<div class="block">Description:<br>
<br>
Filter interface is designed to make it easier to use Access Logs for JMeter
test plans. Normally, a person would have to clean a log file manually and
create the JMeter requests. The access log parse utility uses the filter to
include/exclude files by either file name or regular expression pattern.
<p>
It will also be used by HttpSamplers that use access logs. Using access logs
is intended as a way to simulate production traffic. For functional testing,
it is better to use the standard functional testing tools in JMeter. Using
access logs can also reduce the amount of memory needed to run large test
plans. <br></div>
