Describe the problem you'd like to have solved

It would be great if we could see the reason as a label in these series. I realize it could dramatically increase cardinality but it would be nice to at least have the option to include it.

Describe the ideal solution

There is a flag that enables the reason field being collected from the log and added to the failed series.

I'll give this a look, having it as a flag option might be the simpler way to avoid disrupting others.
Do you mind describing how this feature might improve usability?

[hobbsh]

Thanks! As for improving usability, it would just allow people to filter events by specific failures and also uncover the underlying reason for failures. I am not sure how many reasons Auth0 has, but it's probably not just a handful, so it could have a negative impact in other ways than just high cardinality. It would be good to know how feasible this is though.

It seems feasible looking a the Auth0 API, each log item seems to have a description, https://auth0.com/docs/deploy-monitor/logs/log-event-type-codes.
Is this the info you were hoping to have under a reason label?
