not really a serious concern, but what happens when ticket automation goes down? If all the problems are auto-reported, in a form of tickets or tasks, then if that somehow breaks down it might take a moment before anyone notices, especially if reported exceptions are rather rare. If it is normal to have tens of tickets every day, then problems with ticket creation will be noticeable almost instantly, if they are very rare - then not so much
The second issue with automated exception tracking is that you loose the "huh, this is weird" mechanism that works when actual humans go through logs or reports. While any tool will of course be orders of magnitude faster and also probably more accurate, by relying solely on such automation an opportunity to notice some "weird"/not-typical entries or rare/unexpected sequences of those might be missed. Then again in most cases - I guess - simple statistical analysis might be a good substitute. And that can be automated. (edit: formatting)
