[SUBMIT] Perl script to split logfiles
We've talked for a long time about how a simple script can be used
to split up a logfile common to all virtual hosts. Here's one I
hacked together; anyone think its worth adding to src/support?
#ken P-)}
#!/usr/local/bin/perl
#
# This script will take a combined Web server access
# log file and break its contents into separate files.
# It assumes that the first field of each line is the
# virtual host identity (put there by "%v"), and that
# the logfiles should be named that+".log" in the current
# directory.
#
# The combined log file is read from stdin. Records read
# will be appended to any existing log files.
#
%is_open = ();
while ($log_line = <STDIN>) {
#
# Get the first token from the log record; it's the
# identity of the virtual host to which the record
# applies.
#
($vhost) = split (/\s/, $log_line);
#
# Normalize the virtual host name to all lowercase.
# If it's blank, the request was handled by the default
# server, so supply a default name. This shouldn't
# happen, but caution rocks.
#
$vhost = lc ($vhost) or "access";
#
# If the log file for this virtual host isn't opened
# yet, do it now.
#
if (! $is_open{$vhost}) {
open $vhost, ">>${vhost}.log"
or die ("Can't open ${vhost}.log");
$is_open{$vhost} = 1;
}
#
# Strip off the first token (which may be null in the
# case of the default server), and write the edited
# record to the current log file.
#
$log_line =~ s/^\S*\s+//;
printf $vhost "%s", $log_line;
}
exit 0;
