Question about Istio Standard Metrics missing in application pod

[Jackson-Stard]

Bug Description

I am new hand for Istio, and I found that I cannot get Istio Standard Metrics in my own application pod, but it works well if I deploy bookinfo in my cluster.
I spent more time to figure it out, but failed, I think it should be something wrong with my application pod, maybe missing some configuration, could anyone happen to know how to fix it?

my test application is webtest, it is quite simple just one api call, istio injection is enabled.

I can see the istio_requests_total metric from istio ingress gateway through localhost:15000/stats/prometheus, same as bookinfo, but I cannot see it in my webtest pod.

The log for istio-proxy in my webtest pod is like below: the request id is null, and it is quite different with bookinfo

Thanks for you help!

I attached the config_dump file, thanks.

[Jackson-Stard]

can you share the config_dump of the webtest pod?

I checked the config_dump, I did not find inbound router for webtest.promtest.svc.cluster.local:80/, but I find inbound route for productpage.bookinfo.svc.cluster.local:9080/.

I am wondering why there is no inbound route for webtest.

do you follow this?

do you follow this?

My service definition like this, oh, I should use http, right?

apiVersion: v1
kind: Service
metadata:
namespace: promtest
name: webtest
spec:
selector:
app: webtest
ports:
- protocol: TCP
port: 9876
name: tcp-webtest
targetPort: 80

[Jackson-Stard]

it looks it works if I change it to http
