Synopsis

  • Manages F5 BIG-IP GTM (now BIG-IP DNS) HTTP monitors.

Parameters

Parameter

Comments

ignore_down_response

boolean

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

When true, 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 false, 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, the default value is false.

Choices:

  • false

  • true

interval

integer

The interval specifying how frequently the monitor instance of this template will run.

If this parameter is not provided when creating a new monitor, the default value is 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 is ‘*’.

If this value is an IP address, then a port number must be specified.

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 http parent on the Common partition.

Default: "/Common/http"

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 is ‘*’. If specifying an IP address, you must use a value between 1 and 65535.

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 is 5.

provider

dictionary

added in f5networks.f5_modules 1.0.0

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:

  • false ← (default)

  • true

password

aliases: pass, pwd

string / required

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

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

server

string / required

The BIG-IP host or the BIG-IQ 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 or the BIG-IQ. 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:

  • false

  • true ← (default)

receive

string

The receive string for the monitor call.

reverse

boolean

Instructs the system to mark the target resource down when the test is successful. This setting is useful, for example, if the content on your web site home page is dynamic and changes frequently, you may want to set up a reverse ECV service check that looks for the string Error.

A match for this string means the web server was down.

To use this option, you must specify values for send and receive.

Choices:

  • false

  • true

send

string

The send string for the monitor call.

When creating a new monitor, if this parameter is not provided, the default of GET /\r\n is used.

state

string

When present, ensures the monitor exists.

When absent, ensures the monitor is removed.

Choices:

  • "present" ← (default)

  • "absent"

target_password

string

Specifies the password, if the monitored target requires authentication.

target_username

string

Specifies the user name, if the monitored target requires authentication.

timeout

integer

The number of seconds in which the node or service must 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. You can change this to any number, however, it should be 3 times the interval number of seconds plus 1 second.

If this parameter is not provided when creating a new monitor, then default value is 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 is no false.

Choices:

  • false

  • true

update_password

string

always updates passwords if the target_password is specified.

on_create only sets the password for newly created monitors.

Choices:

  • "always" ← (default)

  • "on_create"

Notes

Note

  • 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.
