module: bigip_apm_policy_fetch
short_description: Exports the APM policy or APM access profile from remote nodes.
description:
- Exports the apm policy or APM access profile from remote nodes.
version_added: 2.8
options:
name:
description:
- The name of the APM policy or APM access profile exported to create a file on the remote device for downloading.
required: True
dest:
description:
- A directory to save the file into.
type: path
file:
description:
- The name of the file to be created on the remote device for downloading.
type:
description:
- Specifies the type of item to export from device.
choices:
- profile_access
- access_policy
default: profile_access
force:
description:
- If C(no), the file will only be transferred if it does not exist in the the destination.
default: yes
type: bool
partition:
description:
- Device partition to which contain APM policy or APM access profile to export.
default: Common
notes:
- Due to ID685681 it is not possible to execute ng_* tools via REST api on v12.x and 13.x, once this is fixed
this restriction will be removed.
- Requires BIG-IP >= 14.0.0
