AWS Health Dashboard notificaciones de Auto Scaling de aplicaciones

Para ayudarle a administrar los eventos de escalado con errores, AWS Health Dashboard proporciona soporte las notificaciones emitidas por Auto Scaling de aplicaciones. Actualmente solo están disponibles los eventos de escalado horizontal específicos de sus recursos de DynamoDB.

El AWS Health Dashboard forma parte del servicio AWS Health. No precisa configuración y cualquier usuario autenticado en su cuenta puede consultarlo. Para obtener más información, consulte Introducción a AWS Health Dashboard.

Si sus recursos de DynamoDB no se están escalando horizontalmente debido a los límites de cuota del servicio de DynamoDB, recibirá un mensaje similar al siguiente. Si recibe este mensaje, deberá tratarlo como una alarma para tomar medidas.

  Hello,

  A scaling action has attempted to scale out your DynamoDB resources in the
  eu-west-1 region. This operation has been prevented because it would have exceeded a
  table-level write throughput limit (Provisioned mode). This limit restricts the
  provisioned write capacity of the table and all of its associated global secondary
  indexes. To address the issue, refer to the Amazon DynamoDB Developer Guide for
  current limits and how to request higher limits [1].

  To identify your DynamoDB resources that are impacted, use the 
  describe-scaling-activities command or the DescribeScalingActivities operation [2][3].
  Look for a scaling activity with StatusCode "Failed" and a StatusMessage similar to
  "Failed to set write capacity units to 45000. Reason: The requested WriteCapacityUnits,
  45000, is above the per table maximum for the account in eu-west-1. Per table maximum:
  40000." You can also view these scaling activities from the Capacity tab of your tables 
  in the AWS Management Console for DynamoDB. 

  We strongly recommend that you address this issue to ensure that your tables
  are prepared to handle increases in traffic. This notification is sent only once in 
  each 12 hour period, even if another failed scaling action occurs.
