We use Qlik Web Connectors quite extensively to extract data from different web services. In case of reload failures we need to investigate QWC logs to find out root cause. I've tried and failed to load those xml logs into Qlik Sense to create a simple log monitor, because the xml can have different structure based on whether or not it contains an error and what kind of error it is. We need those logs in a different format to be able to monitor them in a user friendly way.
(Or a better support for xml in QSE, but I guess that's not an option.)
