Hi, yesterday we had an outage in one of our S3 buckets and some resources failed to load on our websites (00.png). However, these errors were not visible in dynatrace (01.png). Is dynatrace only reporting errors with response headers 4xx/5xx? In this case, if it's clearly a failed state, shouldn't this also be visible in dynatrace?
I think in this case the request does not have a response code and probably also no java exception. This is per default not treated as an error as it might be a fire and forget call. You can however configure this in the error detection settings of a service.
