Class SessionMonitoringStore

  • @Singleton
public class SessionMonitoringStore
extends Object
    The store for session monitoring information. Each of the operations which can be applied to sessions (refresh, setProperty, destroy and logout) have their own store, which maps the session type (e.g. REMOTE or LOCAL) to the SessionMonitoringTimingStore. This timing store contains a (configurable) number of the most-recent SessionTimingEntry samples, which can be used to calculate e.g. the slowest, or average speed of a given operation. Uses an ExecutorService to perform writes out to the store (which may block).

      • SessionMonitoringStore

        @Inject
public SessionMonitoringStore​(@Named("SESSION_MONITORING_EXECUTOR")
                              ExecutorService executorService,
                              SessionMonitoringTimingStoreFactory sessionMonitoringTimingStoreFactory)
        Guice-powered constructor, setting ourselves up with an executor service (which we will use to offload our monitoring writes). We generate a new synchronized map at construction time ready for monitoring data to be pushed in.
        Parameters:
        executorService - the service to which to offload out writes
