Missed that statement. I take “fixated” back the rest you can keep, ;-).

Hi William L.,

“fixated” seems a bit strong a word when I explicitly wrote that “configuration-based models are a complement to runtime transaction discovery, not a replacement”.

I am curious why you seem fixated on the actual static configuration rather than the actual dynamic behavior patterns and runtime state.

What has [config] changed? Should that not be what new behavioral & state patterns have we detected in our system. A configuration change does not necessarily imply a change in actual software or system execution behavior though I will admit that it is a good starting point when you have nothing else to go on.

Maybe it a difference in perspective. I seek to understand (largely observation based) and acquire knowledge whereas most are just looking to take corrective action (incident mode) which typically means roll back but without the search for the underlying “why X” and no knowledge acquisition.

Coming from a programming background I see both the dynamic system and software execution models as the ultimate configuration management databases. But then again I love the hard challenges.
