Monitoring Lync with the User Registrations Viewer—Free NMC tool #2

By Mark Pinskey

Sr. Product Marketing Manager – Automated Network Management

 

Editor's note: HP Software recently announced the launch of six free network utilities. This series of blog posts provides short overviews of how each tool can help you manage your network.

 

Microsoft Lync Unified Communications (UC) deployments on corporate networks require close monitoring. Administrators or operators who are managing Lync need quick access to information about configured Lync users, and the ability to check dynamic information about the users such as their registration and their Front End pool or server in order to track the changing distribution of user registrations.

 

HP User Registrations Viewer for Microsoft Lync, a new free Network Management Center tool, gives administrators a clear view of activity across the Lync central site and associated branch sites. The Viewer provides insight into configuration settings of individual Lync users, and offers a quick way to compare the actual distributions of user registrations versus the planned capacity for the load balanced pools of Front End servers.

 

What it does

The Viewer has two main tabs, Configured Lync Users and Registered Lync Users.

 

Configured Lync Users (Figure 1) provides an inventory of all users, including information on primary registrar, voice and location policies and dial plans assigned to the user. This tab also includes a dashboard that illustrates the number of total configured users vs. unique registered users, which lets an administrator gauge overall Lync license and infrastructure usage and adjust capacity and licenses accordingly.

The second tab, Registered Lync Users (Figure 2), provides an inventory of all users who are currently signed in and using the Lync infrastructure. This inventory contains information such as the client version, IP address and the physical Front End server that the user is signed in to.

 

This tab also features a dashboard that illustrates:

○      Registrations by Front End pool

○      Registrations by Front End servers

○      Registrations by client applications and versions

○      Registrations by login type (Internal / External, ex. coming in via an Edge Server)

Working with the tool

Once installed using a standard Microsoft Installer, the tool can be launched via the desktop or the Programs menu shortcuts.

 

When the user clicks on refresh, the tool uses a combination of Powershell and SQL to retrieve information about configured and registered users from all Front End pools of the central site that the selected Front End pool belongs to, and additionally from all the Front End Pools in Branch sites associated with the central site.

 

For the tool to be able to communicate with the Lync server and retrieve all the required information, the user must configure the following using the Communication Configuration page (Figure 3), found in the Options menu:

 

  • FQDN of one Front End pool per Central Site — Although a single Lync server deployment or Lync site could have multiple central site Front End servers pools configured for user registrations, and Lync server deployment could also have associated branch sites and corresponding branch Front End server pools, the tool needs the FQDN of just one of the multiple central site Front End Server Pools.
  • Credentials of a user belonging to the RTCUniversalServerAdmins group of Windows users configured for Lync — User of the tool must be a domain user belonging to the RTCUniversalServerAdmins group, which must also be enabled to login to the RTCLOCAL database instance of each Lync Front End server with a specific set of permissions.

Once configured, the Front End pools display in the drop down menu on the Configured Lync Users tab (Figure 4).

Please note that there is no support for authentication and authorization of tool users. However, tool users must specify one of the Front End Server Pool’s FQDN and associated windows authentication credentials for the tool to be able to retrieve information about configured Lync users and their registrations.
