In azure how to concatenate strings in a summarize statement?

Question

I have a statement where I try to concatenate logs (strings) together to a single string.

Something like this

ContainerLog
| where conditions
| summarize strcat(LogEntry) 

However I cant figure out how to concatenate strings like this since strcat is not an aggregating function. I need something else but don't know what.

How can I do this?

For example if I have log entries "1","2","3" the final result should be "123"

Answer 1

This allows a distinct combination in concrete.

requests
| where URL contains "prod"
| summarize count(), code=make_set(resultCode) by name
| sort by count_ desc
