Provides a CloudWatch dashboard to allow monitoring AWS resources. The resources supported consist of:

• Elastic Container Service (ECS) containers.
• Relational Database Service (RDS) instances.

The CloudWatch dashboard widgets for ECS containers consists of two widgets forming a single row:

1. Average CPU utilization (as a percentage) for the specified containers.
2. Average memory utilization (as a percentage) for the specified containers.

The CloudWatch dashboard widgets for RDS instances also consists of two widgets forming a single row:

1. Average read and write IOPS for the specified RDS instance.
2. Free storage space for the specified RDS instance.

The X axis range for the CloudWatch dashboard widgets is six hours.

The CloudWatch console allows a user to inspect a widget by enlarging the widget, adjusting ranges and metrics, etc. See Using Amazon CloudWatch Dashboards for details.

  dashboard_name = "JRR dashboard"
  
  ecs_cluster = "jrr"
  
  ecs_containers = [

  rds_instance = "jrr-db"
}

The following arguments are supported:

• dashboard_name - (Required) Dashboard name.

• ecs_cluster - (Required) Name of ECS cluster holding the service containers to be monitored.

• ecs_containers - (Optional) List of ECS containers to be displayed on dashboard.

• period – (Optional) Period plotted by dashboard widgets. The default is 300 (a five-minute period

• rds_free_storage_max – (Optional) Maximum free storage value plotted on Y axis. By default, CloudWatch chooses the maximum Y value based on the data values in the period.

• rds_iops_max – (Optional) Maximum IOPS value plotted on Y axis. By default, CloudWatch chooses the maximum Y value based on the data values in the period.

• rds_instance – (Optional) RDS instance to be displayed on dashboard. NOTE: Currently, this module supports only one RDS instance per dashboard.

The following attributes are exported:

• dashboard_arn – ARN of dashboard provided by this module.
