This charm was developed to support deploying Folsom on both Ubuntu Quantal |
13 |
and Ubuntu Precise. Since Ceilometer is only available for Ubuntu 12.04 via |
|
14 |
the Ubuntu Cloud Archive, deploying this charm to a Precise machine will by |
|
15 |
default install Ceilometer and its dependencies from the Cloud Archive. |
