Interface AnalysisEngineManagement

All Superinterfaces:
ManagementObject

public interface AnalysisEngineManagement
extends ManagementObject

Monitoring and management interface to an AnalysisEngine. An application can obtain an instance of this object by calling AnalysisEngine.getManagementInterface().

In this implementation, objects implementing this interface will always be JMX-compatible MBeans that you can register with an MBeanServer. For information on JMX see

Method Detail

getName

String getName()
Gets a name for this AnalysisEngineManagement object, which will be unique among all of its siblings (i.e. the objects returned from its parent's getComponents() method.

Returns:
a name for this AnalysisEngineManagement object

getAnalysisTime

long getAnalysisTime()
Gets the total time this AnalysisEngine has spent doing analysis over its entire lifetime. This includes calls to the AnalysisEngine.process(CAS) and AnalysisEngine.processAndOutputNewCASes(CAS) methods, as well as calls to the CasIterator returned from the processAndOutputNewCASes method.

Returns:
the analysis time time in milliseconds

getBatchProcessCompleteTime

long getBatchProcessCompleteTime()
Gets the total time this AnalysisEngine has spent in its batchProcessComplete method over its entire lifetime.

Returns:
the batch process complete time in milliseconds

getCollectionProcessCompleteTime

long getCollectionProcessCompleteTime()
Gets the total time this AnalysisEngine has spent in its collectionProcessComplete method over its entire lifetime.

Returns:
the batch process complete time in milliseconds

getServiceCallTime

long getServiceCallTime()
If this AnalysisEngine is a proxy to a remote service, gets the total time spent making calls on that service.

Returns:
the service call time in milliseconds, or 0 if this AnalysisEngine is not a proxy to a service

getNumberOfCASesProcessed

long getNumberOfCASesProcessed()
Gets the total number of CASes this AnalysisEngine has processed over its lifetime. For a CAS Multipliers, this includes both input and output CASes.

Returns:
the number of CASes processed

getCASesPerSecond

String getCASesPerSecond()
Gets the throughput of this AnalysisEngine, represented as number of CASes processed per second.

Returns:
a string representation of the throughput

getComponents

Map<String,AnalysisEngineManagement> getComponents()
For an Aggregate AnalysisEngine, gets a Map whose values are AnalysisEngineManagement objects that contain the statistics for the components of the aggregate. The keys in the Map are the unique String keys specified in the aggregate AnalysisEngine descriptor. If this AnalysisEngine is a primitive, returns an empty Map.

Returns:
a map from String keys to AnalysisEngineManagement objects

resetStats

void resetStats()
Resets all of the performance statistics to zero. For an Aggregate Analysis Engine, also resets the statistics for all the components of the aggregate.


getState

String getState()
Gets the current state of an AnalysisEngine. The AE should either be in Initializing or Ready state.


getThreadId

long getThreadId()
Gets an id of a thread that was used to initialize AE instance

Returns:
- thread id

getInitializationTime

long getInitializationTime()
Total time it took AnalysisEngine to initialize

Returns:
- initialization time
