<p>Enables requests served by NGINX for distributed tracing via The OpenTracing Project.</p>
<p>Using the third party module <a href="https://github.com/opentracing-contrib/nginx-opentracing">opentracing-contrib/nginx-opentracing</a> the NGINX ingress controller can configure NGINX to enable <a href="http://opentracing.io">OpenTracing</a> instrumentation.
By default this feature is disabled.</p>

<p>All these options (including host) allow environment variables, such as <code class="codehilite">$HOSTNAME</code> or <code class="codehilite">$HOST_IP</code>. In the case of Jaeger, if you have a Jaeger agent running on each machine in your cluster, you can use something like <code class="codehilite">$HOST_IP</code> (which can be 'mounted' with the <code class="codehilite">status.hostIP</code> fieldpath, as described <a href="https://kubernetes.io/docs/tasks/inject-data-application/downward-api-volume-expose-pod-information/#capabilities-of-the-downward-api">here</a>) to make sure traces will be sent to the local agent.</p>
