Parameters

Parameter	Choices/Defaults	Comments
admin_state_up boolean	Choices: no yes ←	The admin state of the helath monitor true for up or false for down
api_timeout integer		How long should the socket layer wait before timing out for API calls. If this is omitted, nothing will be passed to the requests library.
auth dictionary		Dictionary containing auth information as needed by the cloud's auth plugin strategy. For the default password plugin, this would contain auth_url, username, password, project_name and any information about domains (for example, user_domain_name or project_domain_name) if the cloud supports them. For other plugins, this param will need to contain whatever parameters that auth plugin requires. This parameter is not needed if a named cloud is provided or OpenStack OS_* environment variables are present.
auth_type string		Name of the auth plugin to use. If the cloud uses something other than password authentication, the name of the plugin should be indicated here and the contents of the auth parameter should be updated accordingly.
availability_zone string		Ignored. Present for backwards compatibility
ca_cert string		A path to a CA Cert bundle that can be used as part of verifying SSL API requests. aliases: cacert
client_cert string		A path to a client certificate to use as part of the SSL transaction. aliases: cert
client_key string		A path to a client key to use as part of the SSL transaction. aliases: key
cloud raw		Named cloud or cloud config to operate against. If cloud is a string, it references a named cloud config as defined in an OpenStack clouds.yaml file. Provides default values for auth and auth_type. This parameter is not needed if auth is provided or if OpenStack OS_* environment variables are present. If cloud is a dict, it contains a complete cloud configuration like would be in a section of clouds.yaml.
delay string / required		the interval, in seconds, between health checks.
expected_codes string	Default: 200	The list of HTTP status codes expected in response from the member to declare it healthy. Specify one of the following values A single value, such as 200 A list, such as 200, 202 A range, such as 200-204
http_method string	Choices: GET ← CONNECT DELETE HEAD OPTIONS PATCH POST PUT TRACE	The HTTP method that the health monitor uses for requests. One of CONNECT, DELETE, GET, HEAD, OPTIONS, PATCH, POST, PUT, or TRACE. The default is GET.
interface string	Choices: admin internal public ←	Endpoint URL type to fetch from the service catalog. aliases: endpoint_type
max_retries string / required		The number of successful checks before changing the operating status of the member to ONLINE.
max_retries_down string	Default: 3	The number of allowed check failures before changing the operating status of the member to ERROR. A valid value is from 1 to 10. The default is 3.
name string / required		Name that has to be given to the health monitor
pool string / required		The pool name or id to monitor by the health monitor.
region_name string		Name of the region.
resp_timeout integer / required		The time, in seconds, after which a health check times out. Must be less than delay
state string	Choices: present ← absent	Should the resource be present or absent.
timeout integer	Default: 180	How long should ansible wait for the requested resource.
type string	Choices: HTTP ← HTTPS PING SCTP TCP TLS-HELLO UDP-CONNECT	One of HTTP, HTTPS, PING, SCTP, TCP, TLS-HELLO, or UDP-CONNECT.
url_path string	Default: "/"	The HTTP URL path of the request sent by the monitor to test the health of a backend member. Must be a string that begins with a forward slash (/). The default URL path is /.
validate_certs boolean	Choices: no ← yes	Whether or not SSL API requests should be verified. Before Ansible 2.3 this defaulted to yes. aliases: verify
wait boolean	Choices: no yes ←	Should ansible wait until the requested resource is complete.

Notes

Note

• The standard OpenStack environment variables, such as OS_USERNAME may be used instead of providing explicit values.

• Auth information is driven by openstacksdk, which means that values can come from a yaml config file in /etc/ansible/openstack.yaml, /etc/openstack/clouds.yaml or ~/.config/openstack/clouds.yaml, then from standard environment variables, then finally by explicit parameters in plays. More information can be found at https://docs.openstack.org/openstacksdk/
