Examples of com.sun.sgs.impl.service.watchdog.WatchdogServiceImpl

com.sun.sgs.impl.service.watchdog.WatchdogServiceImpl
The {@link WatchdogService} implementation.
The {@link #WatchdogServiceImpl constructor} supports the followingproperties:

Property: com.sun.sgs.impl.service.watchdog.server.host
Default: the value of the {@code com.sun.sgs.server.host}property, if present, or {@code localhost} if this node is starting the server

Specifies the host name for the watchdog server that this service contacts. If the {@code com.sun.sgs.node.type} property is not {@code appNode}, then this property's default is used (since the watchdog server to contact will be the one started on the local host).
Property: com.sun.sgs.impl.service.watchdog.server.port
Default: {@code 44533}
Specifies the network port for the watchdog server that this service contacts (and, optionally, starts). If the {@code com.sun.sgs.node.type} property is not {@code singleNode}, then the value must be greater than or equal to {@code 0} and no greater than {@code 65535}, otherwise the value must be greater than {@code 0}, and no greater than {@code 65535}.

Property: com.sun.sgs.impl.service.watchdog.client.host
Default: the local host name

Specifies the host name for the watchdog client used when registering the node with the watchdog service.
Property: com.sun.sgs.impl.service.watchdog.client.port
Default: {@code 0} (anonymous port)
Specifies the network port for this watchdog service for receiving node status change notifications from the watchdog server. The value must be greater than or equal to {@code 0} and no greater than{@code 65535}.

Property: com.sun.management.jmxremote.port
Default: None

Enables remote JMX monitoring through the specified port. By default, remote monitoring is not enabled. Not that this is a system property, and must be set on the command line when starting the node.
