IWMSPublishingPointTotalCounters Interface

  • Articolo

You can use the IWMSPublishingPointTotalCounters interface to retrieve totals for the number of connections to the server and the amount of bandwidth allocated to the connections.

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

Method

Description

get_Advertisements

Retrieves the cumulative number of advertisements that have been streamed from playlists since the last reset.

get_AllCounters

Retrieves an array that contains all of the counters supported by the interface.

get_ConnectedPlayers

Retrieves the total number of players connected to the publishing point since the last reset.

get_CountersStartTime

Retrieves the date and time at which the publishing point started monitoring the total counters.

get_FileBytesRead

Retrieves the total number of bytes read from the publishing point since the last reset.

get_LateReads

Retrieves the total number of read operations that took over 400 milliseconds.

get_OutgoingDistributionBytesSent

Retrieves the total number of bytes sent to distribution connections since the last reset.

get_OutgoingDistributionConnections

Retrieves the total number of distribution connections established since the last reset.

get_PlayerBytesSent

Retrieves the total number of bytes sent to players since the last reset.

get_StreamDenials

Retrieves the total number of stream transmissions denied since the last reset.

get_StreamErrors

Retrieves the total number of dropped-packet errors since the last reset.

get_StreamingPlayers

Retrieves the total number of players that have streamed data from the publishing point since the last reset.

get_StreamingHTTPPlayers

Retrieves the total number of players that have streamed data by using the HTTP protocol from the publishing point since the last reset.

get_StreamingRTSPPlayers

Retrieves the total number of players that have streamed data by using the RTSP protocol from the publishing point since the last reset.

get_StreamingUDPPlayers

Retrieves the total number of players that have streamed data by using the User Datagram Protocol (UDP) from the publishing point since the last reset.

get_StreamTerminations

Retrieves the total number of stream transmissions that have been terminated since the last reset.

Reset

Resets the counters to the current values.

Example

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

#include <windows.h>
#include <atlbase.h>    // Includes CComVariant.
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer                          *pServer;
IWMSPublishingPoints                *pPubPoints;
IWMSPublishingPoint                 *pPubPoint;
IWMSPublishingPointTotalCounters    *pTotalCounters;

HRESULT         hr;
CComVariant     varIndex;
long            lCount;

// 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 the IWMSPublishingPoints interface
// and retrieve the total count of publishing points.
hr = pServer->get_PublishingPoints(&pPubPoints);
if (FAILED(hr)) goto EXIT;
hr = pPubPoints->get_Count(&lCount);
if (FAILED(hr)) goto EXIT;

// Retrieve information about each publishing point.
for (long x = 0; x < lCount; x++)
{
    varIndex = x;
    hr = pPubPoints->get_Item(varIndex, &pPubPoint);
    if (FAILED(hr)) goto EXIT;

    // Retrieve a pointer to a list of total statistics
    // for the publishing point.
    hr = pPubPoint->get_TotalCounters(&pTotalCounters);
    if (FAILED(hr)) goto EXIT;

    // Release temporary COM objects.
    pPubPoint->Release();
    pTotalCounters->Release();
}

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