  We tackle the challenging tasks of monitoring on unstable HPC platforms the
performance of CFD applications all along their development. We have designed
and implemented a monitoring framework, integrated at the end of a CI-CD
pipeline. Measures retrieved during the automatic execution of production
simulations are analyzed within a visual analytics interface we developed,
providing advanced visualizations and interaction. We have validated this
approach by monitoring the CFD code Alya over two years, detecting and
resolving issues related to the platform, and highlighting performance
improvement.
