Summary: Install and configure watcher nodes for 비즈니스용 Skype 서버 synthetic transactions.

Watcher nodes are computers that periodically run 비즈니스용 Skype 서버 synthetic transactions. Synthetic transactions are Windows PowerShell cmdlets that verify that key user scenarios, such as the ability to sign in or to exchange instant messages, are working as expected. For 비즈니스용 Skype 서버 2015, System Center Operations Manager can run the synthetic transactions shown in the following table, which includes three synthetic transaction types:

  • Default   Synthetic transactions that a watcher node runs by default. When you create a new watcher node, you can specify which synthetic transactions that node will run. (That's the purpose of the Tests parameter used by the New-CsWatcherNodeConfiguration cmdlet.) If you do not use the Tests parameter when the watcher node is created, it will automatically run all the Default synthetic transactions and will not run any of the Non-default synthetic transactions. This means, for example, that the watcher node will be configured to run the Test-CsAddressBookService test, but will not be configured to run the Test-CsExumConnectivity test.

  • Non-default   Tests that watcher nodes do not run by default. (For details, see the description of the Default type.) However, the watcher node can be enabled to run any of the Non-default synthetic transactions. You can do this when you create the watcher node (by using the New-CsWatcherNodeConfiguration cmdlet), or any time after the watcher node has been created. Note that many of the Non-default synthetic transactions require extra setup steps. For details about these steps, see Special Setup Instructions for Synthetic Transactions. For more details about these steps, see Special Setup Instructions for Synthetic Transactions.

  • Extended   A special type of Non-default synthetic transaction. Unlike other synthetic transactions, Extended tests can be run multiple times during each pass. This is useful when verifying behavior, such as multiple public switched telephone network (PSTN) voice routes for a pool. You can configure this simply by adding multiple instances of an extended test to a watcher node.

For details about the process for adding other synthetic transactions to a watcher node, see Configure a Watcher Node to Run Synthetic Transactions. You can also use 비즈니스용 Skype 서버 관리 쉘 to remove synthetic transactions from a watcher node.

The synthetic transactions available to watcher nodes include the following:

You do not need to install watcher nodes to use System Center Operations Manager. If you do not install these nodes, you can still get real-time alerts from 비즈니스용 Skype 서버 2015 components whenever an issue occurs. (The Component and User Management Pack does not use watcher nodes.) However, watcher nodes are required if you want to monitor end-to-end scenarios by using the Active Monitoring Management pack.

note참고:
Administrators can also run synthetic transactions manually, without using or installing Operations Manager. Depending on the size of your 비즈니스용 Skype 서버 deployment, synthetic transactions can use a large amount of computer memory and processor time. Because of this, we recommend that you use a dedicated computer as a watcher node. For example, you should not configure a 비즈니스용 Skype 서버 프런트 엔드 서버 to act as a watcher node. Watcher nodes should meet the same basic hardware requirements as any other computer in your 비즈니스용 Skype 서버 topology.
note참고:
A legacy Lync Server 2013 watcher node cannot be collocated on the same machine as a 비즈니스용 Skype 서버 2015 watcher node because the core system files for Lync Server 2013 and 비즈니스용 Skype 서버 2015 cannot be installed on the same computer. However, 비즈니스용 Skype 서버 2015 watcher nodes can simultaneously monitor 비즈니스용 Skype 서버 2015 and Lync Server 2013. Default synthetic transactions are supported for both product versions.

Lync Server 2013 watcher nodes may be deployed inside or outside an enterprise to help verify:

  • Connectivity to pools for users inside the enterprise.

  • Connectivity through perimeter networks for remote users working outside the enterprise.

  • Connectivity to branch office appliances.

  • Connectivity to Lync Server 2013 inside the enterprise and through perimeter networks.

To help simplify administration, different authentication options are available for inside and outside of the enterprise. For details, see Configure a Watcher Node to Run Synthetic Transactions.

To configure a computer to act as a watcher node, you must first complete the following prerequisites:

  • Install System Center Operations Manager and import the 비즈니스용 Skype 서버 2015 management packs. You must also first verify that the watcher node computer meets all prerequisites for installing 비즈니스용 Skype 서버 2015.

  • Install the following items on the watcher node computer:

    • The full version of .NET Framework 4.5

    • Windows Identity Foundation

    • Windows PowerShell 3.0

After the prerequisites are met, you can configure the watcher node by following these steps:

  1. Install the 비즈니스용 Skype 서버 2015 core files on the watcher node computer.

  2. Install System Center Operations Manager agent on the watcher node computer.

  3. Run the Watchernode.msi executable file.

  4. Use the New-CsWatcherNodeConfiguration cmdlet to configure test user accounts to be employed by the watcher node.

To install the 비즈니스용 Skype 서버 2015 core files on a computer, complete the following procedure. The RTCLocal database will automatically be installed when you install the core files. Note that you do not need to install SQL Server on the watcher nodes. SQL Server Express will be automatically installed.

