Public bug reported:

In a kubernetes model, we have some kubernetes-worker charms
(kubernetes-worker-gpu) with a relation to an nrpe charm (nrpe-
kubernetes-worker-gpu). The nrpe charm has a relation to a nagios charm
(nagios-server-k8s).

If we list the nrpe-checks it looks like we have a few:

$ juju run-action --wait nrpe-kubernetes-worker-gpu/2 list-nrpe-checks
unit-nrpe-kubernetes-worker-gpu-2:
  id: a806dd9c-dd05-49af-8635-aef467123586
  results:
    checks:
      check-arp-cache: /usr/local/lib/nagios/plugins/check_arp_cache.py -w 60 -c 80
      check-conntrack: /usr/local/lib/nagios/plugins/check_conntrack.sh -w 80 -c 90
      check-disk-root: '/usr/lib/nagios/plugins/check_disk -u GB -w 25% -c 20% -K
        5% -p / '

But we don't find all of them in nagios:
