Locust is an open source tool for load testing of web applications. The software is optimized to support the emulation of a large number of users, without using a large number of threads by using an event-driven model. Locust allows writing specific user behaviour for load testing through plain Python programming language scripts.
The following figure presents the possible command-line parameter configuration of the load testing tool.

In case you need to run the Python scripts from a VM you will need to clone the repository and install the Python requirements.txt by running the following commands.
#!/bin/bash
git clone https://github.com/unifiedstreaming/streaming-load-testing.git

#!/bin/bash
git clone https://github.com/unifiedstreaming/streaming-load-testing.git
cd streaming-load-testing
make buildRun a simple load testing example using the built docker image. The following
command will create a performance test and creates a folder with csv files
results in the folder test-results.
