Service quotas

AWS defines quotas, or limits, for resources, operations, and items in your AWS account. Depending on the number of queries in your dashboard and the number of users accessing the dashboard, you might reach the usage limits for various CloudWatch and CloudWatch Logs resources. Note that quotas are defined per account and per AWS Region. If you’re using multiple Regions or you have set up more than one CloudWatch data source to query against multiple accounts, you must request a quota increase for each account and each Region in which you reach the limit.

For more information, see CloudWatch service quotas.
