Here is a description of the components planed for the JMS sampler.
- JMS publish sampler
- JMS subscribe sampler
- Sample aggregator
- Graph to display publish, subscribe and total in terms of kb/sec
- generic client class to encapsulate a JMS client
The two samplers will have common properties, which users must provide.
- URL - Context.PROVIDER_URL
- Initial context - Context.INITIAL_CONTEXT_FACTORY
- ConnectionFactory - server specific setting
- Topic - the specific topic for the test
- Iterations - number of iterations to aggregate
- Message type - TextMessage, ObjectMessage
- Use as monitor - this is similar to HTTPSampler for Tomcat5. when it is checked, the sample is set as monitor result, which is then used by the monitor to display the health and performance
The sample Aggregator is needed to aggregate several samples together, since a single publish will probably less than 1 millisecond, it's a good idea to run X iterations and record the time.
