+# Configuring Envoy to send metrics to SkyWalking
+
+In order to let Envoy to send metrics to SkyWalking, we need to feed Envoy with a configuration which contains `stats_sinks` that includes `envoy.metrics_service`.
+This `envoy.metrics_service` should be configured as a [`config.grpc_service`](https://www.envoyproxy.io/docs/envoy/latest/api-v2/api/v2/core/grpc_service.proto#envoy-api-msg-core-grpcservice) entry.
+
+The interesting parts of the config is shown in the config below:
+
+```yaml
+stats_sinks:
+ - name: envoy.metrics_service
+ config:
+ grpc_service:
+ # Note: we can use google_grpc implementation as well.
+ envoy_grpc:
+ cluster_name: skywalking_service

+ # This is the port where SkyWalking serving the Envoy Metrics Service gRPC stream.
+ port_value: 11800
+```
+
+A more complete static configuration, can be observed here [config.yaml].
+
+Note that Envoy can also be configured dynamically through [xDS Protocol](https://github.com/envoyproxy/data-plane-api/blob/master/XDS_PROTOCOL.md).
+
+# Metrics data
+
+Some of the Envoy statitics are listed in this [list](https://www.envoyproxy.io/docs/envoy/latest/configuration/statistics). While a sample data that contains idetifier can be found [here](identify.json), while the metrics only can be observed [here](https://www.envoyproxy.io/docs/envoy/latest/configuration/statistics).
