Multi-threaded load Generator for Azure Service Bus and Event Hubs (superseded by a dotnet core version)

Note: it’s been superseded by a rewritten dotnet core version available here

This console app generates random payload and inserts it into an Azure Service Bus Queue or a Topic or an Azure Event Hub. Every payload message is a JSON consistsing of a UTC timestamp and a random string payload:

  1. {"dt":1513815044440,"payload":"<random string as per message size>"}

Note: do not forget to add ;TransportType=Amqp to your connection string to enforce AMQP 1.0

Software prerequisites:

  1. Visual Studio 2015 (or higher)

Running this sample

  1. Clone this repository or download the zip file.
  2. Open the solution, perform nuget restore and build

  3. Usage:
    ```
    .\LoadGenerator.exe

    -t, —threads Required. (Default: 5) Threads to spawn.
    -s, —size Required. (Default: 1024) JSON Payload size, real

    1.                      size in bytes = 35 + size

    -m, —messagestosend Required. (Default: 100) Messages to send in each

    1.                      thread before termination, 0 for infinity

    -c, —connectionstring Required. Event Hub or Service Bus Namespace

    1.                      connection String. If Event Hub, make sure it is the
    2.                      Namespace's connection string, not the Event Hub's

    —name Event Hub or Queue or Topic Name
    —checkpoint (Default: 100) Checkpoint - log to console every N

    1.                      messages

    -b, —batchmode (Default: True) Send messages in batches of 

    1.                      --batchsize size

    —batchsize (Default: 100) Determines the size of the batch if 

    1.                      using batch mode
  2. ## Example
  3. The following command line generates load in batches of 200 messages using 10 parallel threads, each message size is 150+35 bytes. The code will run infitinely until SIGTERM or Ctrl+C is received

.\LoadGenerator.exe —threads 10 —size 150 —messagestosend 0 —connectionstring “Endpoint=sb://latencytest.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=*;TransportType=Amqp” —name eh1 —checkpoint 100 —batchmode True —batchsize 200
