A Web Traffic Generator based on SURGE, Statistics and Locust
In fact, it is expected that the input files for WTG-SEAL are the output files from SURGE, although one should be able to create their own files.
Installing with pip
To install the latest release of WTG-SEAL, just run
pip install wtg-seal
In order to generate your
locustfile.py using WTG-SEAL, you will need of two
text files formatted as follow:
A text file where each line describes a web document, which is defined as a
collection of one or more objects. For instance, a
docdef.txt with the
1 5 8
maps to a document represented by a single file
1.txt and another document
represented by the files
8.txt. Each document is identified by a
sequential number (the order it appears on the file, starting from 0).
Ideally, this is the
objout.txt file generated by SURGE.
Documents Requests Sequence
A text file where each line contains a document identifier (i.e an integer) in
the order they were to be requested to a web server. For instance, a
docseq.txt with the following content:
0 0 1 0
represents requests to documents 0, 0, 1, 0. This is used by WTG-SEAL to calculate the weight of each locust task.
Ideally, this is the
name.txt file generated by SURGE.
Considering the previous example, it would be necessary that files named
8.txt exist on a web-server to where the requests will be
Generating web traffic
Once you have the appropriate files, just run
wtgseal docdef.txt docseq.txt
This will create a file in the current directory named
From here, you will rely on Locust to generate the web traffic towards a web server of your choice. Just run
and access the URL provided on your screen. For more information, see Locust documentation.
For contributing or making your own modifications to the source code, run:
git clone https://github.com/mchoji/wtg-seal.git cd wtg-seal pipenv install -e . pipenv install --dev
In order to make sure the hooks will run, please don't forget to install the
cd wtg-seal pipenv install --dev pipenv run pre-commit install # update the hooks to the latest version pipenv run pre-commit autoupdate
