| Doc Text: |
Previously, when a ceilometer polling extension could not be loaded, an ERROR message was logged. This was misleading in cases where the failure to load a module was the expected outcome, such as when an extension was optional or its dependent modules were not available. Now, the log messages have been changed to WARN level to make it clear that there is no serious fault.

There are basically two things going on here, neither of which is ideal, but both of which are expected behaviors: * The rgw support is configured as a polling extension in ceilometer's entry_points. When the polling agent starts up it will attempt to import the extension. If awsauth is not available in the python environment this will fail and the extension will not be used for the duration of the polling agent's life. This is expected behavior for optional extensions. It is, however, a bit weird: We configure entry_points that are optional and we know will fail. * When that import failure happens, the exception is logged as ERROR which seems a bit severe for something that we expect to happen. WARNING might make more sense. Short term options: * Accept the ERROR as normal and ignore it. * Include awsauth so that the rgw code can import. This might have some knock on effects: The rgw extension will try to run and may produce further warnings about resources not being available. Medium term options: * Consider registering an upstream bug that the ERROR should be a WARN Longer term options: * Change how polling agents configure their extensions so they only load the things they actually use. This is unlikely to be visible any time soon.
