A monitoring point needs a clock
The minimum a data center monitoring point must have before it is allowed to wake someone.

Independent engineering checklists, mathematical balance equations, and refusal criteria derived from this field volume.
The minimum a data center monitoring point must have before it is allowed to wake someone.
What a data center health score may sort, and the decisions it must not be given a pen for.
How to hold a data center alarm storm as one event without inventing a root cause from the clock.
Live, stale, and missing are the only quality marks a data center screen should be obeyed for.
Forced failure, clock, opened alarm row, stale score, maintenance window, and a page a person can read. Not a product ranking.
A data center maintenance window may stop pages. It may not delete the record or hide a different failure.
A detector that draws a band around history has not found an incident. The band width is a choice. Do not erase the points first.
Optimizer output is a hypothesis. Only a live power point, against a baseline written first, may support a saving.
Hours when tower or pump power is zero are shutdown, not an efficient setpoint. Take them out before the fit.
Weather, flow, and water temperatures are conditions. Tower count and fan speed are the only things a search may move.
A cooling-tower fit that does not cool more at a higher fan speed is the wrong fit. Do not search it.
If the towers only ran one way, a fit has no evidence for the speeds a search will propose.
A fitted model may suggest fan speed and how many towers to run. It may not command them, or claim a saving it did not measure.
A model that treats every cell as the same machine will hide a weak tower and then recommend it.
