Path Tracing for Mesh Fatigue
When every hop has a sidecar, understanding a single request becomes the audit.
Service meshes promise uniform policy and then bury failure modes under layers of proxies. Path tracing restores clarity: pick a critical user journey, enumerate every hop, and ask what happens when that hop is slow, unavailable, or misconfigured.
We regularly find retries that amplify load, mTLS settings that disagree across namespaces, and gateway filters that rewrite headers in ways application teams never see. Fixing one of those often removes more pain than adding another dashboard.
Keep the trace artifact short. One diagram, one table of failure modes, one prioritized change list. That is enough to steer the next sprint.
