本文讲述了利用jmeter来压测消息队列,其中消息队列采用apache的activemq,jmeter本身是支持符合jms标准消息队列的压测,由于jmeter的官方sampler配置比较复杂,本文直接使用sdk的方式来压测,与生产实际使用更加接近,各位如对官方的sampler感兴趣,可以自行去配置完成。
准备工作:下载activemq 地址:http://activemq.apache.org 本文中的activemq采用的是5.9.0版本。
jMetterLessons工程源码地址:https://github.com/mantuliu/jMetterLessons
1.将下载到的activemq的压缩包解压,目录中不要有中文名称,然后在 bin 目录执行activemq.bat命令,命令行输出类似于下面的界面,证明activemq启动成功:
2.访问站点:http://localhost:8161/admin 用户名:admin 密码:admin 登录成功后,activemq管理界面如下所示,目前还没有相应的队列:
3.在工程jMeterLessions下的pom文件中增加下面的依赖:
<dependency> <groupId>org.apache.geronimo.specs</groupId> <artifactId>geronimo-jms_1.1_spec</artifactId> <version>1.1</version> </dependency> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-client</artifactId> <version>5.9.0</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-nop</artifactId> <version>1.7.5</version> </dependency>
4.使用mvn eclipse:eclipse重新生成eclipse项目,命令在执行过程中自动下载相关的包
5.调用activemq的发送者类如下:
package com.mantu.jmeter; import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient; import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext; import org.apache.jmeter.samplers.SampleResult; import org.apache.activemq.ActiveMQConnectionFactory; import org.apache.activemq.command.ActiveMQQueue; import javax.jms.*; /** * blog http://www.cnblogs.com/mantu/ * * @author mantu * */ public class Lesson5 extends AbstractJavaSamplerClient{ public static void main(String [] args){ } @Override public SampleResult runTest(JavaSamplerContext arg0) { // TODO Auto-generated method stub SampleResult sr = new SampleResult(); sr.setSampleLabel("activemq测试"); try{ sr.sampleStart(); String user = env("ACTIVEMQ_USER", "admin"); String password = env("ACTIVEMQ_PASSWORD", "password"); String host = env("ACTIVEMQ_HOST", "localhost"); int port = Integer.parseInt(env("ACTIVEMQ_PORT", "61616")); String destination = "event"; int messages = 10; int size = 256; String DATA = "abcdefghijklmnopqrstuvwxyz"; String body = ""; for( int i=0; i < size; i ++) { body += DATA.charAt(i%DATA.length()); } ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("tcp://" + host + ":" + port); Connection connection = factory.createConnection(user, password); connection.start(); Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); Destination dest = new ActiveMQQueue(destination); MessageProducer producer = session.createProducer(dest); producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT); for( int i=1; i <= messages; i ++) { TextMessage msg = session.createTextMessage(body); msg.setIntProperty("id", i); producer.send(msg); if( (i % 1000) == 0) { System.out.println(String.format("Sent %d messages", i)); } } producer.send(session.createTextMessage("SHUTDOWN")); connection.close(); sr.setResponseData("success"); sr.setDataType(SampleResult.TEXT); sr.setSuccessful(true); } catch(Exception ex){ sr.setSuccessful(false); ex.printStackTrace(); } finally{ sr.sampleEnd(); } return sr; } private static String env(String key, String defaultValue) { String rc = System.getenv(key); if( rc== null ) return defaultValue; return rc; } private static String arg(String []args, int index, String defaultValue) { if( index < args.length ) return args[index]; else return defaultValue; } }
6.导出jMetterLessons工程为jar文件,输出到jmeter的lib/ext目录,并将activemq-all-5.9.0.jar(此文件可以在activemq中找到)拷贝到jmeter的lib/ext目录
7.配置java请求,并将类配置为Lesson5
启动压力测试后,可以在站点http://localhost:8161/admin发现队列已经被创建,并且队列中产生了相应的消息,本文展示了activemq队列的生产者的压力测试方法,对于消费者,原理也是大同小异的,大家可以自行模拟
