Method Detail

getNioActiveThreadCount

@GridMBeanDescription(value="Approximate number of threads that are actively processing NIO tasks.")
int getNioActiveThreadCount()

Returns the approximate number of threads that are actively processing NIO tasks.

Returns:

Approximate number of threads that are actively processing NIO tasks.

getNioTotalCompletedTaskCount

@GridMBeanDescription(value="Approximate total number of NIO tasks that have completed execution.")
long getNioTotalCompletedTaskCount()

Returns the approximate total number of NIO tasks that have completed execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.

Returns:

Approximate total number of NIO tasks that have completed execution.

getNioTaskQueueSize

@GridMBeanDescription(value="Current size of the NIO queue size.")
int getNioTaskQueueSize()

Gets current size of the NIO queue size. NIO queue buffers NIO tasks when there are not threads available for processing in the pool.

Returns:

Current size of the NIO queue size.

getNioCorePoolSize

@GridMBeanDescription(value="Core number of NIO threads.")
int getNioCorePoolSize()

Returns the core number of NIO threads.

Returns:

Core number of NIO threads.

getNioLargestPoolSize

@GridMBeanDescription(value="Largest number of NIO threads that have ever simultaneously been in the pool.")
int getNioLargestPoolSize()

Returns the largest number of NIO threads that have ever simultaneously been in the pool.

Returns:

Largest number of NIO threads that have ever simultaneously been in the pool.

getNioMaximumPoolSize

@GridMBeanDescription(value="Maximum allowed number of NIO threads.")
int getNioMaximumPoolSize()

Returns the maximum allowed number of NIO threads.

Returns:

Maximum allowed number of NIO threads.

getNioPoolSize

@GridMBeanDescription(value="Current number of NIO threads in the pool.")
int getNioPoolSize()

Returns the current number of NIO threads in the pool.

Returns:

Current number of NIO threads in the pool.

getNioTotalScheduledTaskCount

@GridMBeanDescription(value="Approximate total number of NIO tasks that have been scheduled for execution.")
long getNioTotalScheduledTaskCount()

Returns the approximate total number of NIO tasks that have been scheduled for execution. Because the states of tasks and threads may change dynamically during computation, the returned value is only an approximation, but one that does not ever decrease across successive calls.

Returns:

Approximate total number of NIO tasks that have been scheduled for execution.

getLocalAddress

@GridMBeanDescription(value="Grid node IP address.")
String getLocalAddress()

Gets local host address for socket binding. Beside loopback address physical node could have several other ones, but only one is assigned to grid node.

Returns:

Grid node IP address.

getLocalPort

@GridMBeanDescription(value="Port number.")
int getLocalPort()

Gets local port for socket binding.

Returns:

Port number.

getLocalPortRange

@GridMBeanDescription(value="Local port range.")
int getLocalPortRange()

Gets maximum number of local ports tried if all previously tried ports are occupied.

Returns:

Local port range.

getIdleConnectionTimeout

@GridMBeanDescription(value="Maximum idle connection time.")
long getIdleConnectionTimeout()

Gets maximum idle connection time upon which idle connections will be closed.

Returns:

Maximum idle connection time.

isDirectBuffer

@GridMBeanDescription(value="Flag that indicates whether direct or heap allocated buffer is used.")
boolean isDirectBuffer()

Gets flag that indicates whether direct or heap allocated buffer is used.

Returns:

Flag that indicates whether direct or heap allocated buffer is used.

getMessageThreads

@GridMBeanDescription(value="Number of threads used for handling NIO messages.")
int getMessageThreads()

Gets number of threads used for handling NIO messages.

Returns:

Number of threads used for handling NIO messages.
