AWS Cloud EKS monitoring

SkyWalking leverages OpenTelemetry Collector with AWS Container Insights Receiver to transfer the metrics to OpenTelemetry receiver and into the Meter System.

Data flow

OpenTelemetry Collector fetches metrics from EKS via AWS Container Insights Receiver and pushes metrics to SkyWalking OAP Server via the OpenCensus gRPC Exporter or OpenTelemetry gRPC exporter.
The SkyWalking OAP Server parses the expression with MAL to filter/calculate/aggregate and store the results.

Set up

Deploy amazon/aws-otel-collector with AWS Container Insights Receiver to EKS
Config SkyWalking OpenTelemetry receiver.

EKS Monitoring

AWS Container Insights Receiver 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 instances. The k8s service would be recognized as endpoints.

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:

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
