Question/Feature Request: Filter out status codes #28

Closed RangarajKaushikSundar closed 5 years ago

Is there a way I can completely filter out certain status codes? The formatStatusCode function gives us the option to combine status codes, but not ignore them.

disjunction commented 5 years ago

There is no way, and I agree it would be nice to have it.

As a workaround you can transform the status_code to say "ignored". And then delete or change the other labels so that all those are collapsed into just one line in metrics. It shouldn't have any impact on the traffic or performance this way.

Good idea. You can close this issue OR keep it open as a feature request. 😄

BTW. Thanks for the quick response @disjunction 👍

@disjunction Could you share an example for this?