To install the 비즈니스용 Skype 서버 2015 core files and the RTCLocal database:

  1. On the watcher node computer, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  2. In the console window, type the following command and press ENTER. Be sure to enter the appropriate path to your 비즈니스용 Skype 서버 setup files:

    D:\Setup.exe /BootstrapLocalMgmt

To verify that the core 비즈니스용 Skype 서버 components are successfully installed, click Start, click All Programs, click 비즈니스용 Skype 서버 2015, and then click 비즈니스용 Skype 서버 관리 쉘. In the 비즈니스용 Skype 서버 관리 쉘, type the following Windows PowerShell command and press ENTER:

Get-CsWatcherNodeConfiguration
note참고:
The first time you run this command, no data will be returned because you have not yet configured any watcher node computers. If the command runs without returning an error, you can assume that the 비즈니스용 Skype 서버 setup completed successfully.

If your watcher node computer is located inside your perimeter network, you can run the following command to verify the installation of Skype for Business Server 2015:

Get-CsPinPolicy

You will receive information similar to this, depending on the number of PIN policies configured for use in your organization:

Identity : Global

Description :

MinPasswordLength : 5

PINHistoryCount : 0

AllowCommonPatterns : False

PINLifetime : 0

MaximumLogonAttempts :

If you see information about your PIN policies, the core components have been successfully installed.

Similar to 비즈니스용 Skype 서버 setup for reporting component alerts, a 비즈니스용 Skype 서버 2015 watcher node requires System Center Operations Manager agent files to be installed. This enables the synthetic transactions to be run and alerts to be reported to the System Center Operations Manager Root Management Server.

To install the agent files, follow the procedures listed in Configure the Skype for Business Server computers that will be monitored.

After the System Center Operations Manager agent files have been installed, you must configure the watcher node itself. The steps you take to do this will vary, depending on whether your watcher node computer is inside your perimeter network or outside your perimeter network.

When you configure a watcher node, you must also choose the type of authentication method to be employed by that node. 비즈니스용 Skype 서버 2015 enables you to choose one of two authentication methods: Trusted Server or Credential Authentication. The following table shows the differences between these two methods:

 

 DescriptionLocations supported

TrustedServer

Uses a certificate to impersonate an internal server and bypass authentication challenges.

Useful for administrators who prefer to manage a single certificate, instead of many user passwords on each watcher node.

Inside the enterprise.

With this method, the watcher node must be in the same domain as the pools being monitored. If the watcher node and the pools are in different domains, use Credential Authentication instead.

Negotiate

Stores user names and passwords securely in Windows Credential Manager on each watcher node.

This mode requires more password management, but is the only option for watcher nodes outside the enterprise. These watcher nodes cannot be treated as an endpoint trusted for authentication.

Outside the enterprise.

Inside the enterprise.

If your watcher node computer lies inside the perimeter network, using Trusted Server authentication can greatly reduce administration tasks by maintaining a single certificate, rather than using numerous user account passwords.

To configure Trusted Server authentication, you must first create a trusted application pool to host the watcher node computer. After you’ve created the trusted application pool, you must then configure synthetic transactions on that watcher node to run as trusted applications.

note참고:
A trusted application is an application that is given trusted status to run as part of 비즈니스용 Skype 서버 2015, but is not a built-in part of the product. Trusted status means that the application will not be challenged for authentication each time it runs.

To create a trusted application pool, open the 비즈니스용 Skype 서버 관리 쉘 and run a command similar to this:

New-CsTrustedApplicationPool -Identity atl-watcher-001.litwareinc.com -Registrar atl-cs-001.litwareinc.com -ThrottleAsServer $True -TreatAsAuthenticated $True -OutboundOnly $False -RequiresReplication $True -ComputerFqdn atl-watcher-001.litwareinc.com -Site Redmond
note참고:
For details about the parameters in the preceding command, type the following from the 비즈니스용 Skype 서버 관리 쉘 prompt:
Get-Help New-CsTrustedApplicationPool -Full | more

After creating the trusted application pool, you can then configure the watcher node computer to run synthetic transactions as a trusted application by using the New-CsTrustedApplication cmdlet and a command similar to this:

New-CsTrustedApplication -ApplicationId STWatcherNode -TrustedApplicationPoolFqdn atl-watcher-001.litwareinc.com -Port 5061

When this command completes and the trusted application is created, you must then run the Enable-CsTopology cmdlet to make sure that the changes take effect:

Enable-CsTopology

After running Enable-CsTopology, restart the computer.

