+Yardstick Test Case Description TC054
+*************************************
+
++-----------------------------------------------------------------------------+
+|OpenStack Virtual IP High Availability |
+| |
++--------------+--------------------------------------------------------------+
+|test case id | OPNFV_YARDSTICK_TC054: OpenStack Virtual IP High |
+| | Availability |
++--------------+--------------------------------------------------------------+
+|test purpose | This test case will verify the high availability for virtual |
+| | ip in the environment. When master node of virtual ip is |
+| | abnormally shutdown, connection to virtual ip and |
+| | the services binded to the virtual IP it should be OK. |
++--------------+--------------------------------------------------------------+
+|test method | This test case shutdowns the virtual IP master node with |
+| | some fault injection tools, then checks whether virtual ips |
+| | can be pinged and services binded to virtual ip are OK with |
+| | some monitor tools. |
++--------------+--------------------------------------------------------------+
+|attackers | In this test case, an attacker called "control-shutdown" is |
+| | needed. This attacker includes two parameters: |
+| | 1) fault_type: which is used for finding the attacker's |
+| | scripts. It should be always set to "control-shutdown" in |
+| | this test case. |
+| | 2) host: which is the name of a control node being attacked. |
+| | |
+| | In this case the host should be the virtual ip master node, |
+| | that means the host ip is the virtual ip, for exapmle: |
+| | -fault_type: "control-shutdown" |
+| | -host: node1(the VIP Master node) |
++--------------+--------------------------------------------------------------+
+|monitors | In this test case, two kinds of monitor are needed: |
+| | 1. the "ip_status" monitor that pings a specific ip to check |
+| | the connectivity of this ip, which needs two parameters: |
+| | 1) monitor_type: which is used for finding the monitor class |
+| | and related scripts. It should be always set to "ip_status" |
+| | for this monitor. |
+| | 2) ip_address: The ip to be pinged. In this case, ip_address |
+| | should be the virtual IP. |
+| | |
+| | 2. 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 scripts. It should be always set to |
+| | "openstack-cmd" for this monitor. |
+| | 2) command_name: which is the command name used for request. |
+| | |
+| | e.g. |
+| | monitor1: |
+| | -monitor_type: "ip_status" |
+| | -host: 192.168.0.2 |
+| | monitor2: |
+| | -monitor_type: "openstack-cmd" |
+| | -command_name: "nova image-list" |
+| | |
++--------------+--------------------------------------------------------------+
+|metrics | In this test case, there are two metrics: |
+| | 1) ping_outage_time: which-indicates the maximum outage time |
+| | to ping the specified host. |
+| | 2)service_outage_time: which indicates the maximum outage |
+| | time (seconds) of the specified Openstack command request. |
++--------------+--------------------------------------------------------------+
+|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_tc054.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 shutdown script on the VIP master node. |
+| | |
+| | Result: VIP master node will be shutdown |
+| | |
++--------------+--------------------------------------------------------------+
+|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 restarts the |
+| | original VIP master node if it is not restarted. |
+| | |
++--------------+--------------------------------------------------------------+
+|test verdict | Fails only if SLA is not passed, or if there is a test case |
+| | execution problem. |
+| | |
