bigip_monitor_dns – Manage DNS monitors on a BIG-IP¶
New in version 2.7.
Synopsis¶
Manages DNS monitors on a BIG-IP.
Parameters¶
Parameter | Choices/Defaults | Comments | |
---|---|---|---|
accept_rcode
string
|
|
Specifies the RCODE required in the response for an up status.
When creating a new monitor, if this parameter is not specified, the default value is
no-error .When
no-error , specifies that the status of the node will be marked up if the received DNS message has no error.When
anything , specifies that the status of the node will be marked up irrespective of the RCODE in the DNS message received.If this parameter is set to
anything , it will disregard the receive string, and nullify it if the monitor is being updated. |
|
adaptive
boolean
|
|
Specifies whether adaptive response time monitoring is enabled for this monitor.
When
yes , the monitor determines the state of a service based on how divergent from the mean latency a monitor probe for that service is allowed to be. Also, values for the allowed_divergence , adaptive_limit , and and sampling_timespan will be enforced.When
disabled , the monitor determines the state of a service based on the interval , up_interval , time_until_up , and timeout monitor settings. |
|
adaptive_limit
integer
|
Specifies the absolute number of milliseconds that may not be exceeded by a monitor probe, regardless of
allowed_divergence setting, for a probe to be considered successful.This value applies regardless of the value of the
allowed_divergence setting.While this value can be configured when
adaptive is no , it will not take effect on the system until adaptive is yes . |
||
allowed_divergence_type
string
|
|
When specifying a new monitor, if
adaptive is yes , the default is relative When
absolute , the number of milliseconds the latency of a monitor probe can exceed the mean latency of a monitor probe for the service being probed. In typical cases, if the monitor detects three probes in a row that miss the latency value you set, the pool member or node is marked down.When
relative , the percentage of deviation the latency of a monitor probe can exceed the mean latency of a monitor probe for the service being probed. |
|
allowed_divergence_value
integer
|
When specifying a new monitor, if
adaptive is yes , and type is relative , the default is 25 percent. |
||
answer_section_contains
string
|
|
Specifies the type of DNS query that the monitor sends.
When creating a new monitor, if this value is not specified, the default value is
query-type .When
query-type , specifies that the response should contain at least one answer of which the resource record type matches the query type.When
any-type , specifies that the DNS message should contain at least one answer.When
anything , specifies that an empty answer is enough to mark the status of the node up. |
|
description

|
||
interval
integer
|

||
ip

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

||
manual_resume
boolean
|
|
Specifies whether the system automatically changes the status of a resource to enabled at the next successful monitor check.
If you set this option to
yes , you must manually re-enable the resource before the system can use it for load balancing connections.When creating a new monitor, if this parameter is not specified, the default value is
no .When
yes , specifies that you must manually re-enable the resource after an unsuccessful monitor check.When
no , specifies that the system automatically changes the status of a resource to enabled at the next successful monitor check. |

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 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.
