Missing Jaeger icons in Linkerd UI

[hongbo-miao]

I saw in the version 2.10 doc
https://linkerd.io/2.10/tasks/distributed-tracing/

there should have Jaeger icons.

I can see all traces in Jaeger UI, but I do not see those Jaeger icons in Linkerd UI.

Any idea? Thanks

BTW, I saw in version 2.9 https://linkerd.io/2.9/tasks/distributed-tracing/

I need a config.yaml

tracing:
  enabled: true

Just want to confirm, I do not need it in 2.10, right?

Thanks for the feedback @hongbo-miao , that's a good find 👍
Indeed, that 2.9 config is not relevant for 2.10. For the 2.10 dashboard to show the jaeger links it requires that the web Deployment in the linkerd-viz namespace contains a flag pointing to the jaeger UI: jaeger-addr=jaeger.linkerd-jaeger:16686. That can be edited manually, or through the CLI (or equivalently through Helm) by upgrading the jaeger extension with linkerd jaeger install --set jaegerUrl=xxx. I'll open a ticket to clarify that in the docs.
OTOH, as a further improvement, this could be handled automatically by the dashboard component by dynamically figuring if the jaeger extension is installed...

Thanks @alpeb ! Just confirm, do you mean

linkerd viz install --set jaegerUrl=jaeger.linkerd-jaeger:16686

or

linkerd jaeger install --set jaegerUrl=jaeger.linkerd-jaeger:16686

?

Because we want to let Linkerd UI to point to Jaeger.

Oh, I guess it is just a typo.

Just confirmed the correct one is linkerd viz install --set jaegerUrl=jaeger.linkerd-jaeger:16686. Now I can see the Jaeger icons in Linkerd UI:
