KAZIMIR
KAZIMIR is a log analyzer, fully written in PERL. It is available under the CeCILL license, which is a French transposition of the GPL and is fully GPL-compatible. KAZIMIR looks at several logs of several different types,
try to find user defined problematic or pathologic situations in these
logs and eventually (based on user-defined configuration) does action
to signal or correct the situation. The reason why I developed such a
tool is my own job: I was working as a sysadm and it's hard to keep an
eye on every log at all time to locate problems when they occur. The
detection's procedure could be easily automated, so I write Kazimir to
do this work instead of me.
Kazimir is written in PERL for two main reasons: it is a fully portable
language, and I needed an interpretor for several part of Kazimir, and
regexp management was also critical; PERL has such features, and it was
a good thing to use the PERL interpretor (that is fully tested and
validated)
instead of re-writing one from my own. There are several similar tool
like Kazimir, some are very simple, some are very complicated. I made
Kazimir to be a kind of compromise between all
the tools that I've seen. I also added chronological pattern matching
(see below), a feature that I needed and found nowhere. I also wanted a
tool that I would know well enough to modify it quickly if I had a new
need. Writing a new tool was far the best way to achieve this
