ResourceMBean (Lightstreamer JMX MBeans 5.8.1)

```
public interface ResourceMBean
```
One ResourceMBean instance exists in the system, to provide information on the client-originated activity of the Server. It is created at startup by Lightstreamer Server and lasts until the shutdown of the Server.

The main services provided by this MBean are:
- Statistics about the client connections/sockets, also aggregated for type, i.e. http vs https, http vs websocket (like getCurrentWSSockets()).
- Statistics about the connection lifecycle, i.e. connections, TLS handshakes, upgrades to websocket, pending reuse, and disconnections (like getCurrentHandshakingSockets()).
- Statistics about the requests received and the responses sent, also aggregated for type, i.e. streaming vs polling vs control vs page, and for outcome (like getNewControlRequests() and getCumulPollingResponses()).
- Statistics about sessions, also aggregated for their characteristics, i.e. http vs websocket, streaming vs polling (like getCurrentSessionList() and getCurrentWSSessions()).
- Statistics about subscriptions cumulated on all the active sessions (like getTotalSubscribedItems()).
- Statistics about users involved in the active sessions (like getUsernameList()).
- Statistics about "prestarted" sessions, i.e. sessions created but not yet used by the clients (like getMaxPrestartedSessions()).
- Detailed reports on the causes of connection and session closes (like getCumulConnectionCloseCauses(java.lang.String)).
- A destroySession(java.lang.String) operation to enforce the termination of a session.
ResourceMBean name:

  - getTotalSubscribedItems
```
java.lang.Long getTotalSubscribedItems()
```
    Returns:
    
    The total number of currently subscribed Items, covering all the Data Adapters from all the Adapter Sets plugged in the Server. The count includes subscriptions needed to accomplish the Push Notification service.
  - getUsernames

```
    Parameters:
    
    max - The maximum number of elements to be returned, or null if no limit is requested.
    
    Returns:
    
    The list of unique user names of users currently connected to the Server. Expressed as an ArrayList of Strings, where each String contains a user name. Note that null is a possible user name.
    A maximum number of elements to be returned can be set, to protect the client or to get a sample. When the limit is set, the criteria for the determination of the returned elements are left unspecified.
  - getUsernameList
```
java.util.List<java.lang.String> getUsernameList()
```
    Returns:
    
    The list of unique user names of users currently connected to the Server. Expressed as an ArrayList of Strings, where each String contains a user name. Note that null is a possible user name.
    The property is subject to the <disable_long_list_properties> configuration flag. If leveraged, the returned list will just contain a reminder text.

```
    Returns:
    
    The current number of prestarted Sessions. By prestarted Session we mean a session for which no related requests have been received yet. Binding a session with a new connection also brings it out of the prestarted state.

    Note that the concept of failed request is not a strict one; a few main considerations have to be taken into account:
    
    If multiple subrequests of a single Control Request are counted and a severe error occurs in the processing which causes a single error message for the whole Request to be reported to the client, then all subrequests will be considered as failed, regardless of their real outcome.
    
    Streaming and Polling requests are never counted as failed after the data collection phase has started.
    
    Exceptions received from the Data Adapter in subscription and unsubscription operations are not reported to the clients and they are not considered as causing requests to fail.
    
    In case of requests for asynchronous message submission, exceptions received from the Metadata Adapter upon submission are not considered as causing requests to fail.
