Querying Flow Logs

Function

This API is used to query the flow log list.

Constraints

There are some constraints:

  • Filtering query is supported. The supported filtering criteria include resource_type, resource_id, and enterprise_project_id. You can query multiple resources at a time or use combined criteria to query resources.

  • Pagination query is supported. You can use limit and marker together for query.

  • Only sorting by a single field (id, name, or state) is supported.

Calling Method

For details, see Calling APIs.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the following required identity policy-based permissions. For details about the required permissions, see Permissions Policies and Supported Actions.
