## Synopsis

- Manages F5 BIG-IP GTM tcp half-open monitors.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---

ignore_down_response
boolean

Choices:
- no
- yes

Specifies that the monitor allows more than one probe attempt per interval.
When `yes`, specifies that 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 that 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`.

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, then the default value will be '*'.
name string / required |  | Monitor name.
parent string | Default: "/Common/tcp_half_open" | 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.
partition string | Default: "Common" | Device partition to manage resources on.
port string |  | Port address part of the IP/port definition. If this parameter is not provided when creating a new monitor, then the default value will be '*'. Note that if specifying an IP address, a value between 1 and 65535 must be specified
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, then 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, then the default value will be `5`.
provider dictionary added in 2.5 |  | 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.
| password 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`. aliases: pass, pwd
| server string / required |  | The BIG-IP host. You may omit this option by setting the environment variable `F5_SERVER`.
| server_port integer | Default: 443 | The BIG-IP server port. You may omit this option by setting the environment variable `F5_SERVER_PORT`.
| ssh_keyfile path |  | Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. You may omit this option by setting the environment variable `ANSIBLE_NET_SSH_KEYFILE`.
| 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

Choices:
- cli
- rest ←

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

| 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

Choices:
- no
- yes ←

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`.

state
string

Choices:
- present ←
- absent

When `present`, ensures that the monitor exists.
When `absent`, ensures the monitor is removed.

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, then the default value will be `120`.

transparent
boolean

Choices:
- no
- yes

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, then the default value will be `no`.

## 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 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.

## Examples

    - name: Create TCP half-open Monitor
      bigip_gtm_monitor_tcp_half_open:
        state: present
        ip: 10.10.10.10
        name: my_monitor
        provider:
          user: admin
          password: secret
          server: lb.mydomain.com
      delegate_to: localhost

    - name: Remove TCP half-open Monitor
      bigip_gtm_monitor_tcp_half_open:
        state: absent
        name: my_monitor
        provider:
          user: admin
          password: secret
          server: lb.mydomain.com
      delegate_to: localhost

    - name: Add half-open monitor for all addresses, port 514
