Rosie
Rosie will help you load test your server.
Installation
For now, there is no streamlined way of installing this package. You can download the already built binaries in the build directory or clone this repository and build it yourself. Currently, this package does not work on Windows. If it gets traction, I will create an installation process and setup for all platforms.
How it works
Rosie creates “users” that will send requests from provided urls in random intervals. After all urls are sent, this user is done and a new one is created, repeating the process. For example, if you want 50 users to visit the urls that you provided, 50 users will send request concurrently in random intervals.
Usage
./rosie --user=20 --urls=https://facebook,https://google.com --interval=3-20
This command will create 20 virtual users that will send concurrent requests in a random interval between 3 and 20 seconds for 60 seconds. Every user first clicks the first URL, waits for the random number of seconds between 3 and 20, and then clicks the next One. After all URLs are “clicked”, user “logs out” and starts again.
./rosie --user=20 --urls=https://facebook,https://google.com --interval=3
This command will create 20 virtual users that will send concurrent requests in a random interval between 3 and
15 seconds for 60 seconds. When {min}-{max} notation is not specified, min defaults to 3 and max defaults to 15.
./rosie --user=20 --urls=https://facebook,https://google.com --interval=3 --throttle --duration=120
This command will create 20 virtual users that will send concurrent requests in a random interval between 3 and
15 seconds. --throttle will start “gently” creating 10 users per second as a preparation for real load testing.
--duration tells Rosie that this load testing will last for 120 seconds. 60 is the default.
Arguments
--urls (required)
A comma separated list of URLs that will be clicked i.e. requests will be sent to these URLs. At this moment, this package only supports GET requests.
--users : (optional|int)
Number of users to simulate. Defaults to 50.
--interval : (optional|string)
Interval with which this package will simulate a single user clicking on a URL. Notation is either --interval={min}
or --interval={min}-{max}. min cannot be less than 3.
--duration : (optional|int)
Amount of time load testing will last in seconds. Infinite load testing is not possible but you can specify any amount of seconds you want. Defaults to 60.
--throttle
Prepares server for load testing by creating 10 users per second. Useful if you don’t want to brutally DOS your server right away.
