Field notes
Short notes from observability engagements — written for platform and engineering partners in Hong Kong and beyond.
Green boards can still be blind
When a service reports healthy while a critical span never fires, your observability is telling a comforting lie.
Name the span, not the screen
Pretty dashboards hide weak naming. Observability that lasts starts with span and attribute names humans can own.
Release day is a measurement day
Treat every deploy as a chance to prove observability still fires — not as a moment to hope last month’s signals survived.
