Mac</h2><p>Istio is installed and everything seems to be working except there are no traces showing up in Zipkin when there
should be.</p><p>This may be caused by a known <a href=https://github.com/docker/for-mac/issues/1260>Docker issue</a> where the time inside
containers may skew significantly from the time on the host machine. If this is the case,
when you select a very long date range in Zipkin you will see the traces appearing as much as several days too early.</p><p>You can also confirm this problem by comparing the date inside a Docker container to outside:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ docker run --entrypoint date gcr.io/istio-testing/ubuntu-16-04-slave:latest
Sun Jun 11 11:44:18 UTC 2017
</code></pre><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ date -u
Thu Jun 15 02:25:42 UTC 2017
</code></pre><p>To fix the problem, you&rsquo;ll need to shutdown and then restart Docker before reinstalling Istio.</p><h2 id=missing-grafana-output>Missing Grafana output</h2><p>If you&rsquo;re unable to get Grafana output when connecting from a local web client to Istio remotely hosted, you
should validate the client and server date and time match.</p><p>The time of the web client (e.g. Chrome) affects the output from Grafana. A simple solution
to this problem is to verify a time synchronization service is running correctly within the
Kubernetes cluster and the web client machine also is correctly using a time synchronization
service. Some common time synchronization systems are NTP and Chrony. This is especially
problematic in engineering labs with firewalls. In these scenarios, NTP may not be configured
properly to point at the lab-based NTP services.</p><h2 id=mixer-telemetry-issues>Mixer Telemetry Issues</h2><div><aside class="callout warning"><div class=type><svg class="large-icon"><use xlink:href="/v1.5/img/icons.svg#callout-warning"/></svg></div><div class=content>Mixer is deprecated. The functionality provided by Mixer is being moved into the Envoy proxies.
Use of Mixer with Istio will only be supported through the 1.7 release of Istio.</div></aside></div><h3 id=expected-metrics-are-not-being-collected>Expected metrics are not being collected</h3><p>The following procedure helps you diagnose problems where metrics
you are expecting to see reported are not being collected.</p><p>The expected flow for metrics is:</p><ol><li><p>Envoy reports attributes from requests asynchronously to Mixer in a batch.</p></li><li><p>Mixer translates the attributes into instances based on the operator-provided configuration.</p></li><li><p>Mixer hands the instances to Mixer adapters for processing and backend storage.</p></li><li><p>The backend storage systems record the metrics data.</p></li></ol><p>The Mixer default installations include a Prometheus adapter and the configuration to generate a <a href=/v1.5/docs/reference/config/policy-and-telemetry/metrics/>default set of metric values</a> and send them to the Prometheus adapter. The Prometheus adapter configuration enables a Prometheus instance to scrape Mixer for metrics.</p><p>If the Istio Dashboard or the Prometheus queries dont show the expected metrics, any step of the flow above may present an issue. The following sections provide instructions to troubleshoot each step.</p><h4 id=verify-istio-cni-pods-are-running-if-used>Verify Istio CNI pods are running (if used)</h4><p>The Istio CNI plugin performs the Istio mesh pod traffic redirection in the Kubernetes pod lifecycles network setup phase, thereby removing the <a href=/v1.5/docs/ops/deployment/requirements/>requirement for the <code>NET_ADMIN</code> and <code>NET_RAW</code> capabilities</a> for users deploying pods into the Istio mesh. The Istio CNI plugin replaces the functionality provided by the <code>istio-init</code> container.</p><ol><li><p>Verify that the <code>istio-cni-node</code> pods are running:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ kubectl -n kube-system get pod -l k8s-app=istio-cni-node
</code></pre></li><li><p>If <code>PodSecurityPolicy</code> is being enforced in your cluster, ensure the <code>istio-cni</code> service account can use a <code>PodSecurityPolicy</code> which <a href=/v1.5/docs/ops/deployment/requirements/>allows the <code>NET_ADMIN</code> and <code>NET_RAW</code> capabilities</a></p><h4 id=verify-mixer-is-receiving-report-calls>Verify Mixer is receiving report calls</h4></li></ol><p>Mixer generates metrics to monitor its own behavior. The first step is to check these metrics:</p><ol><li><p>Establish a connection to the Mixer self-monitoring endpoint for the <code>istio-telemetry</code> deployment. In Kubernetes environments, execute the following command:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ kubectl -n istio-system port-forward &lt;istio-telemetry pod&gt; 15014 &amp;
</code></pre></li><li><p>Verify successful report calls. On the Mixer self-monitoring endpoint (<code>http://localhost:15014/metrics</code>), search for <code>grpc_io_server_completed_rpcs</code>. You should see something like:</p><pre><code class=language-plain data-expandlinks=true data-repo=istio>grpc_io_server_completed_rpcs{grpc_server_method=&#34;istio.mixer.v1.Mixer/Report&#34;,grpc_server_status=&#34;OK&#34;} 2532
</code></pre><p>If you do not see any data for <code>grpc_io_server_completed_rpcs</code> with a <code>grpc_server_method="istio.mixer.v1.Mixer/Report"</code>, then Envoy is not calling Mixer to report telemetry.</p></li><li><p>In this case, ensure you integrated the services properly into the mesh. You can achieve this task with either <a href=/v1.5/docs/setup/additional-setup/sidecar-injection/>automatic or manual sidecar injection</a>.</p></li></ol><h4 id=verify-the-mixer-rules-exist>Verify the Mixer rules exist</h4><p>In Kubernetes environments, issue the following command:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ kubectl get rules --all-namespaces
