我发现一些下属的 charms 比如 ceilometer-agent 和 neutron-openvswitch 不起作用。juju deploy ceilometer-agent 和 juju add-relation ceilometer-agent ceilometer 都返回成功。然后 juju status 只显示 ceilometer-agent 处于等待状态，并且从未将其自身附加到连接的 ceilometer 单元。neutron-openvswitch 也发生了同样的事情。我尝试了 ntp，它工作正常。有人能帮忙吗？
我的 juju 状态为正在跟踪。而 ceilometer-agent 卡在等待状态，没有单元。
