IIUC, the commit https://github.com/openstack/ceilometer/commit/b65554eb460a282a2ab0a2dcc0053a8691cb9373 results in the warning messages when the polled neutron services are disabled.., do we want to not log the warnings and return silently?

[Liusheng (liusheng)]

maybe change the LOG.warn(e) to a short log hint is better, don't need to record the whole exception.

[gordon chung (chungg)]

yeah, i think it'd be better to hide the full error since it's expected.

    Fix for resource polling warnings

    When neutron services are disabled,
    neutron client logs the 404 exception
    at warn level, this exception log
    is unwanted and it suffices to log
    just the error message.
