Using the Skype for Business Server 2015 Stress and Performance Tool
To run the Skype for Business Server 2015 Stress and Performance Tool, you'll need to be able to manage both users, contacts and user profiles, configure the tool for running, and then review the output or results that are produced by the tool.
There are four areas involved with running the Skype for Business Server 2015 Stress and Performance Tool (the executable is LyncPerfTool.exe):
Create Users and Contacts
You need to use the Skype for Business Server 2015 (SB 2015) User Provisioning Tool (UserProvisioningTool.exe) to create users and contacts for your stress and performance testing.
This is a list of helpful terms that might be useful as you read through the topics:
Organizational Unit - The Active Directory Domain Services (AD DS) organizational unit (OU).
Federated / Cross Pool - Users who can communicate with users from other Instant Messaging (IM) services.
Distribution Lists - Or DLs. These are objects in AD DS that contain a list of AD DS users. They're used to facilitate communications across groups of people.
Location Info Service - The Skype for Business Server 2015 service that, when it's enabled and configured per phone, allows for the retrieval of physical location for Enhanced 911 (E911) services.
U.S. Phone Numbers - Phone numbers assigned to user in addition to the SIP URI that's used for routing inbound and outbound calls in Reverse Number Lookup (RNL).
Create Users and Contacts by using UserProvisioningTool.exe
Note
Before you even begin, be absolutely sure you're logged in as a member of the Domain Admins security group to run this tool. You need to do this, because you're going to be creating Active Directory users.
You have to use the Skype for Business Server User Provisioning Tool to create users and contacts for load simulation.
The Skype for Business Server User Provisioning Tool is installed with the Skype for Business Server Stress and Performance Tool package. Be sure that the package installer (CapacityPlanningTool.msi) has been run on the Front End Server or the Standard Edition server you intend to test.
You can start the Skype for Business Server User Provisioning Tool by running the file UserProvisioningTool.exe (located at %InstalledDirectory%LyncStressAndPerfTool\LyncStress) on the Front End Server or on the Standard Edition server.
Important
When you create a large number of users (for example, 10,000 or more), run the UserProvisioningTool.exe. You'll need to do this because the tool will be creating and configuring new AD users.
When the User Provisioning Tool opens, click Configuration and select the Load Configuration.
To begin configuring users and contacts, load the default file included with the package, called "SampleData.xml". This will prepopulate fields with sample data that you'll need to change to make it relevant for your deployment.
If you have a preconfigured XML file that already contains your customized settings, you can load that file instead. Fill in the fields in the User Provisioning Tool, as described in the sections below.
To configure server options:
In the Front End Pool FQDN field, type the fully qualified domain name (FQDN) of the Standard Edition server, or the Front End pool where you want to host the users.
In the User Name Prefix field, type a prefix that you want to use to bust your user names for testing purposes (such as "TestUser").
In the Password field, type a password that will be used across all the test user accounts.
In the Account Domain field, type the domain name of your current AD domain (the one in which you want to create your test users).
In the Organizational Unit field, type the name of the AD domain where you want to create these test users. (If the OU doesn't already exist, it'll be created for you).
In the Phone Area Code field, type the three-digit area code to be used across all test user accounts. Make certain that the area code you chose doesn't conflict with other users' area codes in AD.
Click to select the Voice Enabled check box, if you want to enable the test users for Enterprise Voice.
In the Number of Users field, give the total number of test users you want to create.
In the Start Index field, give the starting number that'll be used as a suffix to the user name prefix (for example, the prefix is "TestUser", and the first name will end in "0" in the example below.)
Create Users button
When you click on the Create Users button, the input parameters you've entered are validated. If there are any validation errors, you'll be prompted to fix them. Or, if all the values are correct, users will start appearing in AD (in whichever OU you specified). You'll see a progress bar at the bottom of the tool as it runs. Don't close the application while the progress bar is active.
User creation takes time, so please plan accordingly. This process can take anywhere from several minutes for a few users, to a few hours for a large number of users.
If you don't have access to the AD Domain Controller in your test environment, you can still validate user creation by logging in as one of the users in the range of users you specified to create. Remember to use the prefix, and the suffix, along with the @sipDomain as the username. Here is an example: TestUser20@contoso.net .
