Optimizing the sensitivity threshold

To work at top speed, updates to the weights for the servers are only made if the weights have changed significantly. Constantly updating the weights when there is little or no change in the server status could create unnecessary overhead.

About this task

When the percentage weight change for the total weight for all servers on a port is greater than the sensitivity threshold, the manager updates the weights used by the executor to distribute connections. Consider, for example, that the total weight changes from 100 to 105. The change is 5%. With the default sensitivity threshold of 5, the manager will not update the weights used by the executor, because the percentage change is not above the threshold. If, however, the total weight changes from 100 to 106, the manager will update the weights.
Note: In most cases, you will not need to change this value.

Procedure

To set the manager’s sensitivity threshold to a value other than the default (for example, 6), enter the following command:
dscontrol manager sensitivity 6
