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.

getFilterClassName
public String getFilterClassName()
- Returns the filterClassName.
getLogFile
public String getLogFile()
Get the path where XML messages are stored. this is the directory where
JMeter will randomly select a file.
getParserClassName
public String getParserClassName()
Get the file location of the xml file.
getPortString
public String getPortString()
initFilter
protected void initFilter()
instantiateParser
public void instantiateParser()
Method will instantiate the log parser based on the class in the text
field. This was done to make it easier for people to plugin their own log
parser and use different log parser.
isImageParsing
public boolean isImageParsing()
- Returns the imageParsing.
sampleWithParser
public SampleResult sampleWithParser()
sample gets a new HTTPSampler from the generator and calls it's sample()
method.
setFilterClassName
public void setFilterClassName(String filterClassName)
filterClassName
- The filterClassName to set.
setImageParsing
public void setImageParsing(boolean imageParsing)
imageParsing
- The imageParsing to set.
setLogFile
public void setLogFile(String path)
Set the path where XML messages are stored for random selection.
setParserClassName
public void setParserClassName(String classname)
it's kinda obvious, but we state it anyways. Set the xml file with a
string path.
classname
- -
parser class name
setPortString
public void setPortString(String port)
