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 "neutron- | | | server". | | | 3) host: which is the name of a control node being attacked. | | | | | | e.g. | | | -fault_type: "kill-process" | | | -process_name: "neutron-server" | | | -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. | | | In this case, the command name should be neutron related | | | commands. | | | | | | 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: "neutron agent-list" | | | monitor2: | | | -monitor_type: "process" | | | -process_name: "neutron-server" | | | -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 recovere<style>.highlight .hll { background-color: #ffffcc } .highlight .c { color: #888888 } /* Comment */ .highlight .err { color: #a61717;
