Extracting JTL files to CSV with Python (JMeter 2.3.x)
This script does two things. First it filters the JTL file for a regular expression. Then it strips them and outputs a CSV file. This also includes the conversion of the timestamp to a readable format.
The script only works with JTL files from JMeter 2.3.x (JTL version 2.1). Please see http://jakarta.apache.org/jmeter/usermanual/listeners.html#xmlformat2.1 for details.
Usage is:
" program.py <JTL input file> <CSV output file> "<regular expression>"
