Method Detail

statistics

JPPFStats statistics()
                     throws Exception

Get the latest statistics snapshot from the JPPF driver.

Returns:

a JPPFStats instance.

Throws:

Exception - if any error occurs.

nodesInformation

Collection<JPPFManagementInfo> nodesInformation()
                                                throws Exception

Request the JMX connection information for all the nodes attached to the server.

Returns:

a collection of NodeManagementInfo instances.

Throws:

Exception - if any error occurs.

restartShutdown

String restartShutdown(Long shutdownDelay,
                       Long restartDelay)
                       throws Exception

Perform a shutdown or restart of the server.

Parameters:

shutdownDelay - the delay before shutting down the server, once the command is received.

restartDelay - the delay before restarting, once the server is shutdown. If it is < 0, no restart occurs.

Returns:

an acknowledgement message.

Throws:

Exception - if any error occurs.

String changeLoadBalancerSettings(String algorithm,
                                  Map<Object,Object> parameters)
                                  throws Exception

Change the bundle size tuning settings.

Parameters:

algorithm - the name opf the load-balancing algorithm to set.

parameters - the algorithm's parameters.

Returns:

an acknowledgement or error message.

Throws:

Exception - if an error occurred while updating the settings.

loadBalancerInformation

LoadBalancingInformation loadBalancerInformation()
                                                 throws Exception

Obtain the current load-balancing settings.

Returns:

an instance of LoadBalancingInformation.

Throws:

Exception - if an error occurred while fetching the settings.

resetStatistics

void resetStatistics()
                     throws Exception

Reset this server's statistics. This method triggers a reset() event via the JPPFDriverStatsManager instance.

Throws:

Exception - if any error occurs.
