Question

我使用Lync客户端SDK 2013和UCMA 4.0创建了应用程序。现在我用大量用户测试我的应用程序。如何使用UCMA或Lync客户端SDK模拟大量客户端？

Answer 1

这取决于你想要什么＆＃34;模拟＆＃34;。

如果您只是想要呼叫流量，则sipp，但这只是简单的SIP呼叫，并不能真正反映实际的Microsoft Lync客户端。

据我所知，Microsoft并未在Lync中提供任何负载测试工具。你必须根据你想要的东西自己生成它们＆＃34;模拟＆＃34;。

使用UCMA可信应用程序，您应该能够启动并使用大量用户端点来模拟＆＃34;常见的lync服务（如随机更改状态，拨打电话，发送即时消息等）。您必须自己创建这样的应用程序。

Answer 2

我在UCMA中创建了一个工具来对我的所有应用程序进行压力测试。

制作简单，由两部分组成。这个例子是一个用于呼叫的压力测试器。当然，您可以使用此示例轻松制作另一个。

我们创建platform，按照我们的Set-CsTrustedApplication。

var platformSettings = new ProvisionedApplicationPlatformSettings("InnixiTester", "urn:application:innixitester"); 
var collabPlatform = new CollaborationPlatform(platformSettings);

collabPlatform.EndStartup(collabPlatform.BeginStartup(null, null));

好的，我知道我在这里做的是一个错误的链接，将Begin和End编成一行代码。但是，这只是一个代码示例。我邀请你阅读Tom Morgan的文章，他解释了为什么像我这样做是不好的。

我们在这里使用Parallel loop来创建我们所有的用户端点。这样，它就会更快。

/*
 * Proprieties of the class 
 */

private AutoResetEvent _waitForStressTestToFinish = new AutoResetEvent(false);
private List<UserEndpoint> _listUserEndpoints = new List<UserEndpoint>();
private int _maxUsers = 200;
private int _tickTotal;
private int _tickCount;
private int _nbrCallsByIntervall;

/*
 * End
 */

_maxUsers = 200; // Nbr max of users
const var callsTotal = 200; // Nbr of total call
const var timeToTest = 30; // Total time to test
const var intervalOfCalls = 5; // We want to make our calls between specific intervals


Parallel.For(0, _maxUsers, i => 
        {
            CreateUserEndpoint(collabPlatform, i.ToString());
        });

您只需在此处创建UserEndpoint。方案是我在活动目录中的用户是stressuser0到stressuser200。扩展名从+14250到+1425200

private void CreateUserEndpoint(CollaborationPlatform cp, string iteration)
{
    try
    {
        UserEndpointSettings settingsUser = new UserEndpointSettings($"sip:stressuser{iteration}@pferde.net", "pool2010.pferde.net", 5061);

        settingsUser = InitializePublishAlwaysOnlineSettings(settingsUser);

        var userEndpoint = new UserEndpoint(cp, settingsUser);

        userEndpoint.EndEstablish(userEndpoint.BeginEstablish(null, null));

        PublishOnline(userEndpoint);

        _listUserEndpoints.Add(userEndpoint);

        Console.WriteLine($"The User Endpoint owned by URI: {userEndpoint.OwnerUri} was created\n");
    }
    catch (Exception)
    {
        Console.WriteLine($"failed to create for --> sip:stressuser{iteration}@pferde.net");
        throw;
    }

}

private UserEndpointSettings InitializePublishAlwaysOnlineSettings(UserEndpointSettings settings)
{
    settings.AutomaticPresencePublicationEnabled = true;
    settings.Presence.PreferredServiceCapabilities.AudioSupport = CapabilitySupport.Supported;

    return (settings);
}

现在是时候拨打电话了！我们将使用计时器编写一个简单的算法。将计算X时间以及Y呼叫和Z间隔需要进行多少次呼叫。

   Console.WriteLine("Tape a key to place calls...");
   Console.ReadKey();

   PlaceCalls(callsTotal, timeToTest, intervalOfCalls);

   _waitForStressTestToFinish.WaitOne();

   }
  catch (Exception ex)
 {
 Console.WriteLine($"Shutting down platform due to error {ex}");
 ShutdownPlatform(collabPlatform);
 }
 ShutdownPlatform(collabPlatform);
}

private void PlaceCalls(int callsMax, int timeMax, int timeIntervall)
{
    _tickTotal = timeMax / timeIntervall;
    _nbrCallsByIntervall= callsMax / _tickTotal;

    Console.WriteLine($"_nbrCallsByIntervall --> {_nbrCallsByIntervall}");

    var timeIntervalTimespan = new TimeSpan(0, 0, 0, timeIntervall);
    _timer = new Timer(timeIntervalTimespan.TotalMilliseconds);
    _timer.Elapsed += new ElapsedEventHandler(_timer_Elapsed);
    _timer.Enabled = true;
}


void _timer_Elapsed(object sender, ElapsedEventArgs e)
{
    if (_tickCount < _tickTotal)
    {
        Console.WriteLine($"\n Pause Timer | On {_tickCount} to {_tickTotal}\n");
        _timer.Enabled = false;
        for (var i = 0; i <= _nbrCallsByIntervall - 1; ++i)
        {
            ConversationSettings convSettings = new ConversationSettings();
            Conversation conversation = new Conversation(_listUserEndpoints[generateNumber(0, _listUserEndpoints.Count)], convSettings);

            var audioVideoCall = new AudioVideoCall(conversation);
            CallEstablishOptions options = new CallEstablishOptions();

            var gNbr = generateNumber(0, _listUserEndpoints.Count);
            try
            {
             // Here I'm calling a single phone number. You can use GenerateNumber to call stressusers each others. But you have to extend your code to accept the calls coming.
                audioVideoCall.BeginEstablish($"3322", options, null, audioVideoCall);
            }
            catch (Exception)
            {
                Console.WriteLine("Fail to Call the remote user...");
                throw;
            }
           Console.WriteLine($"Call--> +1425{gNbr}.Counter--> {_tickCount} Ticket--> {_tickTotal} and thread id {Thread.CurrentThread.ManagedThreadId}");
        }
        _tickCount++;
        _timer.Enabled = true;
        Console.WriteLine("\n reStart Timer \n");
    }
    else
    {
        Console.WriteLine("\n!!! END Stress test !!!\n");
        _timer.Enabled = false;
        _waitForCallToEstablish.Set();
    }
}

private int generateNumber(int min, int max)
{
    var r = new Random();
    Thread.Sleep(200);
    return (r.Next(min, max));
}

如何使用UCMA模拟大量客户端进行负载测试？
