distributed system stress and load testing tool.

The tool simulates a traffic from test cluster towards system-under-test (SUT). The purposes of tool is validation of system performance and scalability, while spawning huge number of concurrent sessions.

See specification

The project requires Erlang/OTP development environment here and essential development tool sets. The project provides binary files for Linux x86_64 and MacOS 10.10.x platforms.

Use following commands to compile and make distributable package for your platform. The output is self-deployable bundle package typhoon-{vsn}+{head}.{arch}.{plat}.bundle

   make
   make pkg

It is possible to assemble cross platform packages on MacOS. However it requires docker tool kit and docker image with Erlang/OTP environment.

   make
   make pkg PLAT=Linux 

See config file

The tool provides rest api to manage load and stress test scenarios using curl command line utility and implement html interface to visualize measurements. The load scenario is json file

Use browser to inspect the progress of the executed test http://localhost:8080/:id once test specification is defined to the cluster.

curl -XPUT \
   http://localhost:8080/scenario/:id \
   -H 'Content-Type: application/json' \
   -d @myload.json

curl -XDELETE \
   http://localhost:8080/scenario/:id

curl -XGET \
   http://localhost:8080/scenario/:id

curl -XGET \
   http://localhost:8080/scenario/:id/spawn

• The current version is optimized for http(s) protocol only, support for other protocols and protocol plug-in interface is planned for future releases

• Scenario files are stored in-memory. However cluster manages 3 replicas.

• The access to the tool shall not be exposed to public networks.
