Server Room Temperature Monitoring Dashboard
Log temperature readings for a server room or IT closet and watch latest, average, min/max, in-range % and excursions against a °C acceptable band.
Acceptable band: 18–27 °C. Readings are timestamped and stored in your browser only.
Acceptable band 18–27 °C. Times use this device's clock (2026-06-08).
Field notes from maintenance practice
Measure at the server inlets (cold aisle, mid-rack height), not at the ceiling or the CRAC return — equipment lives or dies by the air it actually breathes, and inlet temperature is what every hardware warranty specifies. Most server-room heat problems are airflow problems, not cooling-capacity problems: a creeping average usually means blocked filters, a failed CRAC fan, or recirculation from missing blanking panels rather than an undersized chiller.
Consistency makes the numbers meaningful: measure at the same point, with the same instrument, at sensible intervals (continuous where the risk is high, spot-checks where it is low). The in-range percentage is the metric to watch — a band that quietly drifts from 100% toward 95% is telling you something is changing before any single reading alarms.

About Server Room Temperature Monitoring Dashboard
This dashboard turns scattered temperature checks for a server room or IT closet into a monitored series: log a reading whenever you measure and it tracks the latest value, the average, the min/max range, the percentage of readings inside the acceptable band and the number of excursions — the everyday telemetry picture, computed in your browser with no logger subscription. The default acceptable band is 18–27 °C, the ASHRAE recommended envelope for data-centre inlet air.
How to use Server Room Temperature Monitoring Dashboard
- 1Log a reading whenever you measure — each is timestamped and stored in your browser.
- 2The dashboard shows latest, average, min/max, in-range % and an excursion count against the acceptable band.
- 3Watch the sparkline and the in-range percentage — a falling in-range % is your early warning before a hard excursion.

Frequently asked questions
What is the acceptable temperature range for a server room or IT closet?+
The default band is 18–27 °C, the ASHRAE recommended envelope for data-centre inlet air. Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.
ASHRAE 'recommended' vs 'allowable' — which limit should I monitor against?+
Monitor against the recommended 18–27 °C band for routine operation; the wider allowable envelope (up to 32 °C+ for class A1) exists for short excursions and economiser operation, not as a daily target. Running continuously in the allowable-but-not-recommended zone trades a little energy saving for higher failure rates and shortened hardware life — fine briefly, unwise as a steady state.
How often should I log temperature readings?+
Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.
Is my logged data private?+
Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
