-<p>The SkyWalking adapter uses the <code>Istio bypass</code> adapter to collect metrics and make them available to
-<a href="https://skywalking.apache.org/">Apache SkyWalking</a>. SkyWalking provides a topology map and metrics graph 
-to visualize the whole mesh.</p>
-
-<p>This adapter supports the <a href="https://istio.io/docs/reference/config/policy-and-telemetry/templates/metric/">metric template</a>.</p>
