LbPool (schema)

Name	Description	Type	Notes
_create_time	Timestamp of resource creation	EpochMsTimestamp	Readonly Sortable
_create_user	ID of the user who created this resource	string	Readonly
_last_modified_time	Timestamp of last modification	EpochMsTimestamp	Readonly Sortable
_last_modified_user	ID of the user who last modified this resource	string	Readonly
_links	References related to this resource The server will populate this field when returing the resource. Ignored on PUT and POST.	array of ResourceLink	Readonly
_protection	Indicates protection status of this resource Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true. UNKNOWN - the _protection field could not be determined for this entity.	string	Readonly
_revision	Generation of this resource config The _revision property describes the current revision of the resource. To prevent clients from overwriting each other's changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected.	int
_schema	Schema for this resource	string	Readonly
_self	Link to this resource	SelfResourceLink	Readonly
_system_owned	Indicates system owned resource	boolean	Readonly
active_monitor_ids	active monitor identifier list In case of active healthchecks, load balancer itself initiates new connections (or sends ICMP ping) to the servers periodically to check their health, completely independent of any data traffic. Active healthchecks are disabled by default and can be enabled for a server pool by binding a health monitor to the pool. If multiple active monitors are configured, the pool member status is UP only when the health check status for all the monitors are UP. The property is deprecated as NSX-T Load Balancer is deprecated.	array of string	Deprecated
algorithm	pool balancing algorithm for backend pool members Load balancing algorithm, configurable per pool controls how the incoming connections are distributed among the members.	PoolAlgorithm	Default: "ROUND_ROBIN"
description	Description of this resource	string	Maximum length: 1024 Sortable
display_name	Identifier to use when displaying entity in logs or GUI Defaults to ID if not set	string	Maximum length: 255 Sortable
id	Unique identifier of this resource	string	Sortable
member_group	Load balancer member setting with grouping object Load balancer pool support grouping object as dynamic pool members. When member group is defined, members setting should not be specified.	PoolMemberGroup
members	load balancer pool members Server pool consists of one or more pool members. Each pool member is identified, typically, by an IP address and a port.	array of PoolMember
min_active_members	minimum number of active pool members to consider pool as active A pool is considered active if there are at least certain minimum number of members.	integer	Minimum: 1 Maximum: 2147483647 Default: "1"
passive_monitor_id	passive monitor identifier Passive healthchecks are disabled by default and can be enabled by attaching a passive health monitor to a server pool. Each time a client connection to a pool member fails, its failed count is incremented. For pools bound to L7 virtual servers, a connection is considered to be failed and failed count is incremented if any TCP connection errors (e.g. TCP RST or failure to send data) or SSL handshake failures occur. For pools bound to L4 virtual servers, if no response is received to a TCP SYN sent to the pool member or if a TCP RST is received in response to a TCP SYN, then the pool member is considered to have failed and the failed count is incremented. The property is deprecated as NSX-T Load Balancer is deprecated.	string	Deprecated
resource_type	Must be set to the value LbPool	string
snat_translation	snat translation configuration Depending on the topology, Source NAT (SNAT) may be required to ensure traffic from the server destined to the client is received by the load balancer. SNAT can be enabled per pool. If SNAT is not enabled for a pool, then load balancer uses the client IP and port (spoofing) while establishing connections to the servers. This is referred to as no-SNAT or TRANSPARENT mode. The property is deprecated as NSX-T Load Balancer is deprecated.	LbSnatTranslation (Abstract type: pass one of the following concrete types) LbSnatAutoMap LbSnatIpPool	Deprecated
tags	Opaque identifiers meaningful to the API user	array of Tag	Maximum items: 30
tcp_multiplexing_enabled	TCP multiplexing enable flag TCP multiplexing allows the same TCP connection between load balancer and the backend server to be used for sending multiple client requests from different client TCP connections. The property is deprecated as NSX-T Load Balancer is deprecated.	boolean	Deprecated Default: "False"
tcp_multiplexing_number	maximum number of TCP connections for multiplexing The maximum number of TCP connections per pool that are idly kept alive for sending future client requests. The property is deprecated as NSX-T Load Balancer is deprecated.	integer	Deprecated Minimum: 0 Maximum: 2147483647 Default: "6"
