++-----------------------------------------------------------------------------+
+|Control Node Openstack Service High Availability - Nova Scheduler            |
+|                                                                             |

+|test case id  | OPNFV_YARDSTICK_TC088: Control node Openstack service down - |
+|              | nova scheduler                                               |
++--------------+--------------------------------------------------------------+
+|test purpose  | This test case will verify the high availability of the      |
+|              | compute scheduler service provided by OpenStack (nova-       |
+|              | scheduler) on control node.                                  |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|test method   | This test case kills the processes of nova-scheduler 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.                                                    |
+|              | In this case. This parameter should always set to "nova-     |
+|              | scheduler".                                                  |
+|              | 3) host: which is the name of a control node being attacked. |
+|              |                                                              |
+|              | e.g.                                                         |
+|              | -fault_type: "kill-process"                                  |
+|              | -process_name: "nova-scheduler"                              |
+|              | -host: node1                                                 |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|monitors      | In this test case, one kind of monitor is needed:            |
+|              | 1. 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 scripts. 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 running the process   |
+|              |                                                              |
+|              | e.g.                                                         |
+|              | monitor:                                                     |
+|              | -monitor_type: "process"                                     |
+|              | -process_name: "nova-scheduler"                              |
+|              | -host: node1                                                 |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|operations    | In this test case, the following operations are needed:      |
+|              | 1. "nova-create-instance": create a VM instance to check     |
+|              | whether the nova-scheduler works normally.                   |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|metrics       | In this test case, there are one metric:                     |
+|              | 1)process_recover_time: which indicates the maximum time     |
+|              | (seconds) from the process being killed to recovered         |
+|              |                                                              |

+|configuration | This test case needs two configuration files:                |
+|              | 1) test case file: opnfv_yardstick_tc088.yaml                |
+|              | -Attackers: see above "attackers" description                |
+|              | -waiting_time: which is the time (seconds) from the process  |
+|              | being killed to stopping monitors the monitors               |
+|              | -Monitors: see above "monitors" description                  |

+|              |                                                              |
+|              | 2)POD file: pod.yaml                                         |
+|              | The POD configuration should record on pod.yaml first.       |
+|              | the "host" item in this test case will use the node name in  |
+|              | the pod.yaml.                                                |
+|              |                                                              |

+|step 1        | do attacker: connect the host through SSH, and then execute  |
+|              | the kill process script with param value specified by        |
+|              | "process_name"                                               |

+|              | Result: Process will be killed.                              |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|step 2        | start monitors:                                              |
+|              | each monitor will run with independently process             |
+|              |                                                              |
+|              | Result: The monitor info will be collected.                  |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|step 3        | create a new instance to check whether the nova scheduler    |
+|              | works normally.                                              |
+|              |                                                              |

++--------------+--------------------------------------------------------------+
+|post-action   | It is the action when the test cases exist. It will check the|
+|              | status of the specified process on the host, and restart the |
+|              | process if it is not running for next test cases             |
+|              |                                                              |
++--------------+--------------------------------------------------------------+
+|test verdict  | Fails only if SLA is not passed, or if there is a test case  |
+|              | execution problem.                                           |
