Welcome to your interview.
The question is on your right: Root Cause Metrics from Logs. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What metrics would you prioritize when analyzing server log data to identify the root cause of an unexpected system outage?
