-Yardstick Test Case Description TC048
-*************************************

-+-----------------------------------------------------------------------------+
-|Control Node Openstack Service High Availability - Cinder Api |
-| |
-+--------------+--------------------------------------------------------------+
-|test case id | OPNFV_YARDSTICK_TC048: Control node Openstack service down - |
-| | cinder api |
-+--------------+--------------------------------------------------------------+
-|test purpose | This test case will verify the high availability of the |
-| | volume service provided by OpenStack (cinder-api) on control |
-| | node. |
-| | |
-+--------------+--------------------------------------------------------------+
-|test method | This test case kills the processes of cinder-api 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 "cinder- |
-| | api". |
-| | 3) host: which is the name of a control node being attacked. |
-| | |
-| | e.g. |
-| | -fault_type: "kill-process" |
-| | -process_name: "cinder-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. |
-| | In this case, the command name should be cinder related |
-| | commands. |
-| | |
-| | 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: "cinder list" |
-| | monitor2: |
-| | -monitor_type: "process" |
-| | -process_name: "cinder-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 |
-| | |

-|test tool | Developed by the project. Please see folder: |
-| | "yardstick/benchmark/scenarios/availability/ha_tools" |
-| | |
-+--------------+--------------------------------------------------------------+

-| | |
-+--------------+--------------------------------------------------------------+
-|configuration | This test case needs two configuration files: |
-| | 1) test case file: opnfv_yardstick_tc048.yaml |
-| | -Attackers: see above "attackers" discription |
-| | -waiting_time: which is the time (seconds) from the process |
-| | being killed to stoping monitors the monitors |
-| | -Monitors: see above "monitors" discription |
-| | -SLA: see above "metrics" discription |
-| | |
-| | 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. |
-| | |
-+--------------+--------------------------------------------------------------+
-|test sequence | description and expected result |
-| | |
-+--------------+--------------------------------------------------------------+
-|step 1 | start monitors: |
-| | each monitor will run with independently process |
-| | |
-| | Result: The monitor info will be collected. |
-| | |
-+--------------+--------------------------------------------------------------+
-|step 2 | 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 3 | stop monitors after a period of time specified by |
-| | "waiting_time" |
-| | |
-| | Result: The monitor info will be aggregated. |
-| | |
-+--------------+--------------------------------------------------------------+
-|step 4 | verify the SLA |
-| | |
-| | Result: The test case is passed or not. |
-| | |
-+--------------+--------------------------------------------------------------+
-|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. |
