+The results will be stored in the specified output dir. Each file will be named with the format: *<variable-name>\_<server-name>\_<subvariable-name>.txt*. The subvariables depend on the kind of variable. For example, with the disk space usage variable, the subvariables will be each partition.

+The result files contain one value per line, with the date and the value, separated by a tab. The date is in the ISO format: year-month-day (ex.: 2013-09-10). The values are not ordered by date. You may want to order them using the *sort* unix command.

-This is the default page, edit it as you see fit. To add a new page simply reference it within brackets, e.g.: [SamplePage].
+This tool extracts variables from [LogWatch](http://www.logwatch.org) reports so that you can visualize tendencies and detect or prevent errors on your servers. It generates a file for each variable and server in an easily parseable format, and usable by other tools like [gnuplot](http://www.gnuplot.info/).

-The wiki uses [Markdown](/p/acorelogparser/wiki/markdown_syntax/) syntax.
+Currently it extracts the following variables:

-[[members limit=20]]
-[[download_button]]
+* Percentage of disk space usage per partition.
+* Raw read error rate, per disk, from the smartd daemon.
+* Disk temperature, per disk, from the smartd daemon.
+* Number of errors 500 in your apache server.
+
+Installation
+------------
+
+Download the tarball from the files section, extract and compile it. It doesn't depend on other libraries, but you'll need a C++ compiler. After a successful compilation, you can run *make install* as root to install it systemwise.
