AWS CloudWatch

You can use the metrics for monitoring and to drive auto-scaling through alerts.

Caution: Exporting custom metrics may incur significant Monitoring costs. Please review Amazon's CloudWatch pricing. By default no metrics are exported; change that using --enable_cloudwatch and --cloudwatch_metrics_filter.

Configuration

  1. Make sure the IAM account has these permissions:

    IAM Permissions
    1
2
3
    "Action": [
    "cloudwatch:PutMetricData"
],

  2. Update the service configuration.

    For example:

    Text Only
    1
2
3
4
    --enable_cloudwatch=true
--cloudwatch_region=eu-central-1
--cloudwatch_namespace=Engflow
--cloudwatch_metrics_filter=used_executors

    See the --cloudwatch_* flags for details.

  3. Update the cluster.

    Bash
    1
    terraform apply

Reducing costs

With --cloudwatch_metrics_filter you can select exactly which metrics are exported. (By default no metric is exported.) Reporting more metrics may increase your monitoring bill; consult the AWS CloudWatch pricing page.
