Instance Attribute Details

#balancing_mode ⇒ String

Specifies the balancing mode for this backend. For global HTTP(S) or TCP/SSL load balancing, the default is UTILIZATION. Valid values are UTILIZATION, RATE (for HTTP(S)) and CONNECTION (for TCP/SSL). For Internal Load Balancing, the default and only supported mode is CONNECTION. Corresponds to the JSON property balancingMode

Returns:

  • (String)

def balancing_mode
  @balancing_mode
end

#capacity_scaler ⇒ Float

A multiplier applied to the group's maximum servicing capacity (based on UTILIZATION, RATE or CONNECTION). Default value is 1, which means the group will serve up to 100% of its configured capacity (depending on balancingMode). A setting of 0 means the group is completely drained, offering 0% of its available Capacity. Valid range is [0.0,1.0]. This cannot be used for internal load balancing. Corresponds to the JSON property capacityScaler

Returns:

  • (Float)

def capacity_scaler
  @capacity_scaler
end

#description ⇒ String

An optional description of this resource. Provide this property when you create the resource. Corresponds to the JSON property description

Returns:

  • (String)

# File 'generated/google/apis/compute_alpha/classes.rb', line 2445

def description
  @description
end

#failover ⇒ Boolean Also known as: failover?

This field designates whether this is a failover backend. More than one failover backend can be configured for a given BackendService. Corresponds to the JSON property failover

Returns:

  • (Boolean)

# File 'generated/google/apis/compute_alpha/classes.rb', line 2451

def failover
  @failover
end

#group ⇒ String

The fully-qualified URL of an Instance Group or Network Endpoint Group resource. In case of instance group this defines the list of instances that serve traffic. Member virtual machine instances from each instance group must live in the same zone as the instance group itself. No two backends in a backend service are allowed to use same Instance Group resource. For Network Endpoint Groups this defines list of endpoints. All endpoints of Network Endpoint Group must be hosted on instances located in the same zone as the Network Endpoint Group. Backend service can not contain mix of Instance Group and Network Endpoint Group backends. Note that you must specify an Instance Group or Network Endpoint Group resource using the fully-qualified URL, rather than a partial URL. When the BackendService has load balancing scheme INTERNAL, the instance group must be within the same region as the BackendService. Network Endpoint Groups are not supported for INTERNAL load balancing scheme. Corresponds to the JSON property group

Returns:

  • (String)

def group
  @group
end

#max_connections ⇒ Fixnum

The max number of simultaneous connections for the group. Can be used with either CONNECTION or UTILIZATION balancing modes. For CONNECTION mode, either maxConnections or maxConnectionsPerInstance must be set. This cannot be used for internal load balancing. Corresponds to the JSON property maxConnections

Returns:

  • (Fixnum)

def max_connections
  @max_connections
end

#max_connections_per_endpoint ⇒ Fixnum

The max number of simultaneous connections that a single backend network endpoint can handle. This is used to calculate the capacity of the group. Can be used in either CONNECTION or UTILIZATION balancing modes. For CONNECTION mode, either maxConnections or maxConnectionsPerEndpoint must be set. This cannot be used for internal load balancing. Corresponds to the JSON property maxConnectionsPerEndpoint

Returns:

  • (Fixnum)

end

#max_connections_per_instance ⇒ Fixnum

The max number of simultaneous connections that a single backend instance can handle. This is used to calculate the capacity of the group. Can be used in either CONNECTION or UTILIZATION balancing modes. For CONNECTION mode, either maxConnections or maxConnectionsPerInstance must be set. This cannot be used for internal load balancing. Corresponds to the JSON property maxConnectionsPerInstance

Returns:

  • (Fixnum)

end

#max_rate ⇒ Fixnum

The max requests per second (RPS) of the group. Can be used with either RATE or UTILIZATION balancing modes, but required if RATE mode. For RATE mode, either maxRate or maxRatePerInstance must be set. This cannot be used for internal load balancing. Corresponds to the JSON property maxRate

Returns:

  • (Fixnum)

end

#max_rate_per_endpoint ⇒ Float

The max requests per second (RPS) that a single backend network endpoint can handle. This is used to calculate the capacity of the group. Can be used in either balancing mode. For RATE mode, either maxRate or maxRatePerEndpoint must be set. This cannot be used for internal load balancing. Corresponds to the JSON property maxRatePerEndpoint

Returns:

  • (Float)

end

#max_rate_per_instance ⇒ Float

The max requests per second (RPS) that a single backend instance can handle. This is used to calculate the capacity of the group. Can be used in either balancing mode. For RATE mode, either maxRate or maxRatePerInstance must be set. This cannot be used for internal load balancing. Corresponds to the JSON property maxRatePerInstance

end

#max_utilization ⇒ Float

Used when balancingMode is UTILIZATION. This ratio defines the CPU utilization target for the group. The default is 0.8. Valid range is [0.0, 1.0]. This cannot be used for internal load balancing. Corresponds to the JSON property maxUtilization

Returns:

  • (Float)
