Synopsis

Parameters

Parameter Choices/Defaults Comments

availability_requirements

dictionary

If you activate more than one health monitor, specifies the number of health monitors that must receive successful responses in order for the link to be considered available.

at_least

integer

Specifies the minimum number of active health monitors that must be successful before the link is considered up.

This parameter is only relevant when a type of at_least is used.

This parameter will be ignored if a type of either all or require is used.

number_of_probers

integer

Specifies the number of probers that should be used when running probes.

When creating a new virtual server, if this parameter is specified, the number_of_probes parameter must also be specified.

The value of this parameter should always be higher than, or equal to, the value of number_of_probers.

This parameter is only relevant when a type of require is used.

This parameter will be ignored if a type of either all or at_least is used.

number_of_probes

integer

Specifies the minimum number of probes that must succeed for this server to be declared up.

When creating a new virtual server, if this parameter is specified, then the number_of_probers parameter must also be specified.

The value of this parameter should always be lower than, or equal to, the value of number_of_probers.

This parameter is only relevant when a type of require is used.

This parameter will be ignored if a type of either all or at_least is used.

type

string / required

  • all
  • at_least
  • require

Monitor rule type when monitors is specified.

When creating a new pool, if this value is not specified, the default of all will be used.

datacenter

string

Data center to which the server belongs. When creating a new GTM server, this value is required.

devices

raw

Lists the self IP addresses and translations for each device. When creating a new GTM server, this value is required. This list is a complex list that specifies a number of keys.

The name key specifies a name for the device. The device name must be unique per server. This key is required.

The address key contains an IP address, or list of IP addresses, for the destination server. This key is required.

The translation key contains an IP address to translate the address value above to. This key is optional.

Specifying duplicate name fields is a supported means of providing device addresses. In this scenario, the addresses will be assigned to the name's list of addresses.

iquery_options

dictionary

Specifies whether the Global Traffic Manager uses this BIG-IP system to conduct a variety of probes before delegating traffic to it.

allow_path

boolean

  • no
  • yes

Specifies the system verifies the logical network route between a data center server and a local DNS server.

allow_service_check

boolean

  • no
  • yes

Specifies the system verifies that an application on a server is running, by remotely running the application using an external service checker program.

allow_snmp

boolean

  • no
  • yes

Specifies the system checks the performance of a server running an SNMP agent.

limits

dictionary

Specifies resource thresholds or limit requirements at the pool member level.

When you enable one or more limit settings, the system then uses that data to take members in and out of service.

You can define limits for any or all of the limit settings. However, when a member does not meet the resource threshold limit requirement, the system marks the member as unavailable and directs load balancing traffic to another resource.

bits_enabled

boolean

  • no
  • yes

Whether the bits limit it enabled or not.

This parameter allows you to switch on or off the effect of the limit.

bits_limit

integer

Specifies the maximum allowable data throughput rate for the member, in bits per second.

If the network traffic volume exceeds this limit, the system marks the member as unavailable.

connections_enabled

boolean

  • no
  • yes

Whether the current connections limit it enabled or not.

This parameter allows you to switch on or off the effect of the limit.

connections_limit

integer

Specifies the maximum number of concurrent connections, combined, for all of the members.

If the connections exceed this limit, the system marks the server as unavailable.

cpu_enabled

boolean

  • no
  • yes

Whether the CPU limit it enabled or not.

This parameter allows you to switch on or off the effect of the limit.

cpu_limit

integer

Specifies the percent of CPU usage.

If percent of CPU usage goes above the limit, the system marks the server as unavailable.

memory_enabled

boolean

  • no
  • yes

Whether the memory limit it enabled or not.

This parameter allows you to switch on or off the effect of the limit.

memory_limit

integer

Specifies the available memory required by the virtual servers on the server.

If available memory falls below this limit, the system marks the server as unavailable.

packets_enabled

boolean

  • no
  • yes

Whether the packets limit it enabled or not.

This parameter allows you to switch on or off the effect of the limit.

packets_limit

integer

Specifies the maximum allowable data transfer rate for the member, in packets per second.

If the network traffic volume exceeds this limit, the system marks the member as unavailable.

link_discovery

string

  • enabled
  • disabled
  • enabled-no-delete

Specifies whether the system auto-discovers the links for this server. When creating a new GTM server, if this parameter is not specified, the default value disabled is used.

If you set this parameter to enabled or enabled-no-delete, you must also ensure the virtual_server_discovery parameter is also set to enabled or enabled-no-delete.

monitors

list / elements=string

Specifies the health monitors the system currently uses to monitor this resource.

When availability_requirements.type is require, you may only have a single monitor in the monitors list.

name

string / required

The name of the server.

partition

string

Default:

"Common"

Device partition to manage resources on.

prober_fallback

string

  • any
  • inside-datacenter
  • outside-datacenter
  • inherit
  • pool
  • none

Specifies the type of prober to use to monitor this server's resources when the preferred prober is not available.

This option is ignored in TMOS version 12.x.

From TMOS version 13.x and up, when prober_preference is set to pool a prober_pool parameter must be specified.

The choices are mutually exclusive with prober_preference parameter, with the exception of the any-available or none options.

prober_pool

string

Specifies the name of the prober pool to use to monitor this server's resources.

In TMOS version 13.x and later, this parameter is mandatory when prober_preference is set to pool.

The format of the name can be either be prepended by partition (/Common/foo), or specified just as an object name (foo).

In TMOS version 12.x, prober_pool can be set to an empty string to revert to default setting of inherit.

prober_preference

string

  • inside-datacenter
  • outside-datacenter
  • inherit
  • pool

Specifies the type of prober to use to monitor this server's resources.

This option is ignored in TMOS version 12.x.

From TMOS version 13.x and up, when prober_preference is set to pool a prober_pool parameter must be specified.

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.

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.
