I’ve found that Live Logging is more reliable (i.e. more of the messages displayed more of the time) when I’m using a wired ethernet connection to my router, compared with a wireless-n connection on my laptop. Though it’s still not 100%.
I agree that this lack of completeness and consistency in the Live Logging output is highly undesirable considering it’s intended purpose for debugging. It is no doubt causing a lot of confusion and unnecessary headaches for community developers.
Not sure if the issue has been covered in this thread: Tell me your IDE issues
FYI, to combat the problem, I implemented a form log concatenation/pagination in my Z-Wave Tweaker DTH.
