Parameters

Test-CsPresence is an example of a Lync Server 2010 synthetic transaction. Synthetic transactions are used in Lync Server to verify that users are able to successfully complete common tasks such as logging on to the system, exchanging instant messages, or making calls to a phone located on the public switched telephone network (PSTN). These tests can be conducted manually by an administrator, or they can be automatically run by an application such as Microsoft System Center Operations Manager (formerly Microsoft Operations Manager).

Synthetic transactions are typically conducted in two different ways. Many administrators will use the CsHealthMonitoringConfiguration cmdlets to set up test users for each of their Registrar pools. Typically, these are test accounts and not accounts belonging to actual users. With these user accounts configured for a pool, administrators can simply run a synthetic transaction against that pool without having to specify the identities of (and supply the credentials for) the user accounts involved in the test.

Alternatively, administrators can run a synthetic transaction using actual user accounts. For example, if two users are unable to exchange instant messages, an administrator can run a synthetic transaction using the two user accounts in question (as opposed to a pair of test accounts) and try to diagnose and resolve the problem. If you decide to conduct a synthetic transaction using actual user accounts, you will need to supply the logon names and passwords for each user.

Test-CsPresence is used to determine whether a pair of test users can log on to Lync Server and then exchange presence information. To do this, the cmdlet first logs the two users on to the system. If both logons succeed, the first test user then asks to receive presence information from the second user. The second user publishes this information, and Test-CsPresence verifies that the information was successfully transmitted to the first user. After the exchange of presence information, the two test users are then logged off from Lync Server.

Who can run this cmdlet: To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "Test-CsPresence"}

None. Test-CsPresence does not accept pipelined input.

Test-CsPresence returns an instance of the Microsoft.Rtc.SyntheticTransactions.TaskOutput object.

-------------------------- Example 1 --------------------------

	Copy Code
Test-CsPresence -TargetFqdn atl-cs-001.litwareinc.com

The preceding example checks to see if a pair of preconfigured test users can log on to the pool atl-cs-001.litwareinc.com; after the test users are logged on, Test-CsPresence then checks to see if the two users are able to exchange presence information. This command will work only if test users have been defined for the pool atl-cs-001.litwareinc.com. If they have, then the command will determine whether the first test user can log on to the system and then check to see if this user can exchange presence information with the second test user defined for the pool.

If a Registrar has not been defined then the command will fail because it will not know which users to employ when doing the test. If you have not defined test users for a pool, then you must include the SubscriberSipAddress and PublisherSipAddress parameters in addition to the corresponding credentials for the users acting as the presence subscriber and the presence publisher. Test-CsPresence will then conduct its checks using the two specified users.

-------------------------- Example 2 --------------------------

	Copy Code
$cred1 = Get-Credential "litwareinc\pilar" $cred2 = Get-Credential "litwareinc\kenmyer" Test-CsPresence -TargetFqdn atl-cs-001.litwareinc.com -SubscriberSipAddress "sip:pilar@litwareinc.com" -SubscriberCredential $cred1 -PublisherSipAddress "sip:kenmyer@litwareinc.com" -PublisherCredential $cred2

The commands shown in Example 2 test the ability of a pair of users (litwareinc\pilar and litwareinc\kenmyer) to log on to Lync Server, and then exchange presence information. To do this, the first command in the example uses the Get-Credential cmdlet to create a Windows PowerShell credential object containing the name and password of the user Pilar Ackerman. (Because the logon name litwareinc\pilar has been included as a parameter, the Windows PowerShell Credential Request dialog box will only require the administrator to enter the password for the Pilar Ackerman account.) The resulting credential object is then stored in a variable named $cred1. The second command does the same thing, this time returning a credential object for the Ken Myer account.

With the two credential objects in hand, the third command in the example determines whether or not the two users can log on to Lync Server and exchange presence information. To carry out this task, Test-CsPresence is called, along with the following parameters: TargetFqdn (the FQDN of the Registrar pool); SubscriberSipAddress (the SIP address for one test user); SubscriberCredential (the Windows PowerShell object containing the credentials for this same user); PublisherSipAddress (the SIP address for the other test user); and PublisherCredential (the Windows PowerShell object containing the credentials for the other user).
