I saw that. But I think, a lot of logging data contains personal data of users.
I’m not asking, if you are going to strip out data like file paths, etc.
For example, I use sentry for a django site and set it up according to the instructions on https://docs.sentry.io/clients/python/integrations/django/. This way, if an error occurs, it is logged at sentry with the user email. I believe a lot of your customers are in the same situation.
If they do business in europe, they have to be compliant with the GDPR. That means, they have to sign a data processing contract with you or they have to make sure, that no personal data is logged.
