As you see, the `randomSamplingPercentage` is 0, which means the tracing is still not enabled because of `0` sampling percentage. The tracing can be opt-on by increasing the `randomSamplingPercentage` value to `1-100`. The `Telemetry` resource can also be manipulated in workload/namespace/global levels, you can check [here](https://istio.io/latest/docs/reference/config/telemetry/) for more config examples.
