Websocket stress testing made beautiful

Hello!

This repository holds WSStat, a websocket monitoring and visualization tool written in Python 3.3+, using the great AsyncIO, Websocket, and Urwid libraries 😎 .

It aims to make diagnosing problems and understanding your websocket infrastructure easy and beautiful.

There are still a few edges and whatnot since it's fairly new, and some functionality doesn't exist (yet), but that's where I'm hoping the community can help.

I'm actively looking for feedback

The core of WSStat was written to be modular with extensibility in mind. Want a web API to gather statistics while it runs? How about a websocket server that pushes statistics from multiple workers to one place? Threshold based alerting? Slack integration? File a ticket and we'll kick it around!

It should go without saying, but pull requests are absolutely welcome!

Now, a demo

When you pass the --demo flag to WSStat, it will spin up an asynchronous websocket server on port 65432 point the websocket monitors to that server, allowing you to see functionality with a real websocket server.

Installation

Install from pip - pip install wsstat

Note: if you have python 2 and 3 installed on the same system, you have to use pip3 install wsstat!

The installation should be 100% straight forward and work fine. If that's not the case, please file a ticket!

Please note: WSStat currently only works on Python >= 3.3, and won't install on python 2.7, which is a known limitation.

Usage

Using wsstat is pretty straight forward, and it only has a few knobs (for now). If you want to try wsstat out and don't have a websocket infrastructure handy, you can just pass in --demo to have wsstat set up a server for you!

Other than that, you can adjust the total number of connected clients with -n, the number of simultaneous sockets trying to connect at once with -c, or pass in an arbitrary header (for things like authentication) with -H.

$ wsstat -h
usage: wsstat [-h] [-n TOTAL_CONNECTIONS] [-c MAX_CONNECTING_SOCKETS]
              [-H HEADER] [--demo] [-i]
              [websocket_url]

positional arguments:
  websocket_url         The websocket URL to hit

optional arguments:
  -h, --help            show this help message and exit
  -n TOTAL_CONNECTIONS, --num-clients TOTAL_CONNECTIONS
                        Number of clients to connect - default 250
  -c MAX_CONNECTING_SOCKETS, --max-connects MAX_CONNECTING_SOCKETS
                        Number of connections attempted simultaneously -
                        default 15
  -H HEADER, --header HEADER
                        Pass a custom header with each websocket connection
  --demo                Start a demo websocket server and point wsstat at it
  -i, --insecure        Don't validate SSL certificates on websocket servers
