Alert testing

The settings.py has a default non-existent metric namespace for testing your alerters, in the skyline_test.alerters.test settings.ALERTS tuple.

If you want to test your email, Hipchat room and Pagerduty OPTS are correctly configured and working, do the following, once again using the Python-2.7.12 virtualenv and documentation PATHs as an example:

PYTHON_VIRTUALENV_DIR="/opt/python_virtualenv"
PROJECT="skyline-py2712"

cd "${PYTHON_VIRTUALENV_DIR}/projects/${PROJECT}"
source bin/activate
python /opt/skyline/github/skyline/utils/verify_alerts.py --trigger True --metric 'skyline_test.alerters.test'
deactivate

You should get an alert on each alerter that you have enabled. Do note that the graphs sent with the alerts will have no data in them.
