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. | | | | | | Notice: This post-action uses 'lsb_release' command to check | | | the host linux distribution and determine the OpenStack | | | service name to restart the process. Lack of 'lsb_release' | | | on the host may cause failure to restart the process. | | | | +--------------+------+----------------------------------+--------------------+ |test verdict | Fails only if SLA is not passed, or if there is a test case | | | execution problem. | | | | +--------------+--------------------------------------------------------------+
