The NA62 experiment at CERN targets the measurement of the ultra-rare $ {K}^{+}\to {\pi}^{+}\nu \overline{\nu} $ decay, and carries out a broad physics programme that includes probes for symmetry violations and searches for exotic particles. Data were collected in 2016–2018 using a multi-level trigger system, which is described highlighting performance studies based on 2018 data.
