I find the logger script, its looks enough accurate. Its simple script that keeps a log of everyone who "hits" the page, keeping the information in one file.
What I want is add one feature - logs emailing feature.
Emaling need be configurable, i.e. logfile will be emailed after "hits" exceed predefined 'hits' quantity, even after 1 hit). Emaling feature can be turned off if not required. Also, can be used txt for logfile, main.txt not .log? Excecuting script should be via image tags, not SSI. Probably ,it possible to return a location header that points to an existing image url, one pix gif. Or print image.
I was wondering if someone can help me. Its looks not difficult task..

#! /usr/local/bin/perl

# logger.cgi
# version 1.0
#
# Create a file called main.log. Must have write permissions
# set to main.log

$mainlog = "main.log";
$shortdate = `date +"%D %T %Z"`; 
chop ($shortdate);
print "Content-type: text/plain\n\n ";
open (MAINLOG, ">>$mainlog");
print MAINLOG "Time: $shortdate\n";
print MAINLOG "User: $ENV{'REMOTE_IDENT'}\n";
print MAINLOG "Host: $ENV{'REMOTE_HOST'}\n";
print MAINLOG "Addr: $ENV{'REMOTE_ADDR'}\n";
print MAINLOG "With: $ENV{'HTTP_USER_AGENT'}\n";
print MAINLOG "Page: $ENV{'DOCUMENT_URI'}\n";
print MAINLOG "From: $ENV{'HTTP_REFERER'}\n\n";
close (MAINLOG);
exit;
