When the load balance service | +| | of a specified controller node is killed, whether other load | +| | balancers on other controller nodes will work, and whether | +| | the controller node will restart the load balancer are | +| | checked. | ++--------------+--------------------------------------------------------------+ +|test method | This test case kills the processes of load balance 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 "swift- | +| | proxy". | +| | 3) host: which is the name of a control node being attacked. | +| | | +| | e.g. | +| | -fault_type: "kill-process" | +| | -process_name: "haproxy" | +| | -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 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 runing the process | +| | In this case, the command_name of monitor1 should be | +| | services that is supported by load balancer and the process- | +| | name of monitor2 should be "haproxy", for example: | +| | | +| | e.g. | +| | monitor1: | +| | -monitor_type: "openstack-cmd" | +| | -command_name: "nova image-list" | +| | monitor2: | +| | -monitor_type: "process" | +| | -process_name: "haproxy" | +| | -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" | +| | | ++--------------+--------------------------------------------------------------+ +|references | ETSI NFV REL001 | +| | | ++--------------+--------------------------------------------------------------+ +|configuration | This test case needs two configuration files: | +| | 1) test case file: opnfv_yardstick_tc053.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. | +| | | ++--------------+--------------------------------------------------------------+ -- cgit
