To cope with the telemetry limitations, the Polarimetric and Helioseismic Imager on Solar Orbiter does full on-board data processing. Metadata are central to the autonomous processing flow, crucial for providing science ready data sets to the community, as well as important in the blind debugging process that will occur in the commissioning phase. We designed a custom metadata logging system for SO/PHI. This paper shows how the logged information is used in the blind debugging scenario.
