# Sending Envoy Metrics to SkyWalking OAP Server Example
|
|
|
|
This is an example of sending [Envoy Stats](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/observability/statistics#arch-overview-statistics) to SkyWalking OAP server
|
|
through [Metric Service](https://www.envoyproxy.io/docs/envoy/latest/api-v2/config/metrics/v2/metrics_service.proto).
|
|
|
|
## Running the example
|
|
|
|
The example requires `docker` and `docker-compose` to be installed in your local. It fetches images from Docker Hub.
|
|
|
|
Note that in ths setup, we override the [`log4j2.xml`](log4j2.xml) config to set the `org.apache.skywalking.oap.server.receiver.envoy` logger level to `DEBUG`. This enables us to see the messages sent by Envoy to SkyWalking OAP server.
|
|
|
|
```
|
|
$ make up
|
|
$ docker-compose logs -f skywalking
|
|
$ # Please wait for a moment until SkyWalking is ready and Envoy starts sending the stats. You will see similar messages like the following:
|
|
