Synopsis

  • Manages F5 BIG-IP GTM (now BIG-IP DNS) TCP half-open monitors.

Parameters

Parameter

Comments

ignore_down_response

boolean

Specifies that the monitor allows more than one probe attempt per interval.

When yes, specifies the monitor ignores down responses for the duration of the monitor timeout. Once the monitor timeout is reached without the system receiving an up response, the system marks the object down.

When no, specifies the monitor immediately marks an object down when it receives a down response.

When creating a new monitor, if this parameter is not provided, then the default value will be no.

Choices:

  • no

  • yes

interval

integer

Specifies, in seconds, the frequency at which the system issues the monitor check when either the resource is down or the status of the resource is unknown.

When creating a new monitor, if this parameter is not provided, then the default value will be 30. This value must be less than the timeout value.

ip

string

IP address part of the IP/port definition. If this parameter is not provided when creating a new monitor, the default value will be ‘*’.

name

string / required

Monitor name.

parent

string

The parent template of this monitor template. Once this value has been set, it cannot be changed. By default, this value is the tcp_half_open parent on the Common partition.

Default: “/Common/tcp_half_open”

partition

string

Device partition to manage resources on.

Default: “Common”

port

string

Port address part of the IP/port definition. If this parameter is not provided when creating a new monitor, the default value will be ‘*’. Note that if using an IP address, you must specify a value between 1 and 65535.

probe_attempts

integer

Specifies the number of times the system attempts to probe the host server, after which the system considers the host server down or unavailable.

When creating a new monitor, if this parameter is not provided, the default value will be 3.

probe_interval

integer

Specifies the number of seconds the big3d process waits before sending out a subsequent probe attempt when a probe fails and multiple probe attempts have been requested.

When creating a new monitor, if this parameter is not provided, then the default value will be 1.

probe_timeout

integer

Specifies the number of seconds after which the system times out the probe request to the system.

When creating a new monitor, if this parameter is not provided, the default value will be 5.

provider

dictionary

added in 1.0.0 of f5networks.f5_modules

A dict object containing connection details.

auth_provider

string

Configures the auth provider for to obtain authentication tokens from the remote device.

This option is really used when working with BIG-IQ devices.

no_f5_teem

boolean

If yes, TEEM telemetry data is not sent to F5.

You may omit this option by setting the environment variable F5_TELEMETRY_OFF.

Previously used variable F5_TEEM is deprecated as its name was confusing.

Choices:

  • no ← (default)

  • yes

password

aliases: pass, pwd

string / required

The password for the user account used to connect to the BIG-IP.

You may omit this option by setting the environment variable F5_PASSWORD.

server

string / required

The BIG-IP host.

You may omit this option by setting the environment variable F5_SERVER.

server_port

integer

The BIG-IP server port.

You may omit this option by setting the environment variable F5_SERVER_PORT.

Default: 443

timeout

integer

Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.

transport

string

Configures the transport connection to use when connecting to the remote device.

Choices:

  • rest ← (default)

user

string / required

The username to connect to the BIG-IP with. This user must have administrative privileges on the device.

You may omit this option by setting the environment variable F5_USER.

validate_certs

boolean

If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.

You may omit this option by setting the environment variable F5_VALIDATE_CERTS.

Choices:

  • no

  • yes ← (default)

state

string

When present, ensures the monitor exists.

When absent, ensures the monitor is removed.

Choices:

  • present ← (default)

  • absent

timeout

integer

Specifies the number of seconds the target has in which to respond to the monitor request.

If the target responds within the set time period, it is considered up.

If the target does not respond within the set time period, it is considered down.

When this value is set to 0 (zero), the system uses the interval from the parent monitor.

When creating a new monitor, if this parameter is not provided, the default value will be 120.

transparent

boolean

Specifies whether the monitor operates in transparent mode.

A monitor in transparent mode directs traffic through the associated pool members or nodes (usually a router or firewall) to the aliased destination (that is, it probes the ip-port combination specified in the monitor).

If the monitor cannot successfully reach the aliased destination, the pool member or node through which the monitor traffic was sent is marked down.

When creating a new monitor, if this parameter is not provided, the default value will be no.

Choices:

  • no

  • yes

Notes

Note

  • Requires BIG-IP software version >= 12

  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.

  • Requires BIG-IP software version >= 12.

  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the f5networks.f5_modules.bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
