comment FreeNAS/FreeBSD: How to access status of ZFS volume from jail?
FreeNAS has a read-only root filesystem that it typically boots off USB flash drive, so installing NRPE to it appears to be a fool's errand (although this fool has sure tried). That means your main option for running anything beyond the base install is a Jail. You are of course right that the jail is meant for this kind of security restriction, but it's also one of my only options for running additional software that isn't included in the base FreeNAS platform.

That's a good suggestion. I've done things like this before. But I do find that I have to add an extra level of complexity to the checking, to make sure that the results of the job aren't stale (cron script is still running, permissions haven't changed, etc. etc.) It also makes checks less immediate, which can be confusing and aggravating when you are trying to see status in a crisis. But this is a workable solution, so thank you for it.
