So now that this is a thing do I need to set up a cron job for every drive so that scrutiny can see the drive health?

Good news: you do not need a cron job per drive.

TrueNAS 25.10 removed the SMART scheduling UI but kept smartmontools installed, so Scrutiny's collector works fine.

How to set it up:

The Scrutiny collector auto-detects all drives on the system. Run one collector instance and it covers everything.

Option 1 — Built-in scheduler (persistent process):

scrutiny-collector-metrics run --cron-schedule "0 * * * *"

The collector loops internally — no system cron needed.

Option 2 — Docker Compose with env var:

environment:
  - COLLECTOR_CRON_SCHEDULE=0 * * * *

Option 3 — Single run via system cron (one entry total):

0 * * * * scrutiny-collector-metrics run

One entry, all drives covered. TrueNAS's new 90-minute background polling handles basic health; Scrutiny gives you full history, thresholds, and notifications on top of that.
