ping

public void ping(InetAddress host,
                 long timeout,
                 int retries,
                 int sequenceId,
                 PingResponseCallback cb)
          throws Exception

ping

Specified by:

ping in interface Pinger

Parameters:

host - a InetAddress object.

timeout - a long.

retries - a int.

sequenceId - a short.

cb - a org.opennms.netmgt.ping.PingResponseCallback object.

Throws:

Exception - if any.

ping

public Number ping(InetAddress host,
                   long timeout,
                   int retries)
            throws Exception

This method is used to ping a remote host to test for ICMP support. If the remote host responds within the specified period, defined by retries and timeouts, then the response time is returned.

Specified by:

ping in interface Pinger

Parameters:

host - The address to poll.

timeout - The time to wait between each retry.

retries - The number of times to retry

Returns:

The response time in microseconds if the host is reachable and has responded with an echo reply, otherwise a null value.

Throws:

InterruptedException - if any.

IOException - if any.

Exception - if any.

ping

public Number ping(InetAddress host)
            throws Exception

Ping a remote host, using the default number of retries and timeouts.

Specified by:

ping in interface Pinger

Parameters:

host - the host to ping

Returns:

the round-trip time of the packet

Throws:

IOException - if any.

InterruptedException - if any.

Exception - if any.

                                 long pingInterval)
                          throws Exception

parallelPing

Specified by:

parallelPing in interface Pinger

Parameters:

host - a InetAddress object.

count - a int.

timeout - a long.

pingInterval - a long.

Returns:

a List object.

Throws:

Exception - if any.
