LBPool

Defining access of a Group from a LBVirtualServer and binding to LBMonitorProfile.


Properties

Required Property Name Type Description
optional _create_time integer

Timestamp of resource creation

optional _create_user string

ID of the user who created this resource

optional _last_modified_time integer

Timestamp of last modification

optional _last_modified_user string

ID of the user who last modified this resource

optional _links array of ResourceLink

The server will populate this field when returing the resource. Ignored on PUT and POST.

optional _protection string

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.

optional _revision integer

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.

optional _schema string

Schema for this resource

optional _self SelfResourceLink

Link to this resource

optional _system_owned boolean

Indicates system owned resource

optional active_monitor_paths array of string

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. Currently, only one active health monitor can be configured per server pool.

optional algorithm string

Load Balancing algorithm chooses a server for each new connection by going through the list of servers in the pool. Currently, following load balancing algorithms are supported with ROUND_ROBIN as the default. ROUND_ROBIN means that a server is selected in a round-robin fashion. The weight would be ignored even if it is configured. WEIGHTED_ROUND_ROBIN means that a server is selected in a weighted round-robin fashion. Default weight of 1 is used if weight is not configured. LEAST_CONNECTION means that a server is selected when it has the least number of connections. The weight would be ignored even if it is configured. Slow start would be enabled by default. WEIGHTED_LEAST_CONNECTION means that a server is selected in a weighted least connection fashion. Default weight of 1 is used if weight is not configured. Slow start would be enabled by default. IP_HASH means that consistent hash is performed on the source IP address of the incoming connection. This ensures that the same client IP address will always reach the same server as long as no server goes down or up. It may be used on the Internet to provide a best-effort stickiness to clients which refuse session cookies.

optional children array of ChildPolicyConfigResource

subtree for this type within policy tree containing nested elements.

optional description string

Description of this resource

optional display_name string

Defaults to ID if not set

optional id string

Unique identifier of this resource

optional marked_for_delete boolean

Intent objects are not directly deleted from the system when a delete is invoked on them. They are marked for deletion and only when all the realized entities for that intent object gets deleted, the intent object is deleted. Objects that are marked for deletion are not returned in GET call. One can use the search API to get these objects.

optional member_group LBPoolMemberGroup

Load balancer pool support grouping object as dynamic pool members. When member group is defined, members setting should not be specified.

optional members array of LBPoolMember

Server pool consists of one or more pool members. Each pool member is identified, typically, by an IP address and a port.

optional min_active_members integer

A pool is considered active if there are at least certain minimum number of members.

optional parent_path string

Path of its parent

optional passive_monitor_path string

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.

optional path string

Absolute path of this object

optional relative_path string

Path relative from its parent

optional resource_type string

The type of this resource.

optional snat_translation LBSnatTranslation

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. By default Source NAT is enabled as LBSnatAutoMap.

optional tags array of Tag

Opaque identifiers meaningful to the API user

optional tcp_multiplexing_enabled boolean

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.

optional tcp_multiplexing_number integer

The maximum number of TCP connections per pool that are idly kept alive for sending future client requests.
