Quality improvement of practical cybersecurity training is challenging due to the process-oriented nature of this learning domain. Event logs provide only a sparse preview of trainees' behavior in a form that is difficult to analyze. Process mining has great potential in converting events into behavioral graphs that could provide better cognitive features for understanding users' behavior than the raw data. However, practical usability for learning analytics is affected by many aspects. This paper aims to provide an experience report summarizing key features and obstacles in integrating process discovery into cyber ranges. We describe our lessons learned from applying process mining techniques to data captured in a cyber range, which we have been developing and operating for almost ten years. We discuss lessons learned from the whole workflow that covers data preprocessing, data mapping, and the utilization of process models for the post-training analysis of Capture the Flag games. Tactics addressing scalability are explicitly discussed because scalability has proven to be a challenging task. Interactive data mapping and Capture the Flag specific features are used to address this issue.
