Not that we heard of.

Lire is meant to be used for that kind of purpose. Unfortunately, we
currently lack good tutorial material which explains how to start. You
can take a look at the developer's manual which contains a lot of
reference material but not much in the area of practical examples. You
can read the first chapter which gives an high-level overview of
the concepts involved. 

After that, the best solution is to learn by copying. You can inspire
yourself from one of the simpler superservice like firewall.

To be able to generate reports for the JMeter application, here are the
basic steps involved:

1- Define a schema for the log data (this is an XML file, look at
firewall.xml for an example). 

2- Write a converter from the application log format to Lire's DLF. This
is a script which reads the log file on STDIN and writes the DLF on
STDOUT. You can take a look at ipchains2dlf for an example. A converter
for JMeter's log file would be a little more complicated since it would
probably use XML::Parser to parse the log file.

3- Write report specifications and combine them in a report
configuration file (you can look at the files under firewall/reports for
example specifications and firewall.cfg for the report configuration).

The report configuration format is described at length in the User's
manual. The developer's manual contains the description of all the
elements available in the report specification markup language.

Hope this helps you get started. If you need more help, don't hesitate
to post on our development mailing list development at logreport.org

 
Thanks for your interest in LogReport, kind Regards,
