The main idea of the proposal is to implement a plugin to integrate external monitors for more monitoring information such as application-level metrics. Some people use Ganglia or Sensu to monitor the cloud since these monitors can get application-level metric records, such as database usage. If Ceilometer provides plugins for these monitors, users are more likely to use Ceilometer as it is easy to install in Openstack. And the ability of Ceilometer monitoring can be enhanced.","commit_id":"3bb3289079ab7b2bfc95ce09a039032553bef1ae"},{"author":{"_account_id":8290,"name":"liusheng","email":"liusheng2048@gmail.com","username":"LiuSheng"},"change_message_id":"1ace74669c85bb1777b83d5a25898c6ac31122c7","unresolved":false,"context_lines":[{"line_number":21,"context_line":""},{"line_number":22,"context_line":"Ceilometer monitoring metrics have some restrictions in function and"},{"line_number":23,"context_line":"performance.
