IWMSServerCurrentCounters Interface

You can use the IWMSServerCurrentCounters interface to retrieve real-time information about the number of connections to the server and the amount of bandwidth allocated to those connections.

In addition to the methods inherited from IDispatch, the IWMSServerCurrentCounters interface exposes the following methods.

Method Description
get_AllCounters Retrieves an array that contains all of the counters supported by the interface.
get_CacheDownloads Retrieves the number of streams being sent to a cache.
get_ConnectedPlayers Retrieves the number of players connected to the server.
get_ConnectionQueue Retrieves the current number of players in the queue to connect to the server.
get_ConnectionRate Retrieves the number of players connecting per second.
get_FileReadRate Retrieves the current bandwidth consumed by file read operations.
get_IncomingBandwidth Retrieves the current bandwidth allocated for incoming connections.
get_LateReadRate Retrieves the number of late read operations per second.
get_LateSendRate Retrieves the number of late send operations per second.
get_OutgoingDistributionAllocatedBandwidth Retrieves the bandwidth that has been allocated for distribution connections.
get_OutgoingDistributionConnections Retrieves the number of server distribution connections.
get_OutgoingDistributionSendRate Retrieves the rate, in Kbps, at which content is being sent to distribution connections.
get_PlayerAllocatedBandwidth Retrieves the bandwidth allocated for player connections.
get_PlayerSendRate Retrieves the rate, in Kbps, at which content is being sent to players.
get_StreamErrorRate Retrieves the number of dropped packets per second.
get_StreamingHTTPPlayers Retrieves the total number of players receiving streamed content using the HTTP protocol.
get_StreamingMMSPlayers Retrieves the total number of players receiving streamed content using the MMS protocol. (The MMS protocol is not supported in Windows Server 2008 operating systems.)
get_StreamingPlayers Retrieves the number of players receiving streamed content.
get_StreamingRTSPPlayers Retrieves the number of players receiving streamed content using the RTSP protocol.
get_StreamingUDPPlayers Retrieves the number of players receiving streamed content using the User Datagram Protocol (UDP).
get_UDPResendRequestsRate Retrieves the number of UDP resend requests per second received by the server.
get_UDPResendsSentRate Retrieves the number of UDP resend requests per second processed by the server.

Example Code

The following example illustrates how to retrieve a pointer to an IWMSServerCurrentCounters interface.

#include <windows.h>
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer                  *pServer;
IWMSServerCurrentCounters   *pCurrentCounters;

HRESULT         hr;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
                      NULL,
                      CLSCTX_ALL,
                      IID_IWMSServer,
                      (void **)&pServer);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to a list of current statistics
// for the server.
hr = pServer->get_CurrentCounters(&pCurrentCounters);
if (FAILED(hr)) goto EXIT;

EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.
