What can we conclude from this?
First, a "duh" conclusion is in order! No matter how many times one can utter the word "compliance," logs are still most useful for mundane (one would hope! :-)) system administration. Yes, indeed, sysadmins are the primary consumers of logs - yesterday, today, and - likely! - tomorrow as well.
Second, I am saddened by the fact that application developers have not warmed up to logs, at least no en masse (and not according to this limited poll...). I am guessing when they start thinking of logging when creating their applications, they will be more aware of the fact that you can troubleshoot the applications using logs ...
Third, incident response team showing that low is some kind of fluke, I am sure. Everybody knows that logs are indispensable during incident response (yes, even if only a little logging was enabled or even logging defaults left in place, logs often reveal answers unobtainable via any other mechanisms)
Am I reading too much into this? Hey, maybe I am! :-) Then again, I am a former theoretical physicist - thus, I can explain anything!
Next poll coming soon!
