Optimizing the manager interval

To optimize overall performance, the manager is restricted in how often it can interact with the executor. You can make changes to this interval by entering the dscontrol manager interval and dscontrol manager refresh commands.

About this task

The manager interval specifies how often the manager will update the server weights that the executor uses in routing connections. If the manager interval is too low, it can mean poor performance as a result of the manager constantly interrupting the executor. If the manager interval is too high, it can mean that the executor’s request routing will not be based on accurate, up-to-date information.

The manager refresh cycle specifies how often the manager will ask the executor for status information. The refresh cycle is based on the interval time.

Procedure

  1. Set the manager interval time, in seconds. For example, to set the manager interval to 1 second, enter the following command:
    dscontrol manager interval 1
  2. Set the manager refresh time, in seconds. For example, to set the manager refresh cycle to 3, enter the following command:
    dscontrol manager refresh 3 
    This will cause the manager to wait for 3 intervals before asking the executor for status.
