This section is used to configure the measurement of Java VM breaks. Prolonged VM breaks (“hiccups”) of this nature are not desirable. They can be caused by a lengthy GarbageCollection, for example. The MBean HiccupMeter used to measure brakes uses a dedicated thread which can be started and stopped.

hiccup.startThread

This thread is used to start the metering thread (default value: true).

hiccup.warningLogLimit

This parameter is used to configure a time interval in seconds (default value 20 s). A warning is written to the server log when the time interval expires for a Java VM break.
