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 "nova- | +| | scheduler". | +| | 3) host: which is the name of a control node being attacked. | +| | | +| | e.g. | +| | -fault_type: "kill-process" | +| | -process_name: "nova-scheduler" | +| | -host: node1 | +| | | ++--------------+--------------------------------------------------------------+ +|monitors | In this test case, one kind of monitor is needed: | +| | 1. 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 running the process | +| | | +| | e.g. | +| | monitor: | +| | -monitor_type: "process" | +| | -process_name: "nova-scheduler" | +| | -host: node1 | +| | | ++--------------+--------------------------------------------------------------+ +|operations | In this test case, the following operations are needed: | +| | 1. "nova-create-instance": create a VM instance to check | +| | whether the nova-scheduler works normally. | +| | | ++--------------+--------------------------------------------------------------+ +|metrics | In this test case, there are one metric: | +| | 1)process_recover_time: which indicates the maximum 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_tc088.yaml | +| | -Attackers: see above "attackers" description | +| | -waiting_time: which is the time (seconds) from the process | +| | being killed to stopping monitors the monitors | +| | -Monitors: see above "monitors" description | +| | -SLA: see above "metrics" description | +| | | +| | 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 kill process script with param value specified by | +| | "process_name" | +| | | +| | Result: Process will be killed. | +| | | ++--------------+--------------------------------------------------------------+ +|step 2 | start monitors: | +| | each monitor will run with independently process | +| | | +| | Result: The monitor info will be collected. | +| | | ++--------------+--------------------------------------------------------------+ +|step 3 | create a new instance to check whether the nova scheduler | +| | works normally. | +| | | ++--------------+--------------------------------------------------------------+ +|step 4 | stop the monitor after a period of time specified by | +| | "waiting_time" | +| | | +| | Result: The monitor info will be aggregated. | +| | | ++--------------+--------------------------------------------------------------+ +|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. | +| | | ++--------------+--------------------------------------------------------------+ |
