Vight field notes
Engineering decisions, practical investigation guides, and the boundaries we publish before they become incidents.
APM principles
A chart is a clue, not a conclusion.

Dashboards are good at showing that production changed. An APM workflow earns its keep by preserving scope while it takes you from a bad percentile to the request that explains it.
Principles · 6 min readSEPTEMBER 04, 2026
The most useful production logs capture a decision, its inputs, and its outcome. Everything else competes for attention and retention when an incident is already moving fast.
EngineeringSEPTEMBER 04, 2026
More spans do not automatically produce better traces. Instrument the boundaries where latency, ownership, or failure semantics change—and make each span earn its place.

Alert fatigue is an accounting problem. Make every page name the impact, owner, first action, and recovery condition before it can draw from the team’s attention budget.

A useful SLO changes release, staffing, or reliability work before the error budget is gone. Start with the decision, then choose the indicator and objective.

Self-instrumentation, unbounded joins, and small inserts can turn an observability pipeline into its own largest workload. Here’s how to fix that without losing customer evidence.
