Historical metrics reports have the following limits:

**Service quotas**

When service quotas are breached, the following error message is displayed: *Report cannot be saved*. For more information about these quotas, see [Connect Customer service quotas](amazon-connect-service-limits.md)

**Data only for active queues**
+ You can get data only for active queues. A queue is inactive if there are no contacts in the queue and no agents available.

**Query data for three days at a time, for the past 2 days**
