module: bigip_remote_syslog
short_description: Manipulate remote syslog settings on a BIG-IP
description:
- Manipulate remote syslog settings on a BIG-IP.
version_added: 2.5
options:
remote_host:
description:
- Specifies the IP address, or hostname, for the remote system to
which the system sends log messages.
required: True
remote_port:
description:
- Specifies the port that the system uses to send messages to the
remote logging server. When creating a remote syslog, if this parameter
is not specified, the default value C(514) is used.
local_ip:
description:
- Specifies the local IP address of the system that is logging. To
provide no local IP, specify the value C(none). When creating a
remote syslog, if this parameter is not specified, the default value
C(none) is used.
notes:
- Requires the f5-sdk Python package on the host. This is as easy as pip
install f5-sdk.
- Requires the netaddr Python package on the host. This is as easy as pip
install netaddr.
extends_documentation_fragment: f5
requirements:
- f5-sdk >= 2.2.0
