Hello @piotrblasiak, can you please elaborate on why you'd like to disable the filter? Is it filtering too much? There'll likely be a lot more events being sent to Sentry, consuming your quota.

I'm actually surprised the filter is enabled by default - I want to be able to see how often some errors occur. Some one-time errors may not be super serious, but some may affect a lot of users and should be dealt with as soon as possible. Is this not a very common way to reason about error reporting?

[adinauer]

Hmm maybe there's a misunderstanding here, the filter shouldn't filter out a similar error happening again but instead is meant to filter out actual duplicates, e.g. when a logging integration as well as an exception handler try to capture the same exception twice.

[piotrblasiak]

Well, if the exact same exception happens for different users, I want to know about that - also even if it's for the same user but at different times it is valuable to know, no? Why else would your dashboard show how many times an error has happened?

[adinauer]

It'd have to be the exact same Throwable reference (i.e. ==) being captured again for it to be filtered out by DuplicateEventDetectionEventProcessor, so in the case you're describing it should NOT filter it out. Did you run into problems when playing around or is this a theoretical concern?

Aha ok, I thought I had read it compared the stack traces and not the object references. If that's the case, I guess all is fine. Thanks.
