What to Measure When You Migrate to Edge Routing

The short answer: Measure route latency, auth failures, upstream error rates, config change safety, and incident recovery time so the migration is judged on outcomes instead of slogans.

When to read this

• You are planning or validating a move to an edge gateway.
• You need a small observability checklist for stakeholders.
• You want proof that the migration improved the client-facing API experience.

What matters in practice

• Latency alone is not enough.
• Operational simplicity and error reduction are meaningful migration outcomes too.
• Choose a small set of metrics that map to user experience and support load.

Concrete example

    - Per-route latency
  - Auth failure rate
  - Upstream 5xx rate
  - Config-change rollback time
  - Support incidents caused by route or auth drift

The example above is intentionally small because the best gateway configs stay readable. Add only the route, auth, and mapping behavior you actually need.

How this maps to the current gateway

The current codebase already supports the behavior discussed here through its config schema, route matcher, and integration handlers. That is why this project is a good fit for reader-first examples: the docs and blog can point to real, implemented behavior instead of hypothetical gateway features.

What this product does not do

• The repo does not include a built-in metrics dashboard.
• You will need external observability tooling for full operational visibility.

FAQ

What is the easiest metric to start with?

Per-route latency and auth error rate.

What metric gets overlooked most often?

Change safety, especially whether config edits are easier to review and roll out than before.
