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.
|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.|
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.
