is there any guide/tutorial on how to troubleshoot workflow errors and match them to sharepoint ULS logs?

especially ones that are intermittent (not reproducible), very general and that do not provide correlation ID (like workflow failed, workflow failed to start, etc) ...

I see basically no reliable entity I can pick from workflow resp. error message to base search of ULS on - as mentioned there is no correlation ID, workflow history log entries timestamps are on minute level which too rough for ULS logs, searching by error message (sub)string very rarely leads to a result.

I've read some discussions on the forum, but haven't found satisfactory answer.

could you share your experience/approach?
