Siege

Siege is an open source stress / regression test and benchmark utility. 

siege -c100 -t30S -d10 -b -v aman.info.tm

Some Extensions 

--header="Cookie: SESSb43b2d1d084de3872c89b0b125b64564=Jafuk06rppYAXIxWaU0LY2VmqxN997DsKU3BSgfArCM" 
-f /path/to/some-urls.txt

The some-urls.txt file is just a simple list of URLs on newlines: 

http://www.mywebsite.com/about-us
http://www.mywebsite.com/contact-us

Httperf

Installation: 

sudo apt install httperf

Usage: 

httperf --server waf.avitest.com --port 80 --num-conns 100 --rate 10 --timeout 1

Curl

curl -s -o /dev/null -w "%{http_code}" http://waf.avitest.com
seq 100 | parallel -j0 curl -s -o /dev/null -w "%{http_code}" http://waf.avitest.com

for i in `seq 1 99999`; do echo "Status Code:"; curl -s -o /dev/null -w "%{http_code}" https://10.1.1.1; sleep 1; done

Apache Benchmark

ab -t 1 -n 1000 -c 300 http://waf.avitest.com/

Increase Apache MaxClients (now called MaxRequestWorkers in new versions) on Backend Server: 

sudo nano /etc/apache2/mods-available/mpm_event.conf
MaxRequestWorkers         1000
ServerLimit         565

Locust

Installation: 

sudo apt-get update
sudo apt-get -y install python-pip python-dev libxml2-dev libxslt-dev
sudo pip install locustio

Install pyzmq for tests across multiple servers to increase the testing capacity: 

sudo pip install pyzmq

Set file limit to unlimited to ensure there is no OS problems with files at concurrency: 

ulimit -n 9999


Locust File

Single “task” which gets a specific webpage: 

from locust import HttpLocust, TaskSet, task

class UserBehavior(TaskSet):

    @task
    def get_something(self):
        self.client.get("/something")

class WebsiteUser(HttpLocust):
    task_set = UserBehavior


The test below logs a user in to groupster then requests what will be their home page 1 time for every 3 times it requests a group page: 

from locust import HttpLocust, TaskSet

def login(l):
    l.client.post("/login/process", {"email":"me@someemail.com", "pass":"password"})

def index(l):
    l.client.get("/")

def group(l):
    l.client.get("/group/1/")

class UserBehavior(TaskSet):
    tasks = {index:1, group:3}

    def on_start(self):
        login(self)

class WebsiteUser(HttpLocust):
    task_set = UserBehavior
    min_wait=5000
    max_wait=9000

Executing

Upload the locust test file (Click here to see how to make a locust testfile) Exec this command (this only starts the interface to control the tests it doesnot actually start a test): 

locust -f ./locastfile.py --host=http://somedomain.io --master

Go to the web interface to control the test variables and to start and stop it. 

http://localhost:8089

Distributed Mode

Running locally is fine for basic testing and getting started with Locust, but most applications will not receive a significant load if you’re just running it from your local machine. It’s almost always necessary to run it in distributed mode. This is easy to do with a couple AWS nodes.

After installing Locust and moving your locustfile.py to all nodes, you can start the “master” node: 

locust --host=http://localhost:5000 --master

Then start any “slave” nodes, giving them a reference to the master node: 

locust --host=http://localhost:5000 --slave\
 --master-host=192.168.10.100
