nfsstat and sysstat are OnTap commands used for performance information.
sio_ntap_soll is not an OnTap command.
Perfstat is a GUI performance tool, not an OnTap command. Think of PerfMon for Windows to remind you that
PerfStat is a Windows tool. Note how many of the ONTAP performance commands end in stat.
