* High level description:

I suggest that updating the status of the agent upon detecting error
logs.

I understand that "neutron agent-list " output means only whether the agent is running.
However, by changing the display if the agent is not working properly, it helps to troubleshoot.


* Pre-conditions:

It will occur in an environment that br-ex does not exist. (This is an
example.)


* Step-by-step reproduction steps:

1. Build the environment with the Devstack.
2. Remove the br-ex.
3. Boot the instance.
4. The Instance booting will fail.


* Expected output:

When the agent is not working properly, chang the display as follows:

$ neutron agent-list -c agent_type -c alive
+--------------------+-------+
| agent_type | alive |
+--------------------+-------+
| L3 agent | :-) |
| Open vSwitch agent | :-( |
| DHCP agent | :-) |
+--------------------+-------+
...


* Actual output:

q-agt.log
http://paste.openstack.org/show/493429/


$ neutron agent-list -c agent_type -c alive
+--------------------+-------+
| agent_type | alive |
+--------------------+-------+
| L3 agent | :-) |
| Open vSwitch agent | :-) |
| DHCP agent | :-) |
+--------------------+-------+
