MS Analysis periodically rebuilds indexes. How to track / control?

Question

OLAP

Periodically, when recalculating an analytics cube, Microsoft Analysis Service rebuilds the indexes, which shifts the cube calculation time by an hour or two compared to the usual preparation time.
Is it possible to somehow track the prerequisites for the recalculation of indices, or track the very fact of launching such a recalculation? Keeping the trace permanently in SQL Profiler is not suitable.
