Property 'cmd' determines the program to be executed (use a fully qualified name if the program is not on the path). author:    Bela Ban version:    $Id: FD_PING.java,v 1.3.2.1 2007/04/27 08:03:51 belaban Exp $ Inner Class :protected class PingMonitor extends Monitor Inner Class :protected static class Pinger Field Summary  String cmd      Command (script or executable) to ping a host: a return value of 0 means success, anything else is a failure.  boolean verbose      Method Summary protected  Monitor createMonitor()      public  String getName()      public  boolean setProperties(Properties props)      Field Detail cmd String cmd(Code) Command (script or executable) to ping a host: a return value of 0 means success, anything else is a failure.