Note
If the users already exist, clicking the Create Users button will update them with any configuration changes.
Delete Users button
When you click on the Delete Users button, the tab's input parameters will be validated. If there are validation errors, you'll be prompted to fix them, and if the input values are correct, the specified test users will be disabled and deleted from Active Directory. Again, a progress bar will appear on the bottom of this tab, and you shouldn't close the application while the progress bar is active.
Note
Only U.S.-formatted phone numbers are supported. Phone numbers are always assigned to users, and all users created by UserProvisioningTool.exe are enabled for Enterprise Voice by default. Any scenarios that use the phone number, such as Conferencing Auto Attendant or UC-PSTN calls, use this phone number to properly route calls. For this reason, every user must have a unique phone number .
Note
If you have to create users twice, the command will fail unless you use a different area code, or if the previous users have been disabled by using the Disable-CsUser cmdlet.
Important
Before you create contacts, you first need to complete user replication (which is done from the Users tab).
Important
If you've just created your users, you'll need to wait until Skype for Business Server replication completes and populates the user accounts in the database. If the users haven't finished replicating, you'll see an error. You'll know when users have finished replicating if the Skype for Business Server 2015 Front End service has started, or by successfully running the Get-CsUser cmdlet on the last user of the total number you specified.
Contacts Creation tab
This tab lets you give users' contacts details for your testing.
To configure users' contacts, do the following:
In the Average Contacts per User field, enter the average number of contacts to populate in contact lists for each user.
Select the Fixed check box if you want to create an equal number of contacts for every user. If you want to vary the number of contacts created for users, clear that check box.
In the Average Contact Groups per User field, enter the number of contact groups per user. This number needs to be smaller than Average Contacts per User.
In the Federated / Cross Pool Contacts Percentage field, give a number between 0 and 100. This percentage of contacts will be created with the federated users.
In the Federated / Cross Pool User Prefix field, give the username for federated users that will be added to the contact lists of local users.
In the Federated / Cross Pool User SIP Domain field, give the SIP Domain Name of the federated users.
In User Creation tab make sure the information is correct. Your contacts will be created from values on the User Creation tab.
Click Create Contacts to begin the contact creation. This process can take several minutes. After it completes, a dialog box will appear with the message, "Operation Completed Successfully." You can validate the contacts that were created by logging on as a user that was created from the User Creation tab.
Note
After the contacts are created, this tool will restart all the Front End Servers in the target pool. It may take longer (up to 2 hours) for the Front End Servers to start, depending on how many contacts were created by this operation.
Distribution List
The Skype for Business Server 2015 Stress and Performance Tool can simulate the Distribution List (DL) expansion feature in the Skype for Business 2015 client. You can skip this step if you don't intend to enable DL expansion in the User Provisioning tool.
The Distribution List tab allows you to create DLs that the Stress and Performance Tool will use for Distribution List Expansion feature. Before creating DLs, Skype for Business Server 2015 needs to be deployed, including having run ForestPrep. If this isn't done, the DL attributes will not exist in the AD schema, so the tool won't be able to create DLs.
To configure Distribution Lists:
In the Number of Distribution Lists field, give the total number of DLs you want to create (The recommendation here is that you start with a value that is double the number of users you have.).
In the Distribution List Prefix field, enter a prefix that all the DLs you create will have, for example testDL . That means, at 100 DLs, your DL names will look like: testDL0, testDL1, up to testDL99.
In the Minimum Members in a Dist. List field, enter the minimum number of users to put in each DL.
In the Maximum Members in a Dist. List field, enter the maximum number of users to add in each DL.
Create Distribution Lists button
When you click the Create Distribution Lists button, the tool queries Active Directory to see if distribution lists matching the prefix and numbers already exist. The tool creates any DLs that don't already exist. When adding members to these newly created Distribution Lists, it'll choose the users from the range specified on the User Creation tab.
Location Info Service Config tab
The Skype for Business Server 2015 Stress and Performance Tool can also generate dummy configuration files for the Location Information Service. Note that the Location Information Service typically doesn't have significant performance impact on the servers.
