Jaeger

    This task uses the Bookinfo sample as the example application.

    To learn how Istio handles tracing, visit this task’s .

    1. Follow the documentation to deploy Jaeger into your cluster.

    2. When you enable tracing, you can set the sampling rate that Istio uses for tracing. Use the option during installation to set the sampling rate. The default sampling rate is 1%.

    3. Deploy the sample application.

    For testing (and temporary access), you may also use port-forwarding. Use the following, assuming you’ve deployed Jaeger to the istio-system namespace:

    1. From the left-hand pane of the dashboard, select productpage.default from the Service drop-down list and click Find Traces:

    2. Click on the most recent trace at the top to see the details corresponding to the latest request to the /productpage:

    3. The trace is comprised of a set of spans, where each span corresponds to a Bookinfo service, invoked during the execution of a request, or internal Istio component, for example: istio-ingressgateway.
