In this work, we conduct a comprehensive survey study on log analysis at Microsoft. We collected feedback from 105 employees through a questionnaire of 13 questions and individual interviews with 12 employees. We summarize the format, scenario, method, tool, and pain points of log analysis. Additionally, by comparing the industrial practices with academic research, we discuss the gaps between academia and industry, and future opportunities on log analysis with four inspiring findings. Particularly, we observe a huge gap exists between log anomaly detection …
