hi,
Nice thx for this contrib !
It would be cool if you can add at least one example in your parser XML definition like all other parsers (have a look here https://github.com/wallix/pylogsparser/blob/master/normalizers/apache.xml#L229). Thoses examples will be processed by unitests by adding a test method like this one https://github.com/wallix/pylogsparser/blob/master/tests/test_normalizer.py#L47.
Furthermore to detect conflict between parsers it would be cool to add an additional test in this file : https://github.com/wallix/pylogsparser/blob/master/tests/test_log_samples.py

I can't merge as I'm not a Wallix org member since I leave. I don't know about mhu. Maybe Lahoucine will be able to merge your contrib. Or should we fork that project in our account ???

Hey Fabien, thanks for the feedback.

I'm going to add the examples and tests as you suggest, so maybe Wallix should wait a bit before accepting this pull request. Hopefully I'll find some time to do it this week.

As far as taking over the project to our account, are you sure you want to do this?

By cloning the project we'll be able to accept pull requests quickly. Maybe you can ask mhu, what he is thinking about :)

There's a big shiny "pull request" button on my interface so I should be able to merge it from here. But as far as I remember this repo is synchronized with a private one @wallix that acts as the reference. I am not sure how merging from github will impact their private repo.
Cloning is always a possibility, though there might be some conflicts if we want to push the clone to PyPI and so on.

It'd be nice if you could modify some of the tag names you use according to the best practices : https://github.com/wallix/pylogsparser#tag-naming-convention

I'd also suggest renaming the "tenant" tag into "tenant_id".
