ied disk is blocked, | | | which breaks down the Openstack services on this node. Read | | | and write services should still be accessed by other | | | controller nodes, and the services on failed controller node | | | should be isolated. | +--------------+--------------------------------------------------------------+ |test method | This test case blocks the disk I/O of a specified control | | | node, then checks whether the services that need to read or | | | wirte the disk of the control node are OK with some monitor | | | tools. | +--------------+--------------------------------------------------------------+ |attackers | In this test case, an attacker called "disk-block" 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 "disk-block" in this | | | test case. | | | 2) host: which is the name of a control node being attacked. | | | e.g. | | | -fault_type: "disk-block" | | | -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 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. | | | -monitor_type: "openstack-cmd" | | | -command_name: "nova flavor-list" | | | | | | 2. the second monitor verifies the read and write function | | | by a "operation" and a "result checker". | | | the "operation" have two parameters: | | | 1) operation_type: which is used for finding the operation | | | class and related scripts. | | | 2) action_parameter: parameters for the operation. | | | the "result checker" have three parameters: | | | 1) checker_type: which is used for finding the reuslt | | | checker class and realted scripts. | | | 2) expectedValue: the expected value for the output of the | | | checker script. | | | 3) condition: whether the expected value is in the output of | | | checker script or is totally same with the output. | | | | | | In this case, the "operation" adds a flavor and the "result | | | checker" checks whether ths flavor is created. Their | | | parameters show as follows: | | | operation: | | | -operation_type: "nova-create-flavor" | | | -action_parameter: | | | flavorconfig: "test-001 test-001 100 1 1" | | | result checker: | | | -checker_type: "check-flavor" | | | -expectedValue: "test-001" | | | -condition: "in" | +--------------+--------------------------------------------------------------+ |metrics | In this test case, there is one metric: | | | 1)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_tc052.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 | do attacker: connect the host through SSH, and then execute | | | the block disk I/O script on the host. | | | | | | Result: The disk I/O of the host will be blocked | | | | +--------------+--------------------------------------------------------------+ |step 2 | start monitors: | | | each monitor will run with independently process | | | | | | Result: The monitor info will be collected. | | | | +--------------+--------------------------------------------------------------+ |step 3 | do operation: add a flavor | | | | +--------------+--------------------------------------------------------------+ |step 4 | do result checker: check whether the falvor is created | | | | +--------------+--------------------------------------------------------------+ |step 5 | stop monitors after a period of time specified by | | | "waiting_time" | | | | | | Result: The monitor info will be aggregated. | | | | +--------------+--------------------------------------------------------------+ |step 6 | verify the SLA | | | | | | Result: The test case is passed or not. | | | | +--------------+--------------------------------------------------------------+ |post-action | It is the action when the test cases exist. It excutes the | | | release disk I/O script to release the blocked I/O. | +--------------+--------------------------------------------------------------+ |test verdict | Fails if monnitor SLA is not passed or the result checker is | | | not passed, or if there is a test case execution problem. | | | | +--------------+--------------------------------------------------------------+
