Tracing in Istio environments should be seamless, but too often, teams run into a frustrating problem—traces are broken. Requests jump between services, but instead of a complete flow, Coralogix displays fragmented spans. Tracing should work out of the box in those environments. Istio’s sidecars capture spans automatically, so why are traces incomplete? The issue is almost always context propagation, and fixing it doesn’t have to mean modifying application code.
