The log of web-svc

[khalid-huang]

When I reproduce the bare version (no istio or linkerd), the log of web-svc is a little strange for me

The similar situation happend in the istio version,

Is this expected?

Does the wrk2 pod report any HTTP error codes or socket errors after the run?

[khalid-huang]

There is no any HTTP error codes or socket errors after the run. I think this is expected. But I still edit the wrk2.yaml.tmpl to avoid using api/list

        - "http://web-svc-1.emojivoto.svc.cluster.local:8080"
        - "web-svc-1"
        - "${INSTANCES}"
        # - "api/list
        - "api/vote?choice=:flushed:"
        - "api/vote?choice=:policeman:"
        - "api/leaderboard"
