java.lang.Objectorg.opennms.netmgt.poller.monitors.IPv4LatencyMonitor
org.opennms.netmgt.poller.monitors.IcmpMonitor
This class is designed to be used by the service poller framework to test the availability of the ICMP service on remote interfaces. The class implements the ServiceMonitor interface that allows it to be used along with other plug-ins by the service poller framework.

public int poll(NetworkInterface iface, java.util.Map parameters, Package pkg)
Poll the specified address for ICMP service availability.
The ICMP service monitor relies on Discovery for the actual generation of IMCP 'ping' requests. A JSDT session with two channels (send/recv) is utilized for passing poll requests and receiving poll replies from discovery. All exchanges are SOAP/XML compliant.
iface
- The network interface to test the service on.parameters
- The package parameters (timeout, retry, etc...) to be used for
this poll.
