OpenCensusAgent trace provider (W3C Trace Standard) is not working in Istio
My application code follows W3C Trace Context Standard for distributed tracing. But by default, Istio follows a different standard. I need to make istio to follow W3C Trace Standard. After some research I found istio supports OpenCensus trace provider which follows W3C Trace Standard. When I add
How to use OpenCensusAgent in istio? to follow W3C Trace Context Standard
I have installed the below configuration (on top of demo profile) but still doesn't recognize traceparent header that is passed in the request.
# openCensus.yaml
apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
spec:
values:
global:
proxy:
tracer: openCensusAgent
Install using below command
istioctl install -f openCensus.yaml
When I check in jagger, it shows it's still using zipkin
Here is the whole configuration of istio
