The 3 AM Dashboard: Built for Tired Eyes

What an on-call sees at 3 AM should be different from what they see at 3 PM. Design rules for tired-eye dashboards.

Contrast wins

High contrast colors. Tired eyes lose subtle differences.

Red is alarm; green is OK; orange is warn. No clever color schemes.

Lower density

Fewer panels, larger text. Tired eyes do not parse 20-panel grids.

8-10 panels is the upper limit for the 3 AM dashboard.

Triage flow

First panel: 'is anything broken?' Big text, red or green.

Second panel: 'what is broken?' Top 5 worst services. Click-through to detail.

The on-call should not need to think about what to look at first.
