The Bandwidth Policy Service Monitor tool, which is part of the Microsoft Lync Server 2010 Resource Kit, allows administrators visibility into the state of each of the Microsoft Lync Server 2010 communications software Bandwidth Policy services that are defined in the topology. In addition, administrators can see real-time bandwidth usage for all the links that are defined in the Network configuration document. You can download this tool and other Microsoft Lync Server 2010 Resource Kit Tools from the Download Center.

Introduction

The Bandwidth Policy Service Monitor tool is intended to allow administrators to view a list of the following:

1.       All the configured Lync Server 2010 Bandwidth Policy services (Authentication and Core) in the topology

2.       The connections that each service makes to other Bandwidth Policy services and to the Edge servers

3.       All the links that are configured in the Network configuration document and real-time bandwidth usage as reported by each of the Bandwidth Policy services

You can download this tool and other Microsoft Lync Server 2010 Resource Kit Tools from the Download Center.

Description

The Bandwidth Policy Service Monitor tool is implemented as a GUI-based application. Start the tool by running PDPMonUI.exe in the installation directory. The executable takes no command-line arguments.

When the tool starts, it attempts to discover the list of Bandwidth Policy services in the topology. After the initial update is done, the pane to the left of the window has a list of services that are grouped by the clusters they belong to.

When administrators select a particular Bandwidth Policy Service, the pane on the right displays the information about that particular service. That pane also has two main tabs that display information.

Machine Info Tab

The Machine Info tab shows the details of the Bandwidth Policy Service that is selected and the list and state of all the connections that are made by the selected Bandwidth Policy Service to other services.

Topology Info Tab

The Topology Info tab shows a list of all the links that are configured in the Network configuration settings. For each link, the audio and video bandwidth capacity is displayed. Additionally, the currently utilized bandwidth is displayed, both in Kbps and as a percentage of the capacity. The tool uses color-coding to highlight links that have utilization that is close to the capacity-this allows administrators to quickly isolate such links.

Note   If the Bandwidth Policy Service Monitor tool experiences failure when it connects to any of the configured Bandwidth Policy services, the information in the Machine Info and the Topology Info tabs won't be populated. However, it is possible that the tool might connect initially but subsequently lose its connection to the service. In such cases, administrators might see outdated information. There is a Last Updated time stamp on each of the tabs that can allow administrators to see when the data was last updated for a particular Bandwidth Policy Service.

Output

There is no command-line output; the program output is contained within the main GUI.

Purpose

The purpose of the Bandwidth Policy Service Monitor tool is to allow administrators visibility into the state of each of the Bandwidth Policy services that are defined in the topology. In addition, administrators can see real-time bandwidth usage for all the links that are defined in the Network configuration document. For more information, see the "Description" section of this article.

Requirements

The Bandwidth Policy Service Monitor tool needs to be run on a computer that is part of the Lync Server topology.

Summary

The Bandwidth Policy Service Monitor tool can be a valuable resource to administrators so they can inspect the state of all the Bandwidth Policy services in the topology-and more importantly-they can obtain real-time bandwidth utilization for the links that are defined in the Network configuration settings.

  • Hi there,

    I work for a government organization and we are stuck under an old contract that really limits our bandwidth provided.  We currently have OCS 2007 R2 in production but using Live Meeting 2007 has been a tough sell because the client experience has been mixed due to the bandwidth contraints.  Upper management has instructed us to take a look at the newer Lync 2010 release and see if upgrading can provide us with a better tool set and allow us to have greater bandwidth controls from our own servers.  Is there a way in Lync 2010 to control stuff like the amount of conferences that can happen at any given time?  We have been using a Sharepoint calendar that people check against to see if there are any other meetings already scheduled or in progress but it is just an honor system and if a bunch of users have one off conferences of their own it really degrades the quality for all others.  

    Thanks,

    Doug
