The way this should work is on a priority basis; 1st priority is errors, 2nd is warns and last is the greenlight. If the program parses my log and finds a red, it stops and prints a red light; that's it. Or, if there are no reds in the file, but the script snags a warning, it will show a yellow light and end. If the script sees neither warnings nor errors in the log file, the script will print one green light and stop. What would you suggest would be the best way to do this? Here is my latest: 
use strict;
use warnings;
my $logfile="log.txt";
my $error="DOWN";
my $warn="PROBLEM";
my $redbutton="\<img src\=\'default_files/perlredblink\.gif'>";
my $greenbutton="\<img src\=\'default_files/perlgreenblink\.gif'>";
my $yellowbutton="\<img src\=\'default_files/perlyellowblink\.gif'>";
open LOG, $logfile or die "Cannot open $logfile for read :$!";
my $button = $greenbutton;
while ($_ = <LOG>) {
if ($_ =~ /$error/i) {
  $button = $redbutton;
    print "<!--Content-type: text/html-->\n\n";
     print "$button";
     last;
  }
elsif ($_ =~ /$warn/i) {
  $button = $yellowbutton;
    print "<!--Content-type: text/html-->\n\n";
     print "$button";
     last;
  }
else {
    print "<!--Content-type: text/html-->\n\n";
    print "$button";
    last;
  }
}
close LOG;
