**To obtain the capacity used by a set of rules**
The following ``check-capacity`` retrieves the capacity requirements for a rule set that contains a rate-based rule statement, and an AND rule statement that contains nested rules. ::
aws wafv2 check-capacity \
--scope REGIONAL \
--rules file://waf-rule-list.json \
--region us-west-2
Contents of `file://waf-rule-list.json`::
