Change the following two lines in scripts/update-review-statistics.py to match your server:

SERVER_URL="http://127.0.0.1:5000"
SERVER_KEY="SECRET"

Then run the stats like this:

$ cd security-review-statistics
$ virtualenv env
$ source env/bin/activate
(env) $ pip install requests
(env) $ cd scripts
(env) $ ./update-review-statistics.py username@mozilla.com

Enter your bugzilla account password and the script will collect statistics and report them back to the server to make fancy charts.
