Consuming new notifications, or selecting specific topics/exchanges, should not require explicit python code additions as it does currently in ceilometer. Instead all this should be driven from a single source of configuration in an easily readable format such as YAML. To facilitate ease of upgrades, if the configuration file is missing, we should fallback to the out-of-the-box defaults in-code.
*** Bug 1258887 has been marked as a duplicate of this bug. ***
The goal of this feature is to be able to define meters as part of a declarative yaml file without having to write notification handlers. Things to verify: * Installation. Make sure the yaml file is deployed and accessible under /etc/ceilometer/meter.yaml and fallsback to ceilometer/meter/data/meter.yaml. * Verify multi meter notifications * Verify definitions which involve volume computation having an expression * Verify definitions with combination strings * Validate error handling: - syntax handling - required fields in yaml (name, event_type, volume, type) - missing config - duplicate entries - types of meters * By default, event meters with volume =1 are disabled, to enable these set store_notifications enabled and verify volume=1 meters and vice-versa. * exchange control shouldnt change much.. just moved it to a central location * Overall we need to make sure the default meters in meters.yaml are generating samples as expected. Please let me know if you need any clarification.
