WildFly 35 Model Reference

Built-in load metric contributing a value to the overall load factor of a node. The load factors from each metric are aggregated according to their weights.

Attributes (5)

  • capacity Maximum capacity of the metric used to normalize the load values from a metric which require explicit capacity.
    • Attribute Value
    Default Value 1.0
    Type DOUBLE
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • class Class name to use to construct a load metric from.
    • Attribute Value
    Type STRING
    Nillable false
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • module Module name from which to load the load metric class.
    • Attribute Value
    Default Value org.wildfly.extension.mod_cluster
    Type STRING
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • property Properties to apply on a loaded metric instance.
    • Attribute Value
    Type OBJECT
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default
  • weight Number indicating the significance of a metric with respect to the other metrics. For example, a metric of weight 2 will have twice the impact on the overall load factor than a metric of weight 1.
    • Attribute Value
    Default Value 1
    Type INT
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
    Stability default

Operations (2)

  • add Add a load metric to the set of load metrics to calculate the load factor from.
    Request Parameter Type Required Expressions Allowed Default value Description
    capacity DOUBLE false true 1.0 Maximum capacity of the metric used to normalize the load values from a metric which require explicit capacity.
    class STRING true true Class name to use to construct a load metric from.
    module STRING false true org.wildfly.extension.mod_cluster Module name from which to load the load metric class.
    property OBJECT false true Properties to apply on a loaded metric instance.
    weight INT false true 1 Number indicating the significance of a metric with respect to the other metrics. For example, a metric of weight 2 will have twice the impact on the overall load factor than a metric of weight 1.
  • remove Remove a load metric from the set of load metrics to calculate the load factor from.
