Please, say what info i should give?
we are using Loki as a Data Sourse, panel – Time Series
my query something like that:

sum by (url)
(count_over_time(
{'labels'}
|~ "\"response_code\":\"5.*\"" 
| json 
[$__interval]))

In screenshot above I try to show that i have a few strings with different urls which show how much 5xx errors we have on that url.
I want to merge all strings which starts from /imgprx/.* and summarize their values

Hi, have the same problem. Same errors are summed, but clientid is also part of the label message, so they are seperated. I want all of them summarized into one. ClientId is unimportant

Query:
sum by(message) (count_over_time({customer=“123”,product=“456”} | json | level=“ERROR” [1s]))

Why i do this?:
I want to display the most common errors

Not shure if there is more info needed. Please reach out to me
