When a virtual router | +| | service on a specified controller node is shut down, this | +| | test case will check whether the network of virtual machines | +| | will be affected, and whether the attacked virtual router | +| | service will be recovered. | ++--------------+--------------------------------------------------------------+ +|test method | This test case kills the processes of virtual router service | +| | (l3-agent) on a selected controller node(the node holds the | +| | active l3-agent), then checks whether the network routing | +| | of virtual machines is OK and whether the killed service | +| | will be 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 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 "l3agent" , | +| | for example | +| | -fault_type: "kill-process" | +| | -process_name: "l3agent" | +| | -host: node1 | ++--------------+--------------------------------------------------------------+ +|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 | +| | will be either an ip address of external network or an ip | +| | address of a virtual machine. | +| | 3) host: The node on which ping will be executed, in this | +| | case the host will be a virtual machine. | +| | | +| | 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. In | +| | this case, the process-name of monitor2 should be "l3agent" | +| | 3) host: which is the name of the node running the process | +| | | +| | e.g. | +| | monitor1-1: | +| | -monitor_type: "ip_status" | +| | -host: 172.16.0.11 | +| | -ip_address: 172.16.1.11 | +| | monitor1-2: | +| | -monitor_type: "ip_status" | +| | -host: 172.16.0.11 | +| | -ip_address: 8.8.8.8 | +| | monitor2: | +| | -monitor_type: "process" | +| | -process_name: "l3agent" | +| | -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 maximum time | +| | (seconds) from the process being killed to recovered | ++--------------+--------------------------------------------------------------+ +|test tool | None. Self-developed. | ++--------------+--------------------------------------------------------------+ +|references | ETSI NFV REL001 | ++--------------+--------------------------------------------------------------+ +|configuration | This test case needs two configuration files: | +| | 1) test case file: opnfv_yardstick_tc058.yaml | +| | -Attackers: see above "attackers" description | +| | -Monitors: see above "monitors" 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 | +| | | ++--------------+--------------------------------------------------------------+ +|pre-test | The test case image needs to be installed into Glance | +|conditions | with cachestat included in the image. | +| | | ++--------------+--------------------------------------------------------------+ +|step 1 | Two host VMs are booted, these two hosts are in two different| +| | networks, the networks are connected by a virtual router | +| | | ++--------------+--------------------------------------------------------------+ +|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 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. 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. | +| | Virtual machines and network created in the test case will | +| | be destoryed. | +| | | ++--------------+------+----------------------------------+--------------------+ +|test verdict | Fails only if SLA is not passed, or if there is a test case | +| | execution problem. | ++--------------+--------------------------------------------------------------+ -- cgit 1.2.3-korg
