1.2.13.Final, 1.3.7.Final
Description
In chapter 10 (http://docs.jboss.org/mod_cluster/1.3.0/html_single/#java.load), it says:
The DynamicLoadBalanceFactorProvider applies a time decay function to the loads returned by each metric. The aggregate load, with respect to previous load values, can be expressed by the following formula:
L = (L 0 + L 1/D + L 2/D 2 + L 3/D 3 + ... + L H/D H) * (1 + D + D 2 + D 3 + ... D H)
... or more concisely as:
L = (∑Hi=0 L i/D i) * (∑Hi=0 D i)
... where D = decayFactor, and H = history.
But both formulas are wrong.
It should says:
The DynamicLoadBalanceFactorProvider applies a time decay function to the loads returned by each metric. The aggregate load, with respect to previous load values, can be expressed by the following formula:
L = (L 0/D 0 + L 1/D 1 + L 2/D 2 + L 3/D 3 + ... + L H/D H) / (1/D 0 + 1/D 1 + 1/D 2 + 1/D 3 + ... 1/D H)
... or more concisely as:
L = (∑Hi=0 L i/D i) / (∑Hi=0 1/ D i)
... where D = decayFactor, and H = history.
