3.2. Logging with Amazon CloudWatch

Procedure

• Modify the logging level by including the environment variable LOG_LEVEL in your custom resource as follows:

  spec:
    # Other fields omitted
    application:
      extraEnvs:
        envs:
          - name: LOG_LEVEL
            value: debug

Procedure

• Modify the logging level by adding the environment variable LOG_LEVEL to your Helm chart values.yaml file:

  upstream:
    backstage:
      # --- Truncated ---
      extraEnvVars:
        - name: LOG_LEVEL
          value: debug

Prerequisites

• CloudWatch Container Insights is used to capture logs and metrics for Amazon Elastic Kubernetes Service. For more information, see Logging for Amazon Elastic Kubernetes Service documentation.
• To capture the logs and metrics, install the Amazon CloudWatch Observability EKS add-on in your cluster. Following the setup of Container Insights, you can access container logs using Logs Insights or Live Tail views.

• CloudWatch names the log group where all container logs are consolidated in the following manner:

  /aws/containerinsights/<cluster_name>/application

Procedure

• To retrieve logs from the Developer Hub instance, run a query such as:

  fields @timestamp, @message, kubernetes.container_name
  | filter kubernetes.container_name in ["install-dynamic-plugins", "backstage-backend"]
