rally性能测试简单使用

1.下载安装

apt-get install  build-essential

wget -q -O-  | bash

rally-manage db recreate

2.部署环境
$ source openrc $ rally deployment create --fromenv --name=existing
或者
rally deployment create --filename
$rally deployment check

	

		3.执行json

rally task start samples/tasks/scenarios/nova/boot-and-delete.json







rally 新测试用例开发(以rename为例)

boot-and-rename.json文件



{% set flavor_name = flavor_name or "m1.small" %}
		

			{
		
		

			   "NovaServers.boot_and_rename_changepwd":

			代码流程调用过程
		
		

			json→server.py→utils.py→docker 里面的openstack nova-clients→控制节点openstack api
		
		

			

				 
			
			

				clinet路径：vim /usr/lib/python2.7/site-packages/novaclient/v2/servers.py
			
			

				里面有两个类class Server 和class ServerManager    
			
			

				


			
			

				如果是新增功能 要在docker里面添加对应client的方法，注意不要不要放错类，同名不可能在同一类。
			
		


		

			   @types.set(image=types.ImageResourceType,//rally验证输入参数的准确性，flavor和镜像是否匹配
		
		

			               flavor=types.FlavorResourceType)
		
		

			    @validation.image_valid_on_flavor("flavor", "image")
		
		

			    @validation.required_services(consts.Service.NOVA)
		
		

			    @validation.required_openstack(users=True)
		
		

			    @scenario.configure(context={"cleanup": ["nova"]})
		




		

			servers.py
		
		

			------
		
		

			def boot_and_rename(self, image, flavor,to_name,**kwargs)://定义一个方法
		
		

			        server = self._boot_server(image, flavor, **kwargs)   //调用boot-server创建一个server对象（类实例）。
		
		

			        LOG.info("[BCEC] create server OK")   //输出日志
		
		

			        time.sleep(30)  //加30s是为了防止虚拟起来后等待qemu-guset-agent起来
		
		

			#        print (to_name,server)//自己验证的
		
		

			        self._rename_server(server,to_name)    //调用utils.py的函数
		
		

			        LOG.info("[BCEC] rename OK")
		
		

			        self._delete_server(server)
		
		

			        LOG.info("[BCEC] delete OK")
		
		

			

		
		

			@atomic.action_timer("nova.rename_server")//统计执行的时间输出在报告表格中
		
		

			def _rename_server(self, server, name):
		
		

			        print(name)
		
		

			        server.update(name['name'])     //server在_boot-server函数中已经调用过clients，所以有server的所有属性和方法
		
		

			能够直接调用update方法，还有一种是直接调用clients，一般都是get。
		
		

			

		
		

			具体的信息要看各个openstack python-novaclient的源码servers.py定义了哪些方法，如何使用参数。
