openstack-kilo-neutron-agent服务实际是active的-但是显示为XXX

重启后出现了这样的情况：

查看详细的参数

查看数据库neutron 中对应的agents表。发现表中没有alive这个字段

也不知道该从哪下手找问题点了，还请知道的或者遇到过这个问题的朋友指点一下。感谢！！！

active为false。具体楼主看下/var/log/neutron的日志
服务应该是不正常的

补充一下：
这些服务的实际状态为active：

在compute node中做了关闭一个服务 再开启一个服务  查看log  
发现log中有这样的提示 ：

再补充一下：
在compute node中做了关闭一个服务 再开启一个服务  查看log  
发现log中有这样的提示 ：

----google了一下----
that when the agents first boot up, they are out of sync. And that's normal behaviour. Then they do synchronize, but no message is written back in the logs,
当重启agent的时候如果提示下面的是正确的举动：
Agent tunnel out of sync with plugin!
Agent out of sync with plugin!





--------google到一个可能的解决方案点-------
也就是说agents会固定一段时间（75s）去向neutron-server报告，如果neutron-server没有收到agents们的报告就会显示为XXX。从这个点出发，建议查看schedule task
Agents report their own status to neutron-server periodically. The default inter time is 75 seconds. If neutron server can't recieve the report in 75 secods,the alive of the agent will be xxx. And it will be changed to :-) after recieving new status report.
Translates into : If this happens all of the time and is causing issues with scheduling then you should look into load on the servers where the agents are running, look into the logs of the agents, see if there are any issues with scheduled tasks

是有点奇怪。
查看下其他日志，需要找到error。对于这种假死的状态，重启应该就好了

----在log中发现了一些问题，似乎是因为没有qdhcp的namespace---
2016-06-23 15:21:39.505 2876 INFO os ...

此问题已经resolved。
原因：
各个node间的时间不同步导致了各个agent不能正常的运行
[解决方案]
troubleshooting ntp or chrony to sync time with different node
1.在controller0上建立timeServer   network and compute sync controller0

2.restart neutron agents on network node

3.restart nova-compute service on compute node

4.check neutron mult-agent service on network node