If you choose to test this feature, fill in the values in the form and click the Generate LIS Config Files button, which will create .CSV files called:
LIS_Subnet.csv
LIS_Switches.csv
LIS_Ports.csv
LIS_WAP.csv
To import these files into the LIS database use these PowerShell cmdlets:
Set-CsLisSubnet
Set-CsLisSwitch
Set-CsLisPort
Set-CsWirelessAccessPoint
Configure User Profile
After your users are created (via the User Creation Tool) you can configure user profiles with the Skype for Business Server 2015 Load Configuration tool (UserProfileGenerator.exe).
Running the Skype for Business Server 2015 Load Configuration tool
Start the Load Configuration tool (UserProfileGenerator.exe) and fill in the tabs. This tool creates a directory for each of the client computers that you'll need to run your simulations. Each client directory comes with a script to start the Skype for Business Server 2015 Stress and Performance tool (LyncPerfTool.exe). The sections below will give examples of how to fill in the fields on each tab of the Skype for Business Server 2015 Load Configuration tool.
Important
The user-specific values used in the Load Configuration tool (UserProfileGenerator.exe) must match the values specified in the Skype for Business Server 2015 User Creation Tool (UserProvisioningTool.exe) for the pool.
Common Configuration tab
The Common Configuration tab of the Load Configuration Tool is shown below. Fill in the fields of the Common Configuration tab, as described in the following steps.
In the Number of Available Machines field, type the number of computers you want to use to run the Stress and Performance tool (LyncPerfTool.exe). We recommend that you have one computer for every 4500 users you'll be simulating, but that number may vary if you reduce the load level, or use only a subset of the tool's available features (Load levels are set on the General Scenarios tab).
In the Prefix for User Names field, enter a prefix for the user name field of all users. To log in the Uniform Resource Identifier (URI) will be: UserPrefix[User Start Index...(Number Of Users-1)]@User Domain , for example, myUser009@Contoso.com.
In the Password for All Users field, enter the password used during creation of the users. If you leave this field empty the username will be set as the password.
In the User Start Index field, enter the index of the first user to be configured. You can configure different ranges for different types or levels of load, but you must run the Load Configuration tool (UserProfileGenerator.exe) once per the range you want to configure.
In the Number of Users field, enter the total number of users you're going to configure.
In the User Domain field, enter the domain used for the SIP URI. This is used to construct the SIP URI of each user to log on to the Skype for Business Server 2015 Front End Server or Standard Edition server, and may be different from the Account Domain.
In the Account Domain field, enter the AD DS domain logon.
In the MPOP Percentage (Multiple Point of Presence percentage) field, give a value for the percentage of users that are logged on from multiple machines or devices, for example 10 percent.
Enter the maximum number of concurrent endpoints in the Sign in Per Second (per Instance) field. This is the maximum number of log ins for your users, and the recommendation is a rate of less than/equal to 2 per second (<=2).
In the Access Proxy or Pool FQDN field, enter the fully qualified domain name (FQDN) of the server you want the clients to connect to. If the users are logging on externally, you'll need to type the access proxy. If the users are internal, give the FQDN of their Enterprise Pool or Standard Edition server.
In the Port field, enter the port that you want users to use for SIP (the default here is 5061).
For the External Network Server Settings field, give the Access Proxy or Pool FQDN and, again, the Port. These settings are used only for External endpoints load simulation.
General Scenarios tab
You can configure the load levels and parameters for each of the general scenarios offered by determining what you want to run or leave disabled. Here are your general options:
Note
Load level values for all fields but Local Information Services are Disabled, Low, Medium, High, or Custom. If you select any setting but Disabled, then configurations are generated for each client. High results in the max supported load on the server; medium is 60% of high load; low is 30%.
Instant Messaging - This includes peer-to-peer and conferencing; choose the appropriate value for Load Level.
Audio Conferencing - Choose a load level for audio conferencing only . Peer-to-peer calls will be tackled a little later in the Voice Scenarios section. Open the Advanced tab to enable MultiView.
Application Sharing - Choose a load level for application sharing.
Data Collaboration - Choose a load level for data collaboration, which includes data conferencing.
