1. Open envoyAccessLogService in istio by [enabling **envoyAccessLogService** in ProxyConfig](https://istio.io/docs/reference/config/istio.mesh.v1alpha1/#ProxyConfig).

Upper istio 1.6.0, if istio installed by demo profile, you can open ALS ues command:

istioctl manifest apply --set profile=demo --set meshConfig.defaultConfig.envoyAccessLogService.address=skywalking-oap.skywalking.svc:11800 --set meshConfig.enableEnvoyAccessLogService=true
```
Note:Skywalking oap service is at skywalking namespace, and the port of gRPC service is 11800

Note multiple value，please use `,` symbol split

Notice, only use this when envoy under Istio controlled, also in k8s env. The OAP requires the read right to k8s API server for all pods IPs.

You can use `kubectl logs ${You-OAP-Pod} | grep "K8sALSServiceMeshHTTPAnalysis"` to ensure OAP ALS k8s-mesh analysis has been active.
