Class JniNetStat

java.lang.Object
  com.caucho.server.admin.JniNetStat

All Implemented Interfaces:

AlarmListener, java.util.EventListener

public class JniNetStat
extends java.lang.Object
implements AlarmListener

Statistics gathering attribute. Each time period, the attribute is polled. Samples the network every _samplePeriod seconds. Because the netstat sample can be slow, it has its own thread independent of the standard stat sample.
