how to load testing using jmeter

}",//body of the content ,// the length of the body content of the line aboveraw_body_end,// The identifier of the request body endlast);return 0;}Method for calculating the length of the body content: Install the Firebug plugin in Firefox. Open Firefox, then open the console In the console, enter the body content, and then use the Length property to get the string, if for the above example, it is | | "{\" userids\ ": [1300000001,1300002029,1300003163],\" type\ ": 0}". length |

In the previous article using JMeter to construct a large number of concurrent HTTP requests for microservices performance testing, I described how to construct concurrent HTTP requests with JMeter. However, the request parameters of the concurrent request constructed by the method described in the article are hard-cod

When using Jemeter to do stress testing, it is often necessary to parameterize the user name, password to reach multiple users using a different user name password to login. At this point we can use the CSV Data Set config to implement parameterized logins:First, the test plan or thread group's add->config element->csv Data Set Config is addedThe following is a b

information on stress testing, an analogy to explain the difference between CPU utilization and load average and the implications for stress testing? We'll analogy the CPU to a phone booth, and each process is a person who needs to call. There are now 4 telephone booths (just like our machines have 4 cores) and 10 people need to call. The rule for

testing, but it has been extended to support a variety of Test Modules. It is shipped together with modules used for HTTP and SQL databases (using JDBC. It can be used to test the running status of servers in static databases or active databases, and can be used to simulate heavy loads on servers or network systems to test their resistance, it can also be used to analyze all running conditions of different

This article describes how to use JMeter to test the database, the case of MySQL as a testing database, the other database is the same, only need to replace the driver.Preparation: A.mysql database installation, please self-Baidu; B.JDBC driver Pack, download files on my github Log4jdbc4-1.2beta2.jar , Mysql-connector-java-5.1.21.jar : Https://github.com/mantuliu/publiclibs1. First copy the Log4jdbc4-1.2be

, "If it is free, it is mine ." In addition to its price advantages, this tool also provides complete functions and is continuously being upgraded and updated. Microsoft.com is often used, so they will understand the importance of this tool. But you don't need to talk too much about me, just try it on your own. I will provide a list at the end of the article to list some third-party stress testing tools. You can decide what tools to choose. The bottom

Reprinted from: http://www.blogjava.net/cenwenchu/archive/2008/06/30/211712.htmlSIP 's fourth phase is over because of the richness of the control strategy, the previous stress test results have been unable to reflect the health of the SIP at high concurrency and high pressure , and therefore need to be re-tested for stress. After the test staff to do a week of stress testing, the pressure test report is formally released, it is also an end, but the n

Post: Unknown SourceHow many concurrent user accesses can your Web servers and Applications Support? Is the software faulty when a large number of concurrent requests occur? These questions cannot be answered by common testing methods. This article introduces Microsoft's free tool WAS for this purpose and its usage. In addition, this article introduces a Web application performance optimization method, and uses WAS to test its performance improvement

Analysis resultsC, the pressure test6 Configuring online MonitoringOnce you have a stable server configuration, you can put your system into production and continue to use WMLS for online monitoring. You can configure a two-day client, one to connect to a server on a local area network, and one to connect to the server via the Internet. Such as:The purpose of

Using LoadRunner for load testing in large loads requires configuring some environment to meet the full range of resources under heavy load:1. In order to avoid the occurrence of "No Buffer Space Available "Error, the following configuration is required:1) Modify the registration form:* Set "Hkey_local_machine\system\c
