The document summarizes a predictive monitoring solution implemented by Capgemini for the French Civil Aviation Authority (DGAC). The solution uses an open-source IT operations analytics (ITOA) framework called Thunderstruck that incorporates predefined artificial intelligence algorithms. It allows DGAC to identify and resolve issues before they impact critical applications used by 500 users. This is expected to reduce the number of annual crises by 40% and lower crisis duration and number of people involved through more proactive, application-focused monitoring versus traditional reactive supervision. Lessons learned include starting small and incrementally, thoroughly understanding data and applications, and treating AI as a boost rather than the primary solution.
