Method Detail

getRemoteNodeIds

@GridMBeanDescription(value="Set of remote nodes IDs.")
Collection<UUID> getRemoteNodeIds()

Gets set of remote nodes' IDs.

Returns:

Set of remote nodes IDs.

getRemoteNodeCount

@GridMBeanDescription(value="Number of remote nodes.")
int getRemoteNodeCount()

Gets the number of remote nodes.

Returns:

Number of remote nodes.

getConfigurationFile

@GridMBeanDescription(value="Path to JGroups configuration file.")
String getConfigurationFile()

Gets either absolute or relative to GridGain installation home folder path to JGroups XML configuration file.

Returns:

Path to JGroups configuration file.

getLocalHost

@GridMBeanDescription(value="JGroups channel local IP address.")
String getLocalHost()

Gets JGroups channel local IP address.

Returns:

Channel address or null if channel is closed or unconnected.

getLocalPort

@GridMBeanDescription(value="JGroups channel local port number.")
int getLocalPort()

Gets JGroups channel local port number.

Returns:

Channel port or -1 if channel is closed or unconnected.

getJoinTimeout

@GridMBeanDescription(value="Timeout to wait for responses.")
long getJoinTimeout()

Gets time limit in milliseconds to wait for message responses from remote nodes.

Returns:

Timeout to wait for responses.

getGroupName

@GridMBeanDescription(value="JGroups group name.")
String getGroupName()

Gets JGroups group name. In order to communicate with each other nodes must have the same group name.

Returns:

JGroups group name.

getStackName

@GridMBeanDescription(value="JGroups stack name.")
String getStackName()

Gets JGroups stack name. In order to use multiplexor over the same channel SPIs must have the same stack name. Stack name is a name of configuration in the configuration file.

Returns:

JGroups stack name.

getMetricsFrequency

@GridMBeanDescription(value="Delay in milliseconds between metrics requests.")
long getMetricsFrequency()

Gets delay between metrics requests. SPI sends broadcast messages in configurable time interval to another nodes to notify them about node metrics.

Returns:

Time period in milliseconds.
