I don't think so. I don't want to trigger a Problem for each 404 request. I know that I can trigger problems and I will based on a certain amount of 404 during a certain time range. But this is not my question.
You can create a custom chart for "4XX" Errors with details.
For API, you can extract the same using timeseries API "com.dynatrace.builtin:service.errorcounthttp4xx"
If I wasn't to count all errors with timeseries API: "com.dynatrace.builtin:service.errorcounthttp4xx", I want the possibility to extract/export all 4xx and 5xx errors with detailed exceptions text and then elaborate a personalized report with the detailed exception text who more appear in the last two hours by example.
can I export all this from dynatrace API?
