org.apache.jmeter.protocol.http.sampler.AccessLogSampler
Description:

AccessLogSampler is responsible for a couple of things:
- creating instances of Generator
- creating instances of Parser
- triggering popup windows
- calling Generator.generateRequest()
- checking to make sure the classes are valid
- making sure a class can be instantiated
The intent of this sampler is it uses the generator and parser to create a HTTPSampler when it is needed. It does not contain logic about how to parse the logs. It also doesn't care how Generator is implemented, as long as it implements the interface. This means a person could simply implement a dummy parser to generate random parameters and the generator consumes the results. This wasn't the original intent of the sampler. I originaly wanted to write this sampler, so that I can take production logs to simulate production traffic in a test environment. Doing so is desirable to study odd or unusual behavior. It's also good to compare a new system against an existing system to get near apples- to-apples comparison. I've been asked if benchmarks are really fair comparisons just about every single time, so this helps me accomplish that task.
Some bugs only appear under production traffic, so it is useful to generate traffic using production logs. This way, JMeter can record when problems occur and provide a way to match the server logs.
