These are some good suggestions and things to look deeper into, but in the short term you may need to file a PMR with IBM to get the WebUI working: How to ask for IBM product help: PMRs, RFEs, and more
I have definitely thought of having a fixlet that would examine various logs to see if there are any issues and where as well as an analysis to report on the status of various of these parts which would make troubleshooting much easier.
One issue I run into is that relevance isn’t very good at examining log files efficiently. I generally want to know if there is an error message in a log file more recently than the last success message, or if there is a success message in the log more recently than the last of a particular error message.