Distribution List Expansion - Click the Advanced button and fill in the field with the same values configured on the DL tab of the User Creation Tool (UserProvisioningTool.exe). Choose a load level.
Address Book Web Query - This is the address book lookup service rather than the address book file download. If you want to enable this for address book file downloads, click the Advanced button and set EnableABSDownload to True. Give a value for load level.
Response Group Service - Click the Advanced button and specify the URIs of the response groups you already created when you provisioned Response Group Service agents. You must choose at least one response group. To use more, separate the response groups with semicolons. Update RGSUriSuffixStartIndex and RGSUriSuffixEndIndex to the actual values. Choose a load level.
Location Information Services - Select a load level of either Enabled or Disabled.
Note
Each of the scenarios has an Advanced button located next to it, and a set of check boxes that enable variations to the default setting.
Choosing Ad-hoc will allow the tool to generate simulation of conferences that will be created throughout the hour.
Choosing Large Conf means that a Large Conference Scenario will be simulated.
External tells the tool to also simulate external users.
These buttons and check boxes are extra values specific to each scenario and will change the behavior of the Stress and Performance Tool and make customization possible.
For each scenario on the General Scenarios tab (except for Location Information Services), if the value of Load Level is Custom, then the conversation rate will be calculated using the corresponding field in the Advanced dialog box. The field name may differ, depending on the scenario, but the field description will state: NOTE This number will only be used if Custom is selected from the drop-down menu .
The values High, Medium, and Low, will alter the conversation rates per modality in line with the User Model that is a balance of all the scenarios. If there's a need to change the load level per modality due to a difference in expected usage, use a Custom conversation rate.
Voice Scenarios tab
This is the tab for configuration of all your voice-related scenarios.
Your options are:
VoIP - Click the Advanced button and add values for the PhoneAreaCode and LocationProfile (dial plan) fields. You'll also give a value for Load Level. If you choose a load level for VoIP or UC/PSTN Gateway enabled, then a public-switched telephone network (PSTN) to unified communications (UC) configuration file will be generated to simulate external calls.
UC/PSTN Gateway - You need to choose a Load Level value, and when you choose anything other than Disabled, you've also got to supply a value for PSTN area code by clicking the Advanced button. Click Add under the Mediation Server and PSTN. Make sure you have a route configured for the area code.
Tip
You can use either the Skype for Business Control Panel or Skype for Business Management Shell to verify your voice route configuration.
Conferencing Attendant - Supply a value for Load Level. Any value other than Disabled will enable the Telephone Number field. Enter the phone number of the Auto Attendant you want to use. Click Advanced and give a value for the LocationProfile field.
Call Parking Service - Here, supply a Load Level.
Mediation Server and PSTN - Each Mediation Server that you want to use needs its own PSTN simulator. After you've determined which client you're going to use for the simulator, configuration your Mediation Server to route calls to that computer on the PSTN Simulator you configured. Click the Add button to configure a value for the Mediation Server.
Note
Each scenario has an Advanced button located next to it. Advanced dialog boxes contain settings specific to each scenario that change the behavior of the Stress and Performance Tool and enable customization. > For each scenario on the Voice Scenarios tab, if the value of Load Level is Custom, then the conversation rate will be calculated by using the corresponding field in the Advanced dialog box. The field name may differ, depending on the scenario, but the field description will state: NOTE This number will only be used if Custom is selected from the drop-down menu .
Web App tab
Web App supports conferencing scenarios through the Unified Communications Web API (UCWA) server that's installed on a Front End server. Use the Web App tab to configure all web app-related scenarios. Options are:
General Web App Settings - Click the Additional Settings button and set the ReachTargetServerUrl to the Directory Pool virtual IP (VIP) of the Front End pool VIP.
Application Sharing - Select a value for Load Level.
Data Collaboration - Select a value for Load Level.
Instant Messaging - Select a value for Load Level.
Voice Conferencing - Select a value for Load Level.
Note
Each of the scenarios has an Advanced button located next to it. Advanced dialogs contain values specific to each scenario that will change the behavior of the Stress and Performance Tool and enable customization.> For each of the Web App scenarios, if the Load Level is Custom, then the value specified in the ConversationsPerHour field is used instead of the default.
