availability_requirements
-
added in 2.6
Specifies, if you activate more than one health monitor, the number of health monitors that must receive successful responses in order for the link to be considered available.
at_least
-
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
-
Specifies the number of probers that should be used when running probes.
When creating a new virtual server, if this parameter is specified, then 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
-
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.

Notes

Note

  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.
  • Requires the f5-sdk Python package on the host. This is as easy as pip install f5-sdk.
  • 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 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.
