At scale you don't babysit miners one at a time — you watch the whole fleet from a monitoring tool. Foreman is a common one: it shows every miner's status, groups the failures by cause, maps them to physical locations, and can even act on them automatically.
A fleet-management tool polls every miner and rolls the results into one view: who's hashing, who's failing, what firmware and pools they're on, and how much power they pull. It turns thousands of machines into a dashboard you can triage from.
Most monitors reduce each miner to a simple state. In Foreman, the four that matter:
| Status | Means | What to do |
|---|---|---|
| Ok | Hashing at the expected rate for the model | Nothing |
| Warn | Hashing below the sticker rate | Investigate soon — a board or thermal issue is building |
| Fail | Under-hashing or not hashing at all | Triage now — expand it to see the reported issue |
| Disabled | Intentionally pulled / not to be pinged | Left off on purpose; not a fault |
