Configuring Zipkin Tracing using GlobalConfig

EnRoute Technical Reference

EnRoute can be configured to generate Traces in Zipkin and OpenTelemetry format. Tracing can be configured using GlobalConfig

GlobalConfig for Zipkin Tracing #

Sending traces to zipkin collector is fairly straightforward. We specify the tracer_type as zipkin and provide the service name as <namespace.name>

Additional custom tags can also be sent to zipkin traces

Note that the example below assumes a zipkin collector is running in namespace istio-system with service name zipkin that accepts traces on port 9411

The GlobalConfig that enables tracing is defined of type globalconfig_tracing
