Otherwise the traces may not be reported.

## Update mesh config

Install or update Istio with the `demo` profile to make sure you have the OpenTelemetry tracing provider enabled:

```bash
istioctl install --set profile=demo -y
```

Or ensure you have the following additional mesh config set in your Istio:

```yaml
mesh: |-
  extensionProviders:
  - name: otel-tracing
    opentelemetry:

      This default setting has been removed; users will need to explicitly configure where to send traces moving forward.

      `istioctl x precheck --from-version=1.21` can automatically detect if you may be impacted by this change.

      If you previously had tracing enabled implicitly, you can enable it by doing one of:

/common-protos/                                                  @istio/wg-test-and-release-maintainers
/install/                                                        @istio/wg-environments-maintainers
/istioctl/                                                       @istio/wg-user-experience-maintainers @istio/wg-networking-maintainers

- [istio/istio](README.md). This is the main code repository. It hosts Istio's
core components, install artifacts, and sample programs. It includes:

    - [istioctl](istioctl/). This directory contains code for the
[_istioctl_](https://istio.io/latest/docs/reference/commands/istioctl/) command line utility.

    - [operator](operator/). This directory contains code for the
[Istio Operator](https://istio.io/latest/docs/setup/install/operator/).

inputs in the analyzer metadata. This should help you find any unused inputs and/or missing test cases.

### 6. Testing via istioctl

You can use `istioctl analyze` to run all analyzers, including your new one. e.g.

```sh
make istioctl && $GOPATH/out/linux_amd64/release/istioctl analyze
```

### 7. Write a user-facing documentation page
