bigip_gtm_monitor_tcp – Manages F5 BIG-IP GTM tcp monitors

New in version 2.6.

Synopsis

  • Manages F5 BIG-IP GTM tcp monitors.

Requirements

The below requirements are needed on the host that executes this module.

  • f5-sdk >= 3.0.16

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
-
The interval specifying how frequently the monitor instance of this template will run.
If this parameter is not provided when creating a new monitor, then the default value will be 30.
This value must be less than the timeout value.
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 '*'.
If this value is an IP address, then a port number must be specified.
name
- / required
Monitor name.
parent
-
Default:
/Common/tcp
The parent template of this monitor template. Once this value has been set, it cannot be changed. By default, this value is the tcp parent on the Common partition.
partition
-
Default:
Common
Device partition to manage resources on.
password
- / 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
port
-
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_timeout
-
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
-
added in 2.5
Default:
None
A dict object containing connection details.
password
- / 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
- / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
-
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
ssh_keyfile
-
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
-
Default:
10
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
- / required
    Choices:
  • rest
  • cli ←
Configures the transport connection to use when connecting to the remote device.
user
- / 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.
receive
-
The receive string for the monitor call.
reverse
boolean
    Choices:
  • no
  • yes
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 that the web server was down.
To use this option, you must specify values for send and receive.
send
-
The send string for the monitor call.
server
- / required
The BIG-IP host.
You may omit this option by setting the environment variable F5_SERVER.
server_port
-
added in 2.2
Default:
443
The BIG-IP server port.
You may omit this option by setting the environment variable F5_SERVER_PORT.
state
-
    Choices:
  • present ←
  • absent
When present, ensures that the monitor exists.
When absent, ensures the monitor is removed.
timeout
-
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 number to any number you want, 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 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.
user
- / 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
added in 2.0
    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.

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.
