#Sonar

Simple script deployed in each country to test performance accessing major sites simulating a real user. Data is reported to statshub and shown at lantern-dashboard.

Deploy

PhantomJS is required to test the sites and report to statshub.

Install dependencies

sudo apt-get install -f libfontconfig

To test performance of Lantern network, headless version of Lantern is required.

See flash-build repo for details.

Run

PhantomJS is not considered pretty stable. It may crashes or takes unrealistic long time to load a page. So instead of run one phantomjs instance forever, we can run it periodly. Below is an example to run it every 5 minutes.

[fffw@hyperion ~]$ crontab -l
0-59/5  *       *       *       *       (cd /home/fffw/sonar/; phantomjs --proxy localhost:8787 sonar.js 2.0.0-beta4 >> 2.0.0-beta4.log 2>&1)

We can run several instances of sonar to test performace of different Lantern versions. Just run lantern at different proxy port and set PhantomJS proxy url accordingly.
