When a | +| | controller node , which holds all active application | +| | resources, failed to communicate with other cluster nodes | +| | (via corosync), the test case will check whether the standby | +| | application resources will take place of those active | +| | application resources which should be regarded to be down in | +| | the cluster manager. | ++--------------+--------------------------------------------------------------+ +|test method | This test case kills the processes of cluster messaging | +| | service(corosync) on a selected controller node(the node | +| | holds the active application resources), then checks whether | +| | active application resources are switched to other | +| | controller nodes and whether the Openstack commands are OK. | ++--------------+--------------------------------------------------------------+ +|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 load | +| | balance service. If there are multiple processes use the | +| | same name on the host, all of them are killed by this | +| | attacker. | +| | 3) host: which is the name of a control node being attacked. | +| | | +| | In this case, this process name should set to "corosync" , | +| | for example | +| | -fault_type: "kill-process" | +| | -process_name: "corosync" | +| | -host: node1 | ++--------------+--------------------------------------------------------------+ +|monitors | In this test case, a kind of monitor is 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 scripts. 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 of monitor1 should be services| +| | that are managed by the cluster manager. (Since rabbitmq and | +| | haproxy are managed by pacemaker, most Openstack Services | +| | can be used to check high availability in this case) | +| | | +| | (e.g.) | +| | monitor1: | +| | -monitor_type: "openstack-cmd" | +| | -command_name: "nova image-list" | +| | monitor2: | +| | -monitor_type: "openstack-cmd" | +| | -command_name: "neutron router-list" | +| | monitor3: | +| | -monitor_type: "openstack-cmd" | +| | -command_name: "heat stack-list" | +| | monitor4: | +| | -monitor_type: "openstack-cmd" | +| | -command_name: "cinder list" | +| | | ++--------------+--------------------------------------------------------------+ +|checkers | In this test case, a checker is needed, the checker will | +| | the status of application resources in pacemaker and the | +| | checker have three parameters: | +| | 1) checker_type: which is used for finding the result | +| | checker class and related scripts. In this case the checker | +| | type will be "pacemaker-check-resource" | +| | 2) resource_name: the application resource name | +| | 3) resource_status: the expected status of the resource | +| | 4) expectedValue: the expected value for the output of the | +| | checker script, in the case the expected value will be the | +| | identifier in the cluster manager | +| | 3) condition: whether the expected value is in the output of | +| | checker script or is totally same with the output. | +| | (note: pcs is required to installed on controller node in | +| | order to run this checker) | +| | | +| | (e.g.) | +| | checker1: | +| | -checker_type: "pacemaker-check-resource" | +| | -resource_name: "p_rabbitmq-server" | +| | -resource_status: "Stopped" | +| | -expectedValue: "node-1" | +| | -condition: "in" | +| | checker2: | +| | -checker_type: "pacemaker-check-resource" | +| | -resource_name: "p_rabbitmq-server" | +| | -resource_status: "Master" | +| | -expectedValue: "node-2" | +| | -condition: "in" | ++--------------+--------------------------------------------------------------+ +|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. | ++--------------+--------------------------------------------------------------+ +|test tool | None. Self-developed. | ++--------------+--------------------------------------------------------------+ +|references | ETSI NFV REL001 | ++--------------+--------------------------------------------------------------+ +|configuration | This test case needs two configuration files: | +| | 1) test case file: opnfv_yardstick_tc057.yaml | +| | -Attackers: see above "attackers" description | +| | -Monitors: see above "monitors" description | +| | -Checkers: see above "checkers" description | +| | -Steps: the test case execution step, see "test sequence" | +| | description below | +| | | +| | 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 | do checker: check whether the status of application | +| | resources on different nodes are updated | +| | | ++--------------+--------------------------------------------------------------+ +|step 4 | stop monitors after a period of time specified by | +| | "waiting_time" | +| | | +| | Result: The monitor info will be aggregated. | +| | | ++--------------+--------------------------------------------------------------+ +|step 5 | verify the SLA | +| | | +| | Result: The test case is passed or not. | +| | | ++--------------+------+----------------------------------+--------------------+ +|post-action | It is the action when the test cases exist.
