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
- Go to the directory with locust file & execute below command:
- This only starts the interface to control the tests it does not 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
- To generate significant load it is almost always necessary to run it in distributed mode.
- Master server do not simulate any user itself.
- For this we have to start one or more slaves using –slave flag
- Both the master and each slave machine, must have a copy of the locust test scripts when running Locust distributed.
- Run below command on each slave nodes as well
ulimit -n 9999
Start “master” node:
locust --host=http://somedomain.io --master
Then start any “slave” nodes, giving them a reference to the master node:
locust --host=http://somedomain.io --slave --master-host=192.168.10.100
Without WebUI
Runs the cli mode as below:
locust -f locustfile.py --no-web -c 1000 -r 100 --run-time 1h30m
In Distributed mode it will wait until all slave nodes have connected before starting the test:
locust -f locustfile.py --no-web -c 1000 -r 100 --run-time 1h30m --expect-slaves
