The only thing were this made me disagree is the notion that system administrators aren't fully aware of those issues. We are just in a situation where we get delivered with software that is usually unmaintainable written by people who most do not care. Either you got no logs, broken logs, logs that DO NOT LOG IF SOMETHING GOES WRONG or log4j logs that nothing more than a application trace and usually has 10%+ of messages that are wrongly classified, or, the thing i love most, people who think that a python backtrace is error handling. This is why we insist on seeing a system built in the isolated lab, so that we can build filters that represent the "normal application behaviour" and can immediately recognize when it goes to hell. Adding more and more log datapoints is and splunking the data is a nice help, but not enough; and that's where i'm back to agreeing: we all need to get better in building systems that are planned on the notion that failure can happen.