Mobility tab
Use this tab to configure all of the mobility-related scenarios.
The options here are:
General Mobility Settings - Click Additional Settings and set the field UcwaTargetServerUrl to the Director Pool virtual IP (VIP) or the Front End pool VIP.
Presence and P2P Instant Messaging/Audio - Select a value for Load Level to enable the Mobility simulation.
Note
Each of the scenarios has an Advanced button located next to it. Advanced dialogs contain values specific to each scenario that will change the behavior of the Stress and Performance Tool and enable customization.> For each of the Mobility scenarios, if the Load Level is Custom, then the value specified in the ConversationsPerHour field is used instead of the default.
Summary tab
The Summary tab indicates which users to use for each of the scenarios.
The Summary tab indicates which users to use for each of the scenarios.
It's possible to manually configure user number ranges by selecting the Enable Custom User Range Generation check box, and then double-clicking the scenario in the table that has the User Range that you want to customize.
Check (RunClient.bat) Add sign-in delay when starting in order to include delays in the generated batch files to correspond to the sign-in rate. This is useful to prevent server overload when signing in a large number of users.
Click Generate Files and select the folder where you want to generate the configuration. A dialog box will appear when your files have been successfully created.
Run LyncPerfTool
You'll need to create users, contacts, and scenarios before running the Skype for Business Server 2015 Stress and Performance Tool (LyncPerfTool.exe). For details about using the tools to perform these actions, see Create Users and Contacts and Configure User Profile previously in this article. Running these tools will also generate a file that will run with the Stress and Performance tool as part of a batch file with the required parameters included.
Running the Skype for Business Server 2015 Stress and Performance tool
The Load Configuration tool (UserProfileGenerator.exe) creates a batch file that enables you to run the Stress and Performance tool (LyncPerfTool.exe) by registering performance counters and loading the XML configuration file. The batch file runs one instance of LyncPerfTool.exe per configuration file. To run the batch file follow these steps:
Run the Stress and Performance test
Copy the folder with the configuration folders and files inside to the directory that has LyncPerfTool.exe on each client computer. (For example, if you generated the configuration files in the folder named 1.28_13.16.16, copy that folder to the folder with LyncPerfTool.exe in it. Do this on each client.)
Navigate to the client folder and run the RunClient batch script. You can double-click the batch file in Windows Explorer and it will run all of the configuration files for that client. You can also run the script from a client folder by using the following syntax:
RunClient0.bat "C:\Program Files\Skype for Business Server 2015\LyncStressAndPerfTool\LyncStress"
To run the Stress and Performance tool directly, open a command prompt and type the following command at the command line (and when doing this for the first time, be sure to register the performance counters regsvr32 /i /n /s LyncPerfToolPerf.dll, as shown in the note later in this topic):
LyncPerfTool.exe /file:IM_client0.xml
To have the tool display the values in the configuration file, include the /displayfile parameter on the preceding command, so that it looks like this:
LyncPerfTool.exe /file:IM_client0.xml /displayfile
To end the process, press Ctrl+C.
Note
Before running the Stress and Performance tool directly, you must register the performance counters via the following command: regsvr32 /i /n /s LyncPerfToolPerf.dll
Note
Every instance of the Stress and Performance tool that you start will immediately begin signing in users, usually at a rate of one user per second.
The peak user sign-in rate for the pool is about 12 per second. This means that you shouldn't start more than 12 LyncPerfTool.exe instances at the same time while users are still signing in. One thousand users will take about 20 minutes to fully sign in at one per second.
Interpreting the Results
The Skype for Business Server 2015 Stress and Performance Tool has many counters that can help you understand what the client is doing, and whether it's encountering issues.
Client Counters
Each instance of LyncPerfTool.exe running has a separate instance of the counters. Each instance is named by its process ID. If clients are overloaded other issues can occur. To prevent these issues:
Monitor CPU and Memory usage on the client computers. If the CPU is consistently above 90 percent, reduce the number of users.
When the Memory footprint is high, you may run into issues if the Page File begins to run out of space. Verify that the Commit Charge is not hitting the limit on the computer. If you are running into Memory limits consider increasing the Page File size or reducing the number of users.
