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

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

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.
