OPLP: Ocaml APache Log Parser

Dear Everyone,

I just wanted to let Ocaml'ers know that I am currently working on an
apache combined log parser.  It is still in very early stages of
development but patches/comments/feature requests/bug reports are very
welcome.  The code lives on github (http://github.com/cyocum/OPLP).

All the best,
Chris Yocum

Aha... long ago I had done something similar, and it had an sql-like
language for using it.

The annoyance (and advantage ;)) with the apache logfiles is, that there
are many "standard" formats, and you also can design your own output format.

So it would make sense (I didn't do that) to parse the apache config files,
and create a logparser from that information...

Do you have planned to do this, or do you want to stick with some of the
most used formats?

Ciao,
   Oliver

Hi Oliver,

For now, I was just concentrating on the "combined" format that is used
as an example on the apache site.  I will probably branch out into
parsing the log format itself later once I get more experience with it.

Also, does anyone have a smallish block of apache log files (<30k) that
I can use for testing?

All the best,
Chris Yocum

I do something like this, but using OCaml to load a logfile into  
SQLite, and analyze it with "real" SQL.



http://gaiustech.wordpress.com/2010/09/12/analyzing-logfiles-1/



Probably my technique using sscanf wouldn't be fast enough for  
something as big as an Apache log that might have a million lines.



Cheers,




G

I would like to encourage you registering your project to the forge:
http://forge.ocamlcore.org/

Using github is not a problem, but there is an effort to make OCaml big
& small project visible. Let's also encourage it.
