Response Time

The Response Time Dispatch Method enables LinkProof to select the fastest server in the farm. When this method is specified, the load-balancing process is based on choosing the least loaded server as calculated by the Response Level as measured by the Health Monitoring module. The Health Monitoring module enables you to track the round trip time of health checks. The device keeps a Response Level indicator for each check. The Response Level is the average ratio between the actual response time and the configured timeout. This average is calculated over a number of samples as defined in the Response Level Samples parameter. A value of 0 in the Response Level Samples parameter disables the parameter. Any other value, from 1 through 9 defines the samples number. The Response Level Samples parameter can be used in the health checks in which the Measure Response Time parameter is enabled.

Configuration of the Response Time Dispatch Method involves the following steps:

Setting health checks for servers in the farm. When you configure the health-check parameters, enable the Measure Response Time option for each health check.

Enabling the Health Monitoring module for this farm (see Health Monitoring).

Setting the Dispatch Method parameter in the farm to Response Time.

Setting the Response Level Samples parameter.
