How to set the test environment?
1. In this demo, the idea is based on Aodh's event alarm, so it needs to be enabled in ceilometer, see http://docs.openstack.org/developer/aodh/event-alarm.html
The key part is add this line:
- notifier://?topic=alarm.all
to /etc/ceilometer/event_pipeline.yaml
2. We're using Zaqar's websocket and wsgi transports, so they need to be enabled both. Luckily, it's default in devstack.
- Running the websocket.html under your apache server
2. Disable the CORS of your browser. And please use Firefox with cors injector addon. See /~https://github.com/fredericlb/Force-CORS/releases
- After enabled the cors injector, please use below value for its "Headers to inject" config:
Access-Control-Allow-Origin *|Access-Control-Allow-Methods POST,GET|Access-Control-Expose-Headers X-Subject-Token,Vary
