OK, so today I confirmed that you can in fact export data from the
Windows event log into a plain CSV file. Which is great.
(Unfortunately, sometimes event descriptions contain line breaks, which
is not so great.)
Anyway, I wrote a small Haskell program that deletes any multi-line
events, and then another which grabs only the events I care about and
does some trixy parsing of the event description to pull out the data I
actually want. The result is a big CSV file containing a list of printer
events - date, time, user, printer and page count.
(There is *one* event in the log that says something like "document %4
was printed on %6, byte count: %7, page count: %8". Which is really not
especially helpful...)
So now I have a CSV file that contains the date, time, user, printer and
page count. Just import that into Access and produce some stats, right?
Wrong! Access apparently can't parse any of the dates. Despite them all
being perfectly valid dates (and it even *detects* that this column
should be a date column), it fails to parse every single last one. >_<
So I used Haskell (which is really the wrong tool) to produce some
statistics the hard way - by manually scanning the CSV file, reparsing
the data and writing the results into yet *another* CSV file.
And now, finally, I have a chart showing me how many pages each printer
printed on a given day. Which is all I wanted in the first place!
Mmm, apparently that printer in the corner hasn't printed a single
damned page since July... Yep, it's definitely spare. :-)
