Class ThrottleStateUpdaterThread

java.lang.Object

org.graylog2.plugin.periodical.Periodical

org.graylog2.periodical.ThrottleStateUpdaterThread

All Implemented Interfaces:

Runnable

public class ThrottleStateUpdaterThread
extends Periodical

The ThrottleStateUpdater publishes the current state buffer state of the journal to other interested parties, chiefly the ThrottleableTransports.

It only includes the necessary information to make a decision about whether to throttle parts of the system, but does not send "throttle" commands. This allows for a flexible approach in picking a throttling strategy.

The implementation expects to be called once per second to have a rough estimate about the events per second, over the last second.
