-3. Active ALS k8s-mesh analysis, set system env variable
`SW_ENVOY_METRIC_ALS_HTTP_ANALYSIS`=`k8s-mesh`
+3. Active ALS analyzer, there are two available analyzers, `k8s-mesh` and
`mx-mesh`,
+`k8s-mesh` uses the metadata from Kubernetes cluster, hence in this analyzer
OAP needs access roles to `Pod`, `Service`, and `Endpoints`;
+`mx-mesh` uses the Envoy metadata exchange mechanism to get the service name,
etc.,
+this analyzer requires Istio to enable the metadata exchange filter(you can
enable it by
+`--set telemetry.v2.enabled=true`, or if you're using Istio 1.7+ and
installing it with profile `demo`/`preview`,
Review comment:
1.7+ enabled in default? If so, good to me.
