Comming soon!

comming soon to a terminal near you!

* sorting:
* more statistics
  (hits, number of hits per response type like 200, 302 etc)

May be… but don't expect any of these to become a reality I love programming and tons of ideas flow in my head with posibilities but I do not have the time! :(

* Different export drivers?
  (should be another plugin)

* cli options abstracted into classes so they can be aggregated with ease
  (this might be cool)

* google charts integration
  (is too much for this api)
  (may be as a different plugin)


* FileUtils
* MD5
* File
* Dir
* rubygems 1.3.3


Compiles statistics in a easy to read manner

  • Send me a brief message

  • Fork the project.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Make your feature addition or bug fix.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but

    bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.


All output is packed in a plog directory, from wherever you run the “plog” executable.

Inside this directory you'll find a directory called objects. wich contains many small files called “object-files” this files contain all the parsed statistics of you log files.

The information is scattered and can be reused for future compilations meaning that new compilations data will merge with the existing one.

all data in these “object-files” is read and summarized into a statistics.txt file found inside of the plog directory.


* 70% tested, with shoulda
* all core areas of the api are tested, and tests pass!
* only the cli part of the api has no tests, but will be implemented soon


The “plog” ( production log ) executable receives one option. This must be a directory containing one or more production logs. Only logs in the first level will be parsed. Recursive reading is not allowed

$ plog directory_with_logs/
