WTG-SEAL
A Web Traffic Generator based on SURGE, Statistics and Locust
Overview
WTG-SEAL is a web traffic generator based on a statistical approach inspired by SURGE [1] and implemented using 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.
Getting Started
Installing with pip
To install the latest release of WTG-SEAL, just run
pip install wtg-seal
Requirements
In order to generate your locustfile.py
using WTG-SEAL, you will need of two
text files formatted as follow:
Documents Definitions
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
following content:
1
5 8
maps to a document represented by a single file 1.txt
and another document
represented by the files 5.txt
and 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.
Server Side
Considering the previous example, it would be necessary that files named
1.txt
, 5.txt
and 8.txt
exist on a web-server to where the requests will be
made.
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 locustfile.py
.
From here, you will rely on Locust to generate the web traffic towards a web server of your choice. Just run
locust
and access the URL provided on your screen. For more information, see Locust documentation.
