[esb-issues] [JBoss JIRA] Work stopped: (JBESB-1105) ESB Should have a good load generation framework

ESB Should have a good load generation framework ------------------------------------------------ Key: JBESB-1105 URL: http://jira.jboss.com/jira/browse/JBESB-1105 Project: JBoss ESB Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Testing, Examples Environment: I have created groovy scripts that simulate load and provide some TPS metrics. I used an external Groovy 1.1-Beta as my test for these scripts. Groovy is bootstrapped in the build script, so it's possible to swap it out with the ESB bundled, but I do not know if I'm doing any 1.1 specific stuff. Reporter: James Williams Assigned To: Mark Little Priority: Minor Original Estimate: 2 days Remaining Estimate: 2 days There are 2 groovy scripts. One script, JMSLoadAgent.groovy, simulates load by dropping sample messages into a JMS gateway. There are a slew of properties entries to control the throttling of messages, and the payload file can be specified outside of the groovy script. This script is designed to be a template for other load scripts. For example, a load script that drops files into a directory that has a file system listener. The 2nd script, LoadReport.groovy, uses the JMX MBean stats at the service level to report TPS. you can specify one or more services as a comma separated list. And, there is a short circuit that will kill the reporter. The short cut is a bit crude, but it works. You specify the fastest ESB listener queue. When that queue depth is at 0, the report stops. The report will print out to the console, and to a properties file configured location. There are also several ant targets to run either the agent, reporter or both. I also include a sample ESB archive to test the quickstart and the services are hardwired so that one is distinctively faster than the other. These scripts should work for any service, provided the user adds the proper entries to "load.properties". There is no GUI for this yet, but I started out with a GUI, then realized that primary benefit of the load framework is the stats dumped into a log file or on the console. All other stuff is pretty straightforward with a simple properties file. The readme.txt probably needs a little beef, but I'm going to go ahead and check this in because I think it's going to be a very valuable contribution for users looking to load test and identify TPS at the service level.
