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. | +| | 3) host: which is the name of a control node being attacked. | +| | | +| | e.g. | +| | -fault_type: "kill-process" | +| | -process_name: "nova-api" | +| | -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 scritps. It should be always set to | +| | "openstack-cmd" for this monitor. | +| | 2) command_name: which is the command name used for request | +| | | +| | 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 scritps. 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 runing the process | +| | | +| | e.g. | +| | monitor1: | +| | -monitor_type: "openstack-cmd" | +| | -command_name: "nova image-list" | +| | monitor2: | +| | -monitor_type: "process" | +| | -process_name: "nova-api" | +| | -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 maximun time | +| | (seconds) from the process being killed to recovered | +| | | ++--------------+--------------------------------------------------------------+ +|test tool | Developed by the project.
