Definitions

Name	Description
CloudError	An error response from the service.
CloudErrorBody	An error response from the service.
Probe	A load balancer probe.
ProbeNoHealthyBackendsBehavior	Determines how new connections are handled by the load balancer when all backend instances are probed down.
ProbeProtocol	The protocol of the end point. If 'Tcp' is specified, a received ACK is required for the probe to be successful. If 'Http' or 'Https' is specified, a 200 OK response from the specifies URI is required for the probe to be successful.
ProvisioningState	The current provisioning state.
SubResource	Reference to another subresource.

CloudError

An error response from the service.

Name	Type	Description
error	CloudErrorBody	Cloud error body.

CloudErrorBody

An error response from the service.

Name	Type	Description
code	string	An identifier for the error. Codes are invariant and are intended to be consumed programmatically.
details	CloudErrorBody[]	A list of additional details about the error.
message	string	A message describing the error, intended to be suitable for display in a user interface.
target	string	The target of the particular error. For example, the name of the property in error.

Probe

A load balancer probe.

Name	Type	Description
etag	string	A unique read-only string that changes whenever the resource is updated.
id	string	Resource ID.
name	string	The name of the resource that is unique within the set of probes used by the load balancer. This name can be used to access the resource.
properties.intervalInSeconds	integer	The interval, in seconds, for how frequently to probe the endpoint for health status. Typically, the interval is slightly less than half the allocated timeout period (in seconds) which allows two full probes before taking the instance out of rotation. The default value is 15, the minimum value is 5.
properties.loadBalancingRules	SubResource[]	The load balancer rules that use this probe.
properties.noHealthyBackendsBehavior	ProbeNoHealthyBackendsBehavior	Determines how new connections are handled by the load balancer when all backend instances are probed down.
properties.numberOfProbes	integer	The number of probes where if no response, will result in stopping further traffic from being delivered to the endpoint. This values allows endpoints to be taken out of rotation faster or slower than the typical times used in Azure.
properties.port	integer	The port for communicating the probe. Possible values range from 1 to 65535, inclusive.
properties.probeThreshold	integer	The number of consecutive successful or failed probes in order to allow or deny traffic from being delivered to this endpoint. After failing the number of consecutive probes equal to this value, the endpoint will be taken out of rotation and require the same number of successful consecutive probes to be placed back in rotation.
properties.protocol	ProbeProtocol	The protocol of the end point. If 'Tcp' is specified, a received ACK is required for the probe to be successful. If 'Http' or 'Https' is specified, a 200 OK response from the specifies URI is required for the probe to be successful.
properties.provisioningState	ProvisioningState	The provisioning state of the probe resource.
properties.requestPath	string	The URI used for requesting health status from the VM. Path is required if a protocol is set to http. Otherwise, it is not allowed. There is no default value.
type	string	Type of the resource.

ProbeNoHealthyBackendsBehavior

Determines how new connections are handled by the load balancer when all backend instances are probed down.

Name	Type	Description
AllProbedDown	string	No new flows will be sent to the backend pool.
AllProbedUp	string	When all backend instances are probed down, incoming packets will be sent to all instances.

ProbeProtocol

The protocol of the end point. If 'Tcp' is specified, a received ACK is required for the probe to be successful. If 'Http' or 'Https' is specified, a 200 OK response from the specifies URI is required for the probe to be successful.

Name	Type	Description
Http	string
Https	string
Tcp	string

ProvisioningState

The current provisioning state.

Name	Type	Description
Deleting	string
Failed	string
Succeeded	string
Updating	string

SubResource

Reference to another subresource.

Name	Type	Description
id	string	Resource ID.
