The neutron agent-list show below. DHCP and L3 is not in alive status

+--------------------+--------------+-------------------+-------+----------------+
| agent_type         | host         | availability_zone | alive | admin_state_up |
+--------------------+--------------+-------------------+-------+----------------+
| DHCP agent         | controller01 | nova              | xxx   | True           |
| L3 agent           | controller01 | nova              | xxx   | True           |

Also in neutron server log:

            L3 agent  2016-07-13 07:59:55 controller01

Seems L3 and DHCP is having some problem. But I can see the process of these two service. Also there is no error in DHCP agent log and L3 agent log

Logs of l3 agent showing it is started
