SkyWalking leverages OpenTelemetry Collector with [AWS Container Insights Receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/awscontainerinsightreceiver/README.md) to transfer the metrics to
[OpenTelemetry receiver](opentelemetry-receiver.md) and into the [Meter System](./../../concepts-and-designs/meter.md).
### Data flow
1. OpenTelemetry Collector fetches metrics from EKS via [AWS Container Insights Receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/awscontainerinsightreceiver/README.md) and pushes metrics to SkyWalking OAP Server via the OpenCensus gRPC Exporter or OpenTelemetry gRPC exporter.
2. The SkyWalking OAP Server parses the expression with [MAL](../../concepts-and-designs/mal.md) to filter/calculate/aggregate and store the results.
### Set up
1. Deploy [amazon/aws-otel-collector](https://hub.docker.com/r/amazon/aws-otel-collector) with [AWS Container Insights Receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/awscontainerinsightreceiver/README.md) to EKS
[AWS Container Insights Receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/awscontainerinsightreceiver/README.md) provides multiple dimensions metrics for EKS cluster, node, service, etc.
Accordingly, SkyWalking observes the status, and payload of the EKS cluster, which is cataloged as a `LAYER: AWS_EKS``Service` in the OAP. Meanwhile, the k8s nodes would be recognized as `LAYER: AWS_EKS``instance`s. The k8s service would be recognized as `endpoint`s.
#### Specify Job Name
SkyWalking distinguishes AWS Cloud EKS metrics by attributes `job_name`, which value is `aws-cloud-eks-monitoring`.
You could leverage OTEL Collector processor to add the attribute as follows:
```yaml
processors:
resource/job-name:
attributes:
-key:job_name
value:aws-cloud-eks-monitoring
action:insert
```
Notice, if you don't specify `job_name` attribute, SkyWalking OAP will ignore the metrics