To verify that the new trusted application has been created, type the following at the 비즈니스용 Skype 서버 관리 쉘 prompt:

Get-CsTrustedApplication -Identity "atl-watcher-001.litwareinc.com/urn:application:STWatcherNode"

Each watcher node that uses TrustedServer authentication must have a Default certificate assigned by using the 비즈니스용 Skype 서버 Deployment wizard.

To assign a Default certificate:

  1. Click Start, click All Programs, click 비즈니스용 Skype 서버 2015, and then click 비즈니스용 Skype 서버 Deployment Wizard.

  2. In the 비즈니스용 Skype 서버 Deployment Wizard, click Install or Update 비즈니스용 Skype 서버 System, and then click Run under the heading Request, Install, or Assign Certificate.

note참고:
If the Run button is disabled, you may need to first click Run under Install Local Configuration Store.

Do one of the following:

  • If you already have a certificate that can be used as the Default certificate, click Default in the Certificate wizard, and then click Assign. Follow the steps in the Certificate Assignment wizard to assign that certificate.

  • If you need to request a certificate for use the Default certificate, click Request, and then follow the steps in the Certificate Request wizard to request that certificate. If you use the default values for the Web Server certificate, you get a certificate that you can assign as the Default certificate.

After you have restarted the watcher node computer and configured a certificate, you must run the file Watchernode.msi. (You must run Watchernode.msi on any computer where both the Operations Manager agent files and the 비즈니스용 Skype 서버 2015 core components are installed.)

To install and configure a watcher node:

  1. Open the 비즈니스용 Skype 서버 Management Shell by clicking Start, clicking All Programs, clicking 비즈니스용 Skype 서버 2015, and then clicking 비즈니스용 Skype 서버 Management Shell.

  2. In the Management Shell, type the following command and then press ENTER (be sure and specify the actual path to your copy of Watchernode.msi):

C:\Tools\Watchernode.msi Authentication=TrustedServer
note참고:
You can also run Watchernode.msi n from a command window. To open a command window, click Start, right-click Command Prompt, and then click Run as administrator. When the command window opens, type the same command shown in step 2, above.
important중요:
In the preceding command, the name/value pair Authentication=TrustedServer is case-sensitive. It must be typed exactly as shown. For example, this command will fail because it does not use the correct letter casing:
C:\Tools\Watchernode.msi authentication=trustedserver

TrustedServer mode can be used only with computers that lie inside the perimeter network. When a watcher node runs in TrustedServer mode, administrators do not have to maintain test user passwords on the computer.

If your watcher node computer lies outside the perimeter network then you must follow a slightly different procedure in order to configure that watcher node to run synthetic transactions: in particular, you should not create a trusted application pool or a trusted application. That means that you will need to complete the next two tasks.

If your watcher node lies outside the perimeter network, you must add the Network Service account to the RTC Local Read-only Administrators group on the watcher node computer by completing the following procedure on the watcher node:

  1. Click Start, right-click Computer, and then click Manage.

  2. In Server Manager, expand Configuration, expand Local Users and Groups, and then click Groups.

  3. In the Groups pane, double-click RTC Local Read-only Administrators.

  4. In the RTC Local Read-only Administrators Properties dialog box, click Add.

  5. In the Select Users, Computers, Service Accounts, or Groups dialog box, click Locations.

  6. In the Locations dialog box, select the name of the watcher node computer, and then click OK.

  7. In the Enter object names to select box, type Network Service, and then click OK.

  8. In the RTC Local Read-only Administrators Properties dialog box, click OK, and then close Server Manager.

  9. Restart the watcher node computer.

Your next step is to run the file Watchernode.msi:

  1. Open the Microsoft Skype for Business Server 2015 Management Shell. Click Start, click All Programs, click Microsoft Skype for Business Server 2015, and then click Skype for Business Server Management Shell.

  2. In Skype for Business Server Management Shell, type the following command, and then press ENTER (be sure to specify the actual path to your copy of Watchernode.msi):

    c:\Tools\Watchernode.msi Authentication=Negotiate
    
note참고:
As mentioned previously, Watchernode.msi can also be run from a command window. To open a command window, click Start, right-click Command Prompt, and then click Run as administrator. When the command window opens, type the same command shown in step 2, above.

The Negotiate mode is used any time the watcher node cannot be set up as a trusted application pool. In this mode, administrators will need to manage test user passwords on the watcher node.
