GigaSpaces XAP 9.7.2 API

org.openspaces.admin
Interface Admin

All Superinterfaces:
DumpProvider, StatisticsMonitor

public interface Admin
extends StatisticsMonitor, DumpProvider

The main interface for accessing Admin API. Created using the AdminFactory class.

Provides access to the main elements in the Admin API and in GigaSpaces such as the GridServiceAgents, LookupServices, GridServiceManagers, GridServiceContainers, ProcessingUnits, and Spaces.

Also allows to change monitoring (not statistics) interval (works in a polling fashion) of state changing elements such as the processing unit, the Grid Service Agent, and the Space.

Implements the StatisticsMonitor interface, allowing in one single call (StatisticsMonitor.startStatisticsMonitor()) to start statistics monitors on all the elements it manages (such as the Spaces, and VirtualMachines.

Provides one stop shop for registering all event listeners that extend AdminEventListener using the addEventListener(AdminEventListener) and their removal removeEventListener(AdminEventListener). The actual event listener interfaces will be automatically detected and added to the correct component.

Method Detail

getGroups

String[] getGroups()
Returns the lookup groups this admin uses.

See Also:
AdminFactory.addGroup(String)

getLocators

LookupLocator[] getLocators()
Returns the lookup locators this admin uses.

See Also:
AdminFactory.addLocator(String)

setProcessingUnitMonitorInterval

void setProcessingUnitMonitorInterval(long interval,
                                      TimeUnit timeUnit)
Sets the processing unit monitor (not statistics) interval. The monitor basically checks the status of each processing unit (ProcessingUnit.getStatus() among other things.

Defaults to 1 second.

Parameters:
interval - The interval to use.
timeUnit - The time unit the interval is at.

setAgentProcessessMonitorInterval

void setAgentProcessessMonitorInterval(long interval,
                                       TimeUnit timeUnit)
Sets the Grid Service Agent processes monitor (not statistics) interval. The monitor basically updates the list of processes the agent manages (GridServiceAgent.getProcessesDetails().

Defaults to 5 seconds.

Parameters:
interval - The interval to use.
timeUnit - The time unit the interval is at.

setSpaceMonitorInterval

void setSpaceMonitorInterval(long interval,
                             TimeUnit timeUnit)
Sets the Space monitor (not statistics) interval. The monitor checks each space instance and updates its different status (such as the replication status).

Defaults to 1 second.

Parameters:
interval - The interval to use.
timeUnit - The time unit the interval is at.

setSchedulerCorePoolSize

void setSchedulerCorePoolSize(int coreThreads)
The Admin API uses a shared scheduler thread pool to perform *all* scheduled operations (monitoring, statistics monitoring). The number of threads used can be set here.

Defaults to 10 threads.

Parameters:
coreThreads - The number of threads the shared scheduler thread pool will use,

setDefaultTimeout

void setDefaultTimeout(long timeout,
                       TimeUnit timeUnit)
The default timeout to be used for operations that have a wait for mechanism, i.e. operations with overloaded methods containing (..., long timeout, TimeUnit timeUnit). If not set, the default is Long.MAX_VALUE, TimeUnit.MILLISECONDS

Parameters:
timeout - The timeout value to be used as the default operation timeout if non was provided.
timeUnit - The time-unit corresponding to the timeout.
