Narrative:
Cleared to descend via STAR. Set bottom altitude; then selected VNAV. Vta (vertical track alert) captured and first window of FL240. I noticed that altitude constraint was not captured passing through FL236. We selected alt and reported to ATC. Set automation but continued to monitor through all phases of flight.
