selectionCriteria

Use this parameter to apply the new policy to a subset of log groups in the account.

Specifying selectionCriteria is valid only when you specify SUBSCRIPTION_FILTER_POLICY, FIELD_INDEX_POLICY or TRANSFORMER_POLICYfor policyType.

If policyType is SUBSCRIPTION_FILTER_POLICY, the only supported selectionCriteria filter is LogGroupName NOT IN []

If policyType is FIELD_INDEX_POLICY or TRANSFORMER_POLICY, the only supported selectionCriteria filter is LogGroupNamePrefix

The selectionCriteria string can be up to 25KB in length. The length is determined by using its UTF-8 bytes.

Using the selectionCriteria parameter with SUBSCRIPTION_FILTER_POLICY is useful to help prevent infinite loops. For more information, see Log recursion prevention.
