To configure and enable multicast logging
- In the console tree, click the broadcast publishing point you want to log multicast information for. If it is started, stop the publishing point.
- In the details pane, click the Properties tab.
- In Category, click Multicast streaming.
- In Plug-in, click WMS Multicast Data Writer, and then click Properties.
- WMS Multicast Data Writer Properties appears.
- In the Windows Media Services snap-in, click the Advanced tab.
- Configure the following setting:
- Logging URL. Type the URL of the Wmsiislog.dll file on your Web server, such as http://web_server_name/virtual_directory /wmsiislog.dll.
- Click OK to apply the new setting to the plug-in.
- In the details pane, on the Properties tab, in Category, click Multicast streaming, iIn Plug-in, click the WMS Multicast Data Writer plug-in, and then click the Enable button.
- Run the Multicast Announcement Wizard to create a new multicast information file (.nsc file) for your multicast.
Notes
- This procedure requires that your Web server running Internet Information Services (IIS) has a virtual directory that references the %systemdrive%\Wmpub\Wmiislog\ directory and that the Wmsiislog.dll has been granted executable permissions on the virtual root. For more information about using executable ISAPI filters and Web service extensions, see Internet Information Services Help.
- If you want to change the log file recycling period, you can change the setting in Internet Information Services (IIS). For more information about log file settings, see IIS Help.
- A client sends logging information to the IIS server after the client stops streaming a multicast. After the server receives logging information from a client, it may take several minutes before that information is added to the log file.
- If you change the settings of the WMS Multicast Data Writer plug-in, you must create a new multicast information file for clients to be able to receive to the multicast stream. You can create the multicast information file by using the Multicast Announcement Wizard available in the Windows Media Services snap-in.
- Windows Media Services does not include a logging plug-in that works with encoder push scenarios. You can log encoder push broadcast data by creating an active script logging plug-in. For more information about creating a custom plug-in, see the Windows Media Services Software Development Kit (SDK), which can be downloaded from the Windows Media home page at the Microsoft Web site.
- The default location of the multicast log files created by the Multicast and Advertisement Logging Agent is %systemroot%\System32\Logfiles\WMS_ISAPI. The log file name is WMS_yyyymmdd.log, where yyyymmdd is the year, month, and day when the log file is created. If more than one log file is generated in a day, an incremented number is added to the file name, using the format WMS_yyyymmdd_iiii.log. For example, if the first log is named WMS_20040304.log, the second log on that day is named WMS_20040304_0001.log, and so forth.
- The server does not use your user account to access folders and other resources; it uses the Network Service account by default. If you are writing log files to a location other than C:\WMPub and its subdirectories, make sure that the folder is shared and that the Network Service account has read and write permissions for the folder. If the Network Service account does not have permissions for a folder, the server will not be able to write log files to it. For more information about rights and permissions, see Understanding rights.
- Multicast streaming and the WMS Multicast Data Writer plug-in are available only if Windows Media Services 9 Series is running on the following editions of the operating system: Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter Edition. If you are running Windows Server 2003, Standard Edition, these features are not supported.
