task shows you how to configure Istio to collect trace spans and send them to <a href=https://lightstep.com/products/>LightStep Tracing</a> or <a href=https://lightstep.com/products/>LightStep [𝑥]PM</a>.
|
||
LightStep lets you analyze 100% of unsampled transaction data from large-scale production software to produce meaningful
|
||
distributed traces and metrics that help explain performance behaviors and accelerate root cause analysis.
|
||
At the end of this task, Istio sends trace spans from the proxies to a LightStep Satellite pool making them
|
||
available to the web UI.</p><p>This task uses the <a href=/v1.3/docs/examples/bookinfo/>Bookinfo</a> sample application as an example.</p><h2 id=before-you-begin>Before you begin</h2><ol><li><p>Ensure you have a LightStep account. <a href=https://lightstep.com/products/tracing/>Sign up</a> for a free trial of LightStep Tracing, or <a href=https://lightstep.com/contact/>Contact LightStep</a> to create an enterprise-level LightStep [𝑥]PM account.</p></li><li><p>For [𝑥]PM users, ensure you have a satellite pool configured with TLS certs and a secure GRPC port exposed. See
|
||
<a href=https://docs.lightstep.com/docs/satellite-setup>LightStep Satellite Setup</a> for details about setting up satellites.</p><p>For LightStep Tracing users, your satellites are already configured.</p></li><li><p>Ensure sure you have a LightStep <a href=https://docs.lightstep.com/docs/project-access-tokens>access token</a>.</p></li><li><p>You’ll need to deploy Istio with your satellite address.
|
||
For [𝑥]PM users, ensure you can reach the satellite pool at an address in the format <code><Host>:<Port></code>, for example <code>lightstep-satellite.lightstep:9292</code>.</p><p>For LightStep Tracing users, use the address <code>collector-grpc.lightstep.com:443</code>.</p></li><li><p>Deploy Istio with the following configuration parameters specified:</p><ul><li><code>pilot.traceSampling=100</code></li><li><code>global.proxy.tracer="lightstep"</code></li><li><code>global.tracer.lightstep.address="<satellite-address>"</code></li><li><code>global.tracer.lightstep.accessToken="<access-token>"</code></li><li><code>global.tracer.lightstep.secure=true</code></li><li><code>global.tracer.lightstep.cacertPath="/etc/lightstep/cacert.pem"</code></li></ul><p>If you are installing via <code>helm template</code> you can set these parameters using the <code>--set key=value</code> syntax
|

when you run the <code>helm</code> command. For example:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ helm template \

<code>productpage.default: proxy client</code> service. This service represents the client-side span of the call. The screenshot shows

To learn how to modify the trace sampling percentage,

visit the <a href=../overview/#trace-sampling>Distributed Tracing trace sampling section</a>.

When using LightStep, we do not recommend reducing the trace sampling percentage below 100%. To handle a high traffic mesh,

consider scaling up the size of your satellite pool.</p><h2 id=cleanup>Cleanup</h2><p>If you are not planning any follow-up tasks, remove the Bookinfo sample application and any LightStep secrets
