I would think Ceilometer is the right place for this. So I download and read Ceilometer a little bit. If somebody can give me a pointer to where I can start to hook my program with the notification mechanism of the ceilometer, that would be a great. Thanks and any suggestions are welcome! you can take a look at Events as well: http://docs.openstack.org/developer/ceilometer/events.html there is a translation file[1] and pipeline[2] related to it [1] https://github.com/openstack/ceilometer/blob/master/etc/ceilometer/event_definitions.yaml [2] https://github.com/openstack/ceilometer/blob/master/etc/ceilometer/event_pipeline.yaml -- gord -------------- next part -------------- An HTML attachment was scrubbed...
