+|                                                                             |

+|test case id  | OPNFV_YARDSTICK_TC019_HA: Control node Openstack service down|
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|test purpose  | This test case will verify the high availability of the      |
+|              | service provided by OpenStack (like nova-api, neutro-server) |
+|              | on control node.                                             |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|test method   | This test case kills the processes of a specific Openstack   |
+|              | service on a selected control node, then checks whether the  |
+|              | request of the related Openstack command is OK and the killed|
+|              | processes are recovered.                                     |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|attackers     | In this test case, an attacker called "kill-process" is      |
+|              | needed. This attacker includes three parameters:             |
+|              | 1) fault_type: which is used for finding the attacker's      |
+|              | scripts. It should be always set to "kill-process" in this   |
+|              | test case.                                                   |
+|              | 2) process_name: which is the process name of the specified  |
+|              | OpenStack service. If there are multiple processes use the   |
+|              | same name on the host, all of them are killed by this        |
+|              | attacker.                                                    |
+|              | 3) host: which is the name of a control node being attacked. |
+|              |                                                              |
+|              | e.g.                                                         |
+|              | -fault_type: "kill-process"                                  |
+|              | -process_name: "nova-api"                                    |
+|              | -host: node1                                                 |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|monitors      | In this test case, two kinds of monitor are needed:          |
+|              | 1. the "openstack-cmd" monitor constantly request a specific |
+|              |    Openstack command, which needs two parameters:            |
+|              | 1) monitor_type: which is used for finding the monitor class |
+|              | and related scritps. It should be always set to              |
+|              | "openstack-cmd" for this monitor.                            |
+|              | 2) command_name: which is the command name used for request  |
+|              |                                                              |
+|              | 2. the "process" monitor check whether a process is running  |
+|              |    on a specific node, which needs three parameters:         |
+|              | 1) monitor_type: which used for finding the monitor class and|
+|              | related scritps. It should be always set to "process"        |
+|              | for this monitor.                                            |
+|              | 2) process_name: which is the process name for monitor       |
+|              | 3) host: which is the name of the node runing the process    |
+|              |                                                              |
+|              | e.g.                                                         |
+|              | monitor1:                                                    |
+|              | -monitor_type: "openstack-cmd"                               |
+|              | -command_name: "nova image-list"                             |
+|              | monitor2:                                                    |
+|              | -monitor_type: "process"                                     |
+|              | -process_name: "nova-api"                                    |
+|              | -host: node1                                                 |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|metrics       | In this test case, there are two metrics:                    |
+|              | 1)service_outage_time: which indicates the maximum outage    |
+|              | time (seconds) of the specified Openstack command request.   |
+|              | 2)process_recover_time: which indicates the maximun time     |
+|              | (seconds) from the process being killed to recovered         |
+|              |                                                              |

++--------------+--------------------------------------------------------------+
+|post-action   | It is the action when the test cases exist. It will check the|
