Zfsget not showing accurate pool data

I’m a junior admin trying to use check_mk analytics to track increased storage growth for research in an HPC environment after COVID-19. One of the things I’m running into is that a Filesystem check for our ZFS pools on each storage server (roughly 15 of them) are not showing accurate information, but it does on other hosts.

Could I get assistance in troubleshooting this issue? I’ve attached a screenshot – the relevant field is “Filesystem /dpool01”
