01 — Purpose

From telemetry to action

Observability workflows help teams detect and resolve frontend problems quickly — production issues should become visible rapidly.

Instrumentation alone is not enough. Teams need workflows: what gets alerted, who responds, how incidents tie to deploys, and when dashboards get reviewed. Without that, observability becomes noise.

See frontend observability and performance monitoring.

02 — Principles

Observability should support operational confidence

Error tracking, deployment correlation, dashboards, and incident review.

  • error tracking — client exceptions with route, release, and user context
  • deployment correlation — tag events with build ID; compare before/after
  • performance dashboards — CWV and key custom metrics with owners
  • incident review workflows — postmortems that update alerts and budgets

03 — Practice

Good observability workflows

Visible, actionable, reviewed — not a wall of graphs.

  • define SLOs and alert thresholds — error rate, LCP p75, failed API calls
  • on-call or triage rotation for frontend production alerts
  • weekly dashboard review — trends, not only firefighting
  • link errors to releases — rollback path when a deploy spikes JS errors
  • integrate with third-party governance — see third-party script governance when vendor tags change

04 — Avoid

Observability failure modes

Missing telemetry and alert fatigue both hide real problems.

  • missing telemetry — checkout or auth untracked
  • alert fatigue — pages of warnings nobody acts on
  • monitoring nobody reviews — dashboards with no weekly owner
  • no runbooks — on-call guesses instead of documented triage steps
  • PII in logs without redaction or consent process

05 — Close

Close the loop after incidents

Every production incident should improve the next alert or budget.

After an outage, ask: would our current alerts have caught it faster? Update thresholds, add missing spans, or fix noisy false positives.
