|
||
you are expecting to see reported and 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=/v1.1/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 don’t show the expected metrics, any step of the flow above may present an issue. The following sections provide instructions to troubleshoot each step.</p><h2 id=verify-mixer-is-receiving-report-calls>Verify Mixer is receiving Report calls</h2><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>$ kubectl -n istio-system port-forward <istio-telemetry pod> 15014 &
|
||
</code></pre></li><li><p>Verify successful report calls. On the Mixer self-monitoring endpoint, search for <code>grpc_io_server_completed_rpcs</code>. You should see something like:</p><pre><code class=language-plain data-expandlinks=true>grpc_io_server_completed_rpcs{grpc_server_method="istio.mixer.v1.Mixer/Report",grpc_server_status="OK"} 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=/v1.1/docs/setup/kubernetes/additional-setup/sidecar-injection/>automatic or manual sidecar injection</a>.</p></li></ol><h2 id=verify-the-mixer-rules-exist>Verify the Mixer rules exist</h2><p>In Kubernetes environments, issue the following command:</p><pre><code class=language-bash data-expandlinks=true>$ kubectl get rules --all-namespaces
