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" | +| | | ++--------------+--------------------------------------------------------------+ +|references | ETSI NFV REL001 | +| | | ++--------------+--------------------------------------------------------------+ +|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. | +| | | ++--------------+--------------------------------------------------------------+ |
