedUsers
如何查询受特定异常影响的用户百分比?
我将通过此查询检查所有用户:
customEvents
| where application_Version == "xyz"
| summarize dcount(user_Id)
你几乎已经有了你所拥有的,你只需要将两者联系起来:
- 使用
let
+ toscalar
将查询结果定义为数字
- 在你的查询中引用它(我使用
*1.0
强制它是一个浮点数,否则你得到 0,并使用 round
得到 2 位小数,根据需要调整它)
进行查询:
let totalUsers = toscalar(customEvents
| where application_Version == "xyz"
| summarize dcount(user_Id));
exceptions
| where application_Version == "xyz"
| summarize count_=count(itemCount),
impactedUsers=dcount(user_Id),
percent=round(dcount(user_Id)*1.0/totalUsers*100.0,2)
by problemId, type, method, outerMessage, innermostMessage
| order by impactedUsers
