Configuration and runtime operations for mod_cluster subsystem.

Children (2)

  • custom-load-metric Custom load metric loaded from a specified Java class contributing a value to the overall load factor of a node. The load factors from each metric are aggregated according to their weights.
  • load-metric 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 (3)

  • decay The factor by which a historic load values should degrade in significance.
    • Attribute Value
    Default Value 2.0
    Type DOUBLE
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
  • history The number of historic (previous) load values to consider in the load balance factor computation.
    • Attribute Value
    Default Value 9
    Type INT
    Nillable true
    Expressions Allowed true
    Storage configuration
    Access Type read-write
    Restart Required all-services
  • initial-load Initial load within the range [0..100] with which to prepopulate historical values. Used to gradually drive load to the node. Value of 0 prepopulates with full load and value of -1 disables this behavior.
    • Attribute Value
    Default Value 0
    Type INT
    Nillable true
    Expressions Allowed true
    Min -1
    Max 100
    Storage configuration
    Access Type read-write
    Restart Required all-services

Operations (2)

  • add Add a dynamic load provider with no load metrics.
    Request Parameter Type Required Expressions Allowed Default value Description
    decay DOUBLE false true 2.0 The factor by which a historic load values should degrade in significance.
    history INT false true 9 The number of historic (previous) load values to consider in the load balance factor computation.
    initial-load INT false true 0 Initial load within the range [0..100] with which to prepopulate historical values. Used to gradually drive load to the node. Value of 0 prepopulates with full load and value of -1 disables this behavior.
  • remove Remove a dynamic load provider defaulting to simple load provider.
