Constructor Detail

### ApplicationViewStatistics

    public ApplicationViewStatistics(String id)

### ApplicationViewStatistics

    public ApplicationViewStatistics(String id,
                                     Iterator eventNames,
                                     Iterator serviceNames)

Method Detail

### combine

    public void combine(ApplicationViewStatistics stats)

  Aggregate the given statistics with this statistics object. The details of the aggregation for each field depends on the type of statistic the field represents. Fields representing absolute counts are simply summed. Fields representing averages are averaged together.

  Parameters:
    `stats` -

### getID

    public String getID()

  Get the ID of the ApplicationView these statistics represent.

  Returns:

### getEventStatistics

    public EventStatistics getEventStatistics(String eventName,
                                              boolean forUpdate)

  Get an EventStatistics instance representing stats for the event given by eventName, or aggregate stats across all events for this AppView if eventName is null.

### getServiceStatistics

    public ServiceStatistics getServiceStatistics(String serviceName,
                                                  boolean forUpdate)

  Get a ServiceStatistics instance representing stats for the service given by serviceName, or aggregate stats across all services for this AppView if serviceName is null.

### resetEventCounts

    public void resetEventCounts()

  Reset all raw event counters to 0 (this does not include suspended event count), and note the time at which the counts were reset.

### resetServiceCounts

    public void resetServiceCounts()

  Reset all raw service counters to 0 (this does not include suspended service count), and note the time at which the counts were reset.

### getLastEventCountResetTime

    public long getLastEventCountResetTime()

  Get the last time at which event counts were reset.

  Returns:

### getLastServiceCountResetTime

    public long getLastServiceCountResetTime()

  Get the last time at which service counts were reset.

  Returns:

### resetSuspendedAsyncServiceCounts

    public void resetSuspendedAsyncServiceCounts()

  Reset the suspended async service count for all services on this AppView to zero. This method should only be used when it is known that there are no suspended async services, and the current count is incorrect due to transaction rollbacks in the async service processor.

### getLastEventDeliveryTime

    public long getLastEventDeliveryTime()

  Get the last time at which an event was delivered for this AppView.

  Returns:

### getLastServiceInvocationTime

    public long getLastServiceInvocationTime()

  Get the last time at which a service was invoked on this AppView.

  Returns:

### getAverageAsyncServiceWaitTime

    public long getAverageAsyncServiceWaitTime()

  Get the average number of milliseconds async service requests wait on the async service request queue before being processed.

  Returns:

### addAsyncServiceWaitTime

    public void addAsyncServiceWaitTime(long time)

  Add a individual wait time (in milliseconds) for a single request that was just processed off the async service request queue.

  Parameters:
    `time` -
